Editors
In the JSF Tools Reference Guide and Struts Tools Reference Guide you may have read about
the Graphical Editors for JSF and Struts configuration files, Tiles Files, and Struts Validation Files.
All these editors have OpenOn (see Section 3.1.1, “OpenOn”) and Code Assist (see Section 3.1.2,
“Content Assist”) features, which are described in more detail in this document. In addition, this
document will cover the Visual Page Editor (see Section 3.2, “Visual Page Editor”), which provides
combined visual and source editing of Web pages, as well as a number of additional editors (see
Section 3.3, “More Editors”) for different types of files.
3.1. Editors Features
JBoss Developer Studio has powerful editing features that help you easily navigate within your
application and make use of content and code assist no matter what type of project file (JSP,
XHTML, XML, CSS etc.) you are working on.
The mentioned features are the following:
• Section 3.1.1, “OpenOn”
• Section 3.1.2, “Content Assist”
• Section 3.1.3, “Synchronized Source and Visual Editing”
3.1.1. OpenOn
OpenOn lets you easily link directly from one resource to another in your project without using the
Package Explorer view (i.e. the project tree). With OpenOn, you can simply use F3 or Ctrl+Click
on a reference to another file and the file will be opened.
OpenOn is available for:
• Section 3.1.1.1, “XML Files”
• Section 3.1.1.2, “JSP/XHTML Pages”
• Java files
• Section 3.1.1.3, “CSS Classes”
• Section 3.1.1.4, “OpenOn for EL variables”
3.1.1.1. XML Files
When editing an XML file press and hold down the Ctrl key. As you move the mouse cursor over
different file references in the file, they are displayed with an underline. In this state these file
7
Chapter 3. Editors
references effectively become links, and when they are clicked the appropriate file will be opened
in its own editor.
Use the OpenOn functionality for the next entries defined in XML file:
1. Managed beans
In this example source code of the managed bean User will be open.
Figure 3.1. Opening a Managed Bean
The image below shows the result of using OpenOn.

3.1.3. Synchronized Source and Visual Editing
JBoss Developer Studio offers the ability to edit the source code of a file, as well as providing
visual editors for many file types. The source code and visual editors can be viewed and edited
at the same time in a split screen view, and any changes you make in the source code editor will
immediately appear in the visual editor.
The JSF configuration file editor has three views: Diagram, Tree and Source. All views are
synchronized and you can edit the file in any view.
Figure 3.39. Three Views are Synchronized
The same is true of all other JBoss Developer Studio editors.
46
Synchronized Source and Visual Editing
The Web XML editor is shown. The Web XML editor has a graphical view, accessed by the Tree
tab, and a source view, accessed by the Source tab.
Figure 3.40. Two Views are Synchronized
The JBoss Developer Studio TLD file editor is shown below in Tree view. At any point you can
edit the source by switching to the Source view.
47
Chapter 3. Editors
Figure 3.41. Two Views are Synchronized
3.2. Visual Page Editor
JBoss Developer Studio comes with a powerful and customizable Visual Page Editor (VPE). You
can use the Visual Page Editor to develop an application using any technology such as JSF,
Struts, JSP, HTML and more. Double-click on a file in the Package Explorer view to open it in
the Visual Editor, or just drag-and-drop it into perspective (the drag-and-drop feature can be also
applied to JSP, XHTML or HTML files created locally).
As a new JSF 2.0 specification has been released, support of new features is now implemented
in the Visual Page Editor. The JSF 2.0 tags like <h:body>, <h:head>, <h:outputscript>,
<h:outputstyle> are supported in the editor, as well as the composite components and
expression language resource handling. (See the JSF 2 fu, Part 2: Templating and composite
components [http://www.ibm.com/developerworks/java/library/j-jsf2fu2/index.html] for information
on how to use composite components and JSF 2.0 New Feature Preview Series (Part

3.2.1. Visual/Source View
Using the Visual/Source view you can edit your pages in the Source and Visual modes
simultaneously, with instant synchronization between them:
49
Chapter 3. Editors
Figure 3.43. Visual/Source View
The view is designed in the form of a split pane with toggle buttons for quickly moving between
Source, Visual or Source/Visual modes, as shown on the figure above.
One more way to toggle between the various states of the split pane is using the Shift+F6
keyboard shortcut for maximizing or restoring the Source part and Shift+Alt+F6 for maximizing
or restoring the Visual part.
You can synchronize the scrolling between the source and visual
by clicking the Synchronize scrolling between source and visual
panes

(
button in the toolbar of the Web Development perspective. This will ensure that scrolling in one
window pane will automatically scroll the other pane to the same location.
Tip:
When editing large documents hiding the Visual part will speed up the editing.

)
Visual/Source View
It should be pointed out that, no matter what mode you are working in, you get a full integration
with the Properties and Outline views:
Figure 3.44. Integration with Properties and Outline Views
The Outline view displays a specific outline of a structured file that is currently open in the editor
area, and lists its structural elements. Right-clicking on these elements will open additional options
that allow other specific elements to be added in their appropriate positions.
The Properties view shows the property names and their values for a selected item. The values
are editable: just select any value and click on the button that will appear to choose a new value.
The key combination Ctrl+Z will return the previous value, while Ctrl+Y will return the new value
again. The Properties view has additional options and can be set up to display categories and
advanced properties.
It is also possible to use the JBoss Tools Palette (see Chapter 5, JBoss Tools Palette) to insert
any tag from the list of tag libraries into the page you are editing with just a click or by draggingand-dropping.
51
Chapter 3. Editors
Figure 3.45. Inserting Tag From the Palette
You can insert a tag or component from the palette into either the Source or the Visual part by
displaying the context menu and selecting Insert around, Insert before, Insert after or Replace
With, picking the type of the tag and finally choosing the tag you want to insert.
The image below illustrates how you can insert a tag into the Source part.

Visual/Source View
When you make a selection of tags in the source part of the editor, they will all be selected in
the visual part of the editor as well. This makes it easy to link code that you have written, with
the visual output.
Figure 3.50. All tags from the source selection are selected in the visual part
3.2.1.1. Commenting out Code
The Visual Page Editor supports the ability to add comments in files you are working with (JSP,
XHTML, etc.):
• HTML comments ( <!-- --> ) which are output to the client
• JSP comments ( <%-- --%> ) which are not output to the client as part of the JSP page output
3.2.1.2. Using Code Folding
The Visual Page Editor lets you collapse and expand (or hide and show) sections of your code
to make it easier to navigate and read.
Code folding can be enabled by right-clicking on the left margin on the Source part of Visual Page
Editor, selecting Folding, and checking the Enable Folding checkbox or using the Ctrl+Numpad
Divide shortcut.
When
the
code
folding
is
enabled
a
minus
sing
(
) will appear on the left margin of the editor next to each opening block tag.
57
Chapter 3. Editors

Chapter 3. Editors
3.2.1.5. Support for custom TagLibs and Taglib versions
VPE templates support custom tag libs, e.g. Seam Mail facelet taglib, RichFaces taglibs or any
other created by you.
VPE templates also provides support for various versions of tag libraries, meaning that the Visual
Page Editor takes control over those components which have different parameters or preview
according to the framework version (like seam 1.2 and seam 2.0, or JSF 1.1 and JSF 1.2).
For example, the <s:decorate> element in Seam has different parameters in versions 1.2 and
2.0, and the <h:outputLink> JSF element has different preview in versions 1.1 and 1.2.
3.2.2. Pages Styling
Most web pages use the cascading style sheets (CSS) to control the way they look. With Visual
Page Editor you can easily stylize your pages. In this section we are going to introduce you
to a powerful mechanism that Visual Page Editor provides for complete control over a pages'
styling. Additional information on working with CSS files can be found in Chapter 6, CSS Editing
Perspective
3.2.2.1. Text Formatting
In the Visual part of the Visual Page Editor there is a graphical toolbar,
which is used to add inline styling to JSF and Struts tags on your
page. The toolbar can be hidden with the help of the special button (
) on the Visual Page Editor toolbar.
Figure 3.55. Text Formatting
60
Pages Styling
For editing inline styles for DOM elements, the Visual Page Editor provides the CSS Dialog. It
can be called from the style line in the Properties view of a currently selected element.
Figure 3.56. Call the CSS Dialog
The CSS Style dialog has several tabs where CSS properties for text, background, borders and
others can be specified. A simple preview which is generated at the top of the CSS Style dialog
allows you to see the changes before you apply them.
61
Chapter 3. Editors
Figure 3.57. CSS Style Dialog
3.2.2.2. External Stylesheets (CSS)
The pages you are working with in the Visual Page Editor can use external stylesheets.
3.2.2.2.1. Importing a stylesheet
You can import an existing stylesheet by using the @import annotation within your webpage file.
The annotation for importing a file is structured as @import "path/to/file.css";.
An example of how it is used can be seen below:
62
Pages Styling
Figure 3.58. Importing a stylesheet
3.2.2.2.2. Modifying an existing stylesheet
The Visual Page Editor allows you to create new style classes in existing stylesheets, as well as
edit them. The Edit Style Class dialog is provided for this purposes.
Select the element for which you need to create or edit style class, and press button next to the
styleClass field in the Properties view.
Figure 3.59. Calling the Edit Style Class Dialog
This will display the Edit Style Class dialog, which is shown in the image below:

The Tag Name field is used to define the name of the unknown tag.
Note:
The given field should be filled in according to the pattern: taglib:tag. Also
make sure you do not surround the name with angle brackets which will cause the
validation error (see the figure below).
Figure 3.71. Validation Error in the Template Dialog
The Tag for Display field in the Template dialog requires specifying a type of tag. It can be SPAN,
DIV, TABLE or any other HTML element. Check the Children field if you want to mark a tag as
a child element.
The Value defines a tags' value.
As for the Style field, you can fill it out manually or make use of the button next to the field to bring
the CSS Style dialog (See Section 3.2.2.1, “Text Formatting” [61]) for editing styles.
You can view all defined templates in the Section 9.3, “Visual Page Editor”
on the Visual Templates tab which, you can quickly access by pressing the
toolbar button (see Section 3.2.5, “VPE Toolbar”).

The second tab, Included CSS files, is used to add CSS files to be linked by Visual Page Editor
when generating a preview:
84
VPE Toolbar
Figure 3.81. Page Design Options: Included CSS files
The third tab, Included tag libs, can be used to add Taglibs that can be used by the editor for
getting appropriate templates to generate a preview:
Figure 3.82. Page Design Options: Included tag libs
85
Chapter 3. Editors
And finally, the Substituted El expressions tab is used to add El expressions that will be
substituted by the editor when generating a preview:
Figure 3.83. Page Design Options: Substituted El expressions
The first two tabs of the window let you define actual runtime folders. The example below will help
you understand how this can be done.
Suppose you have the following project structure:
WebContent/
pages/
img/
a.gif
header.jsp
main.jsp
The content of the header.jsp is:
My Header
<img src="img/a.gif"/>
86
VPE Toolbar
and main.jsp content is:
<jsp:include page="pages/header.jsp" />
When you open the main.jsp file in the Visual Page Editor, it will not be able to resolve the
image from the header, however it will work fine in runtime. To fix this in design time, click the
Page Design Options button and set Actual Run-Time Relative Folder to [Project Name] →
WebContent → pages, and you will see the image appeared.
Let's consider an example for other tabs. For instance, the definition of your CSS on the page
is the next:
<link rel="stylesheet" type="text/css"
href="#{facesContext.externalContext.requestContextPath}/style.css"/>
This will work fine in runtime, but the Visual Page Editor does not know the value of
requestContextPath in design time. In order to see the necessary styles applied in design time
your should add a path to your stylesheet in the CSS File Path section.
The next URI section lets you add URI taglibs so that the editor knows where to find the tag
libraries.
And the last Substituted EL expressions section is provided to specify the values for specific EL
variables. It can be useful for a preview generation.
As an example look at the figure below:
87
Chapter 3. Editors
Figure 3.84. EL Expression
Here both in Source and Visual modes you see the EL expression #{user.name}. When you
switch to Preview view, you will also see this expression. Now click the Page Design Options
button and set the value for the user.name as World.

Chapter 5.
JBoss Tools Palette
This chapter will introduce you to the functionality provided by JBoss Tools Palette. The Palette
allows you to quickly and easily create your JSP or JSF pages.
The JBoss Tools Palette allows you to:
• Insert tags into a JSP or JSF page with one click
• Add custom and 3rd party tags
The JBoss Tools Palette contains a developer's project tag libraries and provides possibility to
add any tag libraries to it. Also you can choose a necessary one from the list of already existing
tag libraries:
• HTML
• JBoss
• JSF
• JSTL
• MyFaces
• Oracle ADF Faces
• Struts
• XHTML
Figure 5.1. Default View of The JBoss Tools Palette
By default the JBoss Tools Palette is not displayed. If you want to use it select Window → Show
View Other... → JBoss Tools Web → JBoss Tools Palette from the menu bar.
The standard Eclipse Palette is displayed by default in both Web Development and Seam
perspectives. Now the standard Eclipse Palette is featured with all JBoss Tools Palette options
and capabilities.
137
Chapter 5. JBoss Tools Palette
To open the standard Eclipse Palette navigate to Window → Show View → Others → General
→ Palette.
The differences between the two palettes are as follows:
• The standard Eclipse Palette is blank by default. Content of the palette is available only if Visual
Page Editor is open and active, while JBoss Tools Palette always contains a predefined set
of components.
• The Expanded/Collapsed state of components in the standard Eclipse Palette is not global as
in JBoss Tools Palette. State is associated with an instance of Visual Page Editor. It means
that the state can be different for various files and each new file opened in Visual Page Editor
will have the default state of Palette with all components collapsed.
5.1. Palette Options
The Palette can be customized by using the following buttons on the Palette toolbar, which provide
the following functionality:
• editing the palette content by adding, removing or changing the palette elements
• showing or hiding groups and subgroups
• importing groups and subgroups
Figure 5.2. Palette Buttons
5.1.1. Palette Editor
The JBoss Tools Palette contains existing libraries of tags, and the Palette editor provides a
way to add a new library, or edit existing libraries.
138
Palette Editor
To
open
the
editor,
click
on
the
Palette
Editor
icon
(
).
The window has two parts. There is a reflected grouped list of components on the left side of the
palette editor. Each group is divided into multiple groups, each of which is a tag library. To the
right side of the palette editor is an editing window where it is possible to change values of group
or tag library attributes that you have chosen on the left part of the window.
It can also be done by right click and using Edit… option.
For example, JSF group consists of Core, Facelets, HTML tag libraries and the attributes as
name, description and hidden which are available for editing:
Figure 5.3. Tag Libraries of the JSF Group
The Palette Editor provides the following functionality when working with existing tags or icons:
• To work with a set of icons. Icons is the root folder for the icon sets. The first step is
creating the icon set. Right click on the Icons folder and select Create → Create Set....
Set the value of the name in the Add Icons window and click the Finish button. A new element
will appear in the list.
139
Chapter 5. JBoss Tools Palette
Figure 5.4. Creating a Set of Icons
Also you can delete the set. Right click on the set of icons that you wish to remove and select
the Delete option from the pop-up menu, or click the Delete keyboard button.
• To edit icons in the chosen set. When the set of icons is created, new icons can be imported
to it. Choose the required set and select the option Create → Import Icon... from the pop-up
menu that appears after you right-click on a folder.
140
Palette Editor
Figure 5.5. Creating Icons

If you do not choose an icon the default one will be assigned.
You are allowed to edit or delete the tag library, as well. If you'd like to change attributes of the
library or choose another icon, use the right editing window of the palette editor or the Edit...
option. In order to remove the tag library, right click on the library that you wish to remove and
chose the Delete option or click the Delete keyboard button.
Important:
The removal option is enabled only for custom tag libraries.
• To work with a tag element. When the library folder is created, new tags can be added to
it. Choose the required library and select the Create → Create Macro… option from the popup menu that appears after you right-click on a folder.
143
Chapter 5. JBoss Tools Palette
Figure 5.8. Creating a tag element
In the Add Palette Macro window you can configure the tag element. The Name attribute is
mandatory, as it defines the name of the tag element. Other settings are optional. You can
choose the icon and set the Start Text and the End Text for your tag element. If your tag text
is too long, use the Change... button to see it all. The pipe ("|") symbol can be used to control
the cursors position for the start text and end text values.
144
Palette Editor
Figure 5.9. Parameters of the Palette element
After all the attributes are set, click the Finish button.
Note:
If you do not choose an icon the default one will be assigned.
You are also allowed to edit or delete the tag. If you would like to change the attributes of the
tag or choose another icon for it, use the right editing window of the palette editor or the Edit...
option from the pop-up menu. In order to remove the tag, right click on the tag that you wish to
remove and chose the Delete option, or click the Delete keyboard button.
Important:
The removal option is enabled only for custom tags. JBoss Palette tags can not
be removed but can be modified.
If you have changed any object in the tree view and you don't like the final result you can always
use the Restore Defaults button. Clicking this button will restore defaults for the object selected
and for its children elements. Please remember that the button will only restore data for objects
defined in the default palette. If selected object is created by you, the button will be disabled. Child
objects added by you will not be removed.
145
Chapter 5. JBoss Tools Palette
When updating JBoss Tools the palette content is not updated.
5.1.2. Show/Hide
Show/Hide is a very useful feature that allows you to control the number of tag groups that are
shown on the palette.
• Click
the
Show/Hide
button(
), at the top right side of the JBoss Tools Palette.
• In the dialog Show/Hide Drawers check the groups the libraries of which you want to be shown
on the palette:
Figure 5.10. Show/Hide Drawers
If libraries are not displayed in the palette, check whether they are selected. Click the plus sign to
expand the libraries of the group and make sure that a tick is put next to the wanted libraries.
• Click the OK button. The new groups will now be shown on the palette:
146
Import
Figure 5.11. New Added Groups
The names of the elements are compound. The first part is the group name and the second is
the library name.
5.1.3. Import
The Import button lets you add a custom or 3rd party tag library to JBoss Tools Palette. Find out
more information on how to add particular tags see the Section 5.2.2.2, “Import Button” section.
147
Chapter 5. JBoss Tools Palette
5.2. Using the Palette
5.2.1. Inserting Tags into a JSP File
A new tag can be added into any text file including JSP, HTM, HTML and XHTML.
Open your JSP file, place the cursor in a place where you would like to add a tag, and then click
that tag in the palette. In the Insert Tag window that appears, you can set the value of general
and advanced attributes of the tag that you choose.
Figure 5.12. Inserting Tag
In the example below the commandButton tag has been inserted.
148
Inserting Tags into a JSP File
Figure 5.13. Inserting Tag
Tip:
If you place the cursor over any tag, a balloon hint is shown with all the tag
attributes.
The cursor position after adding a tag into a file is specified by "|" symbol in the tag template on
the right in the Palette Editor window.
149
Chapter 5. JBoss Tools Palette
Figure 5.14. Palette Editor
Above you can see where the cursor position for HTML → Form → input is set. After adding
this tag into your file the cursor will be in the attribute type. At this point you can straight use the
Ctrl+Space keyboard shortcut to display a list of possible values.
Figure 5.15. Cursor position
5.2.2. Adding Custom JSF Tags to the JBoss Tools Palette
There are two ways to add any custom (including custom Facelets libraries) or 3rd party tag library
to the JBoss Tools Palette:
• Drag-and-drop from the Web Projects view
150
Adding Custom JSF Tags to the JBoss Tools Palette
• The Import button on the JBoss Tools Palette
Before you add your custom component library, you need to make sure it is included in your
project. You need to either place the TLD file or the JAR that includes your tag library under the lib
folder in your project. Or you can just add TLD or JAR file to the classpath and the library will be
added to the Tag Library List in Web Projects View.
5.2.2.1. Drag-and-Drop
Switch to the Web Projects view and expand the Tag Libraries folder. If the view is not active,
select Window → Show View → Web Projects from the menu bar.
Figure 5.16. Web Projects View
Also make sure that the JBoss Tools Palette is open. Select the tag library that you want to add
and simply drag-and-drop it on to the the JBoss Tools Palette.
You will see the following dialog window. As you can see JBoss Developer Studio takes care of
all the details. Chosen TLD file, name and prefix of the library and Library URL are detected
thus just need to set the Group name to which you wish to place this tag library. You can either
add this tag library to an existing Group or just create a new one.
151

CSS Editing Perspective
In this chapter we will discuss CSS Editing Perspective views. More information about style sheets
can be found in Section 3.2.2, “Pages Styling” of Editor chapter.
The CSS Editing Perspective combines a set of views which allow you to see the structure of your
css files, edit them and see the results. To use this perspective you need to select Window →
Open Perspective → CSS Editing. All of the views are fully synchronized with each other: the
changes being made in one view are reflected in the others.
As you know there are three ways of inserting a style sheet:
• External style sheet (.css file)
• Internal style sheet (using the <style> tag in the head section of an HTML/XHTML/JSP page)
• Inline style (using style attribute)
Using the CSS Editing Perspective you can change your style sheet, inserted in any of the
possible places described before in three ways:
• directly in your Editor
• using Section 6.3, “CSS Properties view ”
• using Section 6.2, “Properties view”

Web Projects View
Web Projects is a special view that comes with JBoss Developer Studio.
If the Web Projects view's tab is not visible next to the Package Explorer tab, select Window →
Show View → Other → JBoss Tools Web → Web Projects from the menu bar.
With the Web Projects view you can:
• Visualize the project better because the project artifacts for JSF, Struts and Seam projects are
organized and displayed by function.
• Select these kinds of items to drag and drop into JSP pages:
• JSF managed bean attributes
• JSF navigation rules outcomes
• Property file values
• Tag library files
• Tags from tag libraries
• JSP page links
• Use context menus to develop the application (all create and edit functions are available)
• Use icon shortcuts to create and import JSF and Struts projects
• Expand and inspect tag library files
• Section 5.2.2, “Adding Custom JSF Tags to the JBoss Tools Palette”
8.1. Project Organization
The Web Projects view organizes your project in a different way. The physical structure of course
stays the same. The new organization combines common project artifacts together which makes
it simpler to locate what you are looking for and develop.
The screen shot below shows a JSF project and a Struts project in Web Projects view.
171
Chapter 8. Web Projects View
Figure 8.1. Web Projects View
8.2. Drag and Drop
The Web Projects view has a drag and drop option that can be used for property, managed bean
attributes, navigation rules, tag library file declaration and JSP Pages.
8.2.1. For a Property
Expand the Resources Bundles folder that holds all the Property files in your project. Select the
file from which you want to add the property and then select the property.
We will be dragging and dropping a property file value inside the outputText tag for the value
attribute.
172
For a Property
Figure 8.2. OutputText Tag
Select the property:
Figure 8.3. Selecting Property
Drag the property and drop it between the quotes for the value attribute in the JSP file. Notice
that JBoss Developer Studio added the correctly formatted expression for referring to the property
value #{Message.header} automatically.
Figure 8.4. Inserted Property
173
Chapter 8. Web Projects View
You can actually place the tag anywhere in the page, not just inside an existing
tag. In this case JBoss Developer Studio will place the complete tag <h:outputText
value="#{Message.header}"/> in the page.
8.2.2. For Managed Bean Attributes
Select a "managed bean" attribute and then drag and drop it onto the JSP page. We are going to
place it inside the value attribute of the inputText tag.
Figure 8.5. Selecting Managed Bean Attribute
Once again, JBoss Developer Studio adds the correct expression, #{user.name}.

The first two items control the background grid for the diagram. The next two items allow you to
control the appearance of the labels for views (pages) and the transitions between views. For
these two items clicking the Change...button allows you to assign a font with a dialog box.
The first check box determines whether a view in the diagram that doesn't have a transition
connecting it to another view yet should be written to the source code as a partial navigation rule.
The next check box determines whether the diagram cursor reverts immediately to the standard
selection mode after it's used in the transition-drawing mode to draw a transition. Finally the
last two check boxes concern shortcuts. A shortcut is a transition that is there but isn't actually
displayed in the diagram as going all the way to the target view it's connected to, in order to make
the diagram clearer. With the check boxes you can decide whether to display a small shortcut
icon as part of the shortcut and also whether to display the target view as a label or not.

FAQ
11.1. What should I do if Visual Page Editor does not
start under Linux?
The Visual Page Editor requires the library libstdc++.so.5. This library is contained in the
compat-libstdc++-33.i386 package.
• To install this package on Fedora Core or Red Hat Enterprise Linux run the following command:
yum install compat-libstdc++-33.i386
• On any other rpm based distributions download libstdc++.so.5 and run the following
command:
rpm -Uvh compat-libstdc++-33.i386
• On Debian based distributions run the following command:
apt-get install compat-libstdc++-33.i386
In case you have the library installed and you still have issue with starting the Visual Page Editor
then close all browser views/editors and leave one Visual Page Editor open and restart eclipse.
This should force a load of the right XULRunner viewer.
If it doesn't help and you use Fedora Core Linux and Eclipse Version:
3.4.1,
the
issue
can
be
produced
because
libswt-xulrunner-gtk-3449.so
file doesn't present in eclipse-swt-3.4.1-5.fc10.x86_64.rpm/eclipse/plugins/
org.eclipse.swt.gtk.linux.x86_64_3.4.1.v3449c.jar. To add this file to eclipse you
should:
• Decompress eclipse/plugins/org.eclipse.swt.gtk.linux.x86_3.4.1.v3449c.jar from
eclipse-SDK-3.4.1-linux-gtk-x86_64.tar.gz
263
Chapter 11. FAQ
• Copy libswt-xulrunner-gtk-3449.so file to your Fedora Eclipse location.
• Open the file eclipse.ini,which can be found in your Fedora Eclipse location and add the
following line:
-Dswt.library.path=/usr/lib/eclipse
,where /usr/lib/eclipse is the path to your eclipse folder.
11.2. How do I change the auto-formating preferences
for the Visual Page Editor?
JBoss HTML/JSP editor uses basic eclipse HTML formatter to format files. So if you want to
change preferences of formatter for the Visual Page Editor, you should change it for eclipse html
editor (open Window → Preferences then choose Web → HTML Files → Editor).
11.3. Visual Editor starts OK, but the Missing Natures
dialog appears
Figure 11.1. Missing Nature
Some
functionality
of
Visual
Editor may not work if a project doesn't have
org.jboss.tools.jsf.jsfnature or org.jboss.tools.jst.web.kb.kbnature in .project
configuration. To fix this problem and turn off the message box execute next steps:
1. Right mouse button click on a project in Package Explorer.
2. Select Configure → Add JSF Capabilities from the context menu.
264
Visual Editor starts OK, but the Missing Natures dialog appears
3. Configure your project using Add JSF Capabilities wizard and press Finish.
If you are sure that your project does not need JSF capabilities, just disable this message box by
checking Do not show this dialog again! checkbox.
