Web Integration
For DE-Light exists a DE-Light Web client that enables any Web browser supporting Java to access TXSeries and DCE services. DE-Light Web client does not need DCE or TXSeries on the client. It is implemented as a set of Java classes, which are downloaded automatically from the Web server each time the browser accesses the Web page referencing the client. DE-Light Web also has minimal requirements for
RAM and disk.
