This software requires a Java 2 SDK (J2SE) and has been tested using version 1.3 standalone and via the Plugin on Windows and Linux.
CLASSPATH
Your environment CLASSPATH must include the jwebdata.jar file provided with this installation.
If you intend to use XML you must also include Java API for XML Processing (JAXP) support. Java Developer Connection members can download the required JAR files - called jaxp.jar, crimson.jar and xalan.jar - or you can use the J2EE Reference Implementation v1.3 (beta). Please refer to for more http://www.javasoft.com information.
