xmlwebgui requires the following systems to be already installed in your system:
Java Virtual Machine A Java 1.2 or later compatible virtual machine must be present for usage of xmlwebgui
Note that all servlet engines require a JVM to run so if you are already using servlets you already have one installed.
If you don't have a servlet engine installed, well, stop right here and go to the Apache Tomcat project http://jakarta.apache.org/tomcat/ then come back when you are done.
