Hi, it seems like you've got to clean up your environment variables.
java.lang.NoClassDefFoundError generally means that the ClassLoader couldn't find the correct jar files (ie the classpath is wrong). Standard practice by java applications is set a JAVA_HOME variable which points to the root directory of your installation. On your machine it seems to be 'C:\java1.3.1_02. However you also referenced a difference installation at the same 'C:/Program Files/JavaSoft/JRE/1.2.1_02. This isn't consistent. Furthermore it is also general practice to set a TOMCAT_HOME when using Tomcat. One well known trick with Tomcat is that it loads the jars in its lib directory alphabetically, and different versions of a XML Parser conflict. Usually you only use the Xerces parser, but this would be the last one that gets loaded. It often helps to move it up the list by prefixing the file name with a "A" for example. (Advanced users please cast a blind eye). Please note, this kind of question has little relevance to this list. Please consult docs about setting environment variables, the installation guide for Tomcat, and the Tomcat users list first.
