Server encountered an internal error

Question

Hello,
I am new to JAVA and Tomcat. I have been tasked with creating a security option for adding new users. The programs were originally created in javascript for an OAS environment using Eclipse (it worked under this environment). The environment was changed to IIS and I was told not to use an SDK. So, I was converting to ASP and Jscript. Then, it was decided to use Tomcat (still will be IIS) and JAVA/Javascript.
The server currently has version 4.1.27 of Tomcat so I have that loaded on my harddrive to develop. Some one else in my office has 5.? loaded on his computer. When we run, we are getting different messages. I believe the difference is because the older version does not have very descriptive error messages. I could be wrong, though. Both messages are below as are parts of the code from the program doing the calling and the one being called.
I am desparate! I'm on a very tight deadline and would greatly appreciate any help at all!!!!! Thanks. Mieko

Answer 1

Well, his error says it cannot find the IDispatcher class, which probably means there's a whole bunch more it can't find.
This package jp.ne.so_net.ga2.no_ji.jcom, where does it exist? Is it a .jar file somewhere, or is it in a directory structure under your root?
You may also want to navigate (on your machine) to:
<%TOMCAT_HOME%>/work/Catalina/localhost/<%Context%>/<%path%>/select_action_jsp.java and look at line 149. You'll find the culprit there.
(Tomcat Home is where you installed Tomcat, Context is the Context name for your application, and Path is the series of subdirectories that get you to wherever select_action.jsp is)
