Class not found in jar

Question

I have a servlet that is using request.forward() to invoke a class in a jar file.
This class is in the class path, as below. However, when that class runs, it cannot find other classes in that same jar file.
In my resin.conf file I have:
<web-app id='/test' app-dir='d:/apps/test'>
     <classpath id='d:/apps/otherApp/WEB-INF/lib/otherApp.jar'/>
</web-app>
The jar file is in the web-inf/lib folder.
Running under Resin.
What do I need to do such that the invoked class will find it's fellow classes that are in the same jar file?

Answer 1

I don't see why
you would need to add that jar to the conf file.My web-app cannot otherwise find the target class. It is part of a different 'web-app'.
how did you create the jar?I didn't. This is a third party app. I cannot disturb the jar.
Due to the third party app, there are legacy issues that I am having to work around.
So my situation is like this.
c:/apps/app1
c:/apps/app2
c:/apps/app3
So, another servlet will contact app1. Depending on the 'POST'ed data, app1 will invoke either app2 or app3.
All code for app2 is in jars in WEB-INF/lib.
