How To Configure JRun Classpath--Servlets Not Found

Question

How do I get JRun to pick up my classes in Unix? I have a WAR
application that works fine in Windows on a local copy of JRun4. If
I deploy it to Unix (making sure I haven't introduced any issues
such as ^M characters, of course), I find that my JSPs can be
picked up but the first time I attempt to access a servlet, it
turns up not found. The Servlet .class file is located in the
correct package in the WEB-INF/classes/ directory. Although I
should have been able to access it by mapping the URL in the
web.xml (which doesn't work even on the Windows copy, subject of
another question), even when I give the explicit name of the
servlet, i.e. /servlet/com.myco.myservlet.MyServlet, it is not
found.
Please explain to me what I have to do to permit my Servlets
to be picked up. I have tried putting an explicit classpath in the
startup script, i.e.: -cp
./.../servers/default/mywar/WEB-INF/classes/ but it does not make a
whit of difference. What gives? What must I do so that my classes
are picked up?
Thank you.

Hi, Guenther:
You can use <error-page> element of web.xml. Add an element to your web.xml like
<error-page>
<error-code>404</error-code>
<location>/404.jsp</location>
</error-page>
or
<error-page>
<exception-type>java.io.IOException</exception-type>
<location>/myException.html</location>
</error-page>
Both of them work when I try 10.1.2. This mechanism is a j2ee standard. You might want to search the web for "error-page" and "web.xml" or look at the j2ee specfication. Hope this helps you.
