I have an application that is currently running under Tomcat 3.2, Turbine 1.x,
and WebMacro on Solaris and am looking to upgrade the application to Tomcat 4.0,
Turbine 2.2 and Velocity. I have scoured websites such as jguru.com and have
perused the mailing lists for turbine and tomcat for information that may help
identify the problem with my configuration with no luck. Scott Anderson posted
something similar back in March 2001, but I was unable to locate the complete
details of his solution (or if he got it working).
Here's what I've done so far.
1) Downloaded the TDK.
2) Built the sample 'newapp' application which runs fine.
3) Copied the complete directory tree from newapp to kss under webapps and
modified the following files/directories:
* WEB-INF/conf/TurbineResources.properties:
- to change the module.packages to include my package
(gov.nih.nlm.kss.modules)
- to locate the templates directory
- to specify my KssLogin.vm file as the login file
* lib/ directory to have all of the appropriate .jar files for my
application.
* WEB-INF/web.xml to change the name of the servlet from newapp to kss
4) I created a KssLogin.vm file and put it in the templates/screens directory
which makes a call to the action KssLogin.
5) I created a modified login action (KssLogin.java) from my application and
placed it in unpacked area (gov.nih.nlm.kss.modules.actions) in the classes
directory.
I restarted the server and my new login screen appears. When I attempt to login
and execute the KssLogin action, I get the following exception:
Horrible Exception: java.lang.ClassNotFoundException:
Requested Action not found: KssLogin
Turbine looked in the following modules.packages path:
[gov.nih.nlm.kss.modules, org.turbine.app.newapp.modules,
org.apache.turbine.modules]

The velocity.log file gives the error
"org.apache.velocity.exception.ResourceNotFoundExcept
ion: Unable to find resource 'VM_global_library.vm'" but I'm not sure that's
related to my missing class problem.
There are no other problems identified in the turbine.log file except the
Requested Action not found error.
I have verified the package structure of the KssLogin.java and that it's located
in the proper place within the classes directory structure
(gov/nih/nlm/kss/modules).
Any ideas are greatly appreciated. Thanks in advance,
Karen
