ClassNotFoundException during DMa launch



When launching Deployment Manager (DMa) application for the first time on weblogic 10.3.5, ClassNotFoundException is thrown. The .ear and DMa schema configuration works fine on weblogic 9.2MP3.

Error Messages

Caused By: java.lang.ClassNotFoundException: javelin.jsp.JspFunctionMapper
 at weblogic.utils.classloaders.GenericClassLoader.findLocalClass(

Steps to Reproduce

User is migrating to new hardware. The underlying database is not being altered.
Deployed the DMA application on the new server ,
Created the data source (tested successfully).
Created new SVN repository, corresponding users and tested the same (the new repository is not configured in DMA yet).
Launched the DMa application

Root Cause

DMa war file contains the pre-compiled jsp/servlets using JDK1.5


Below steps are followed:

- start weblogic server (WL) and login to admin console
- undeploy the DMa application
- stop WL managed instance
- remove "tmp" directory under <domain>\<server>

- start WL
- Open the dma_wls_ora.ear in 7-zip or winzip and then delete the jsp_servlet directory and its containing files from “dma_wls_ora.ear\dm.war\WEB-INF\classes\” . Note that jsp_servlet directory contains the pre-compiled JSP files and deletion of this folder, the weblogic will once again compiles the JSPs during the deployment.
- deploy the DMa application using the updated dma_wls_ora.ear
