Migrating struts application from 10.1.2 to 10.1.3.1

Question

I've tried migrating my struts application from using JDev 10.1.2 to 10.1.3.1. When I try to open up the struts-config.xml file, I get a Java runtime exception error. I am using JDK 5.0.60.5. I'm not sure how to fix this....
Message
BME-99004: A Java runtime exception has occurred.
Cause
This exception should have been dealt with programmatically. The current activity may fail and the system may have been left in an unstable state. The following is a stack trace.

Action
If further errors occur, you should restart the application.
Also, report the problem on the JDeveloper forum on otn.oracle.com, or contact Oracle support, giving the information from this message.

Answer 1

Yes, but the application under 10.1.3 points to the application.jws file in the old 10.1.2 directory.
I want the application to point to the .jws file JDeveloperApplication/<application>/<application>.jws.
10.1.3 keeps this pointer somewhere and would like to change it. I scanned the jdev directory for files containing <application>.jws, and found it in the binary file jdev/system/oracle.jdeveloper.10.1.3.36.73/system.sys file, and the ide.properties file, and the system/oracle.ide.10.1.3.26.73/windowinglayout.xml file.
None of these files seem to be the place to make the adjustments.
I guess the more general question for me is "How should JDeveloper be configured to allow for migration of applications? (It does not seem to be a no-brainer!) How should it be configured when additional libraries have been included in the list libraries of prior JDeveloper version and need to be migrated/duplicated to a new version of JDeveloper? How are connections supposed to be migrated (for database, cvs, application servers)? How should JDeveloper be configured for team use? (Each member of a team should maintain identical JDeveloper configurations. Yes?)"
But, first things, first. How do I point a JDeveloper application to a different .jws and application directory?
