Deployment error - weblogic 7.0.2 to weblogic 9.2

Question

Hello,
We have recently Upgraded our server from 7.0 to 9.2.
Our application doesnt get deployed.It throws following error.
Unable to access the selected application.
Exception in AppMerge flows' progression
We compiled our application in Eclipse using JDK 1.4
But could not compile using JDK1.5 which comes with BEA9.2
Can this be a problem.
Our ear file has 4 .war files and 34 .jar files
I tried the solutions below but nothing worked out.
Can some one suggest a solution.
Posting a section of our application.xml here below...
Pls suggest if any changes....
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE application PUBLIC '-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN' 'http://java.sun.com/dtd/application_1_3.dtd'>

Answer 1

Well,
I was able to remove this error.But struck at another one.
I will first specify what was wrong in my application.
As I said Weblogic 9.2 was not recognizing my .ear file for a deployment and throwing below error.
The problem was in my web.xml file.
I have declared a security role name twice.see below...
<security-role>
<description>Create Modify Cancel FHRB</description>
<role-name>cmcFHRB</role-name>
</security-role>
<security-role>
<description>Create Modify Cancel FSRB</description>
<role-name>cmcFHRB</role-name>
</security-role>     
After i fixed this Weblogic accepted my ear file for deployment and deployed as well.
Which was not case in Weblogic 7 (It used to deploy even with above errors)
But now when i start the services.
It doesnt start.
I tried to deploy a simple ear file but services dont get started.
wondering why its happening.Throws below error.
An error occurred during activation of changes, please see the log for details.
weblogic.application.ModuleException:
java.lang.NullPointerException:
I'll be gratefull if some one can throw some light in my eyes, instead of just reading this quote and ignoring.
thanks again very much
VJ
