WLS 10.3 + hibernate: DuplicateMappingException while deploying the war file

[sankha ghosh]

Hello,

I have an application build using Spring BlazeDS integration framework (in plain english: backend Java with Spring and front end Flex). I am using Hibernate.

Previously I had jdk 1.5, BEA WLS 9.2 and the application was running fine both in eclipse integrated server or standalone server where I deployed the application.war file. I was running the server in Windows XP and Windows server 2003 based systems.

Now I need to use jdk 1.6, Oracle WLS 10.3. Initially I had the issue with Hibernate (the popular Hibernate and WLS 10.3 issue with antlr 2.7.6). My new environment is Windows 7 and Windows 2008 R2 (64 bit)

After that my eclipse integrated weblogic is able to run the application and everything is working normally. Then I exported the .war file and trying to deploy it in a standalone WLS domain admin server. This time, I am getting the following error :

weblogic.application.ModuleException: [HTTP:101216]Servlet: "****<Application>" failed to preload on startup in Web application: "****<Application>.war".
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.DuplicateMappingException: Duplicate class/entity mapping com.****<Application-Package>.beans.ADR

I unzipped the war file and found no duplicate files. There should not be any. Can anyone please help me? I am stuck at this point for few days.
