Autowiring of Spring Data Repo fails with Maven Skinny war option

Question

My question is similar to this one posted a while ago The autowiring of Spring Data Repos fail when the external libraries are in EAR's lib folder.

The wiring works fine when all jars are included in WEB-INF/lib. I tried setting the 'skinnyWar' to false but this is duplicating the jars in both EAR and WAR.

The application uses Spring Batch Admin 1.2.2 and Spring Data 1.1 with Spring 3.2.2 based. Maven Version used is 3.3. The runtime is Websphere 7.x

I have another application that works perfectly fine with skinnywar set to true - this uses spring-ws, spring-data 4.0.x version.

Update: Since the EAR has only one Web module, used 'Single class loader for application' for 'WAR class loader policy' in the Websphere. This way, I am able to make this work.

I would like to know how to make this work without changing the classloader option as this might not be preferred when multiple web modules are present.
