Spring2-JPA on tomcat-6, Oracle-XE, toplink

I try to upgrade a jsf application on tomcat. It was compiled but stuck at Spring JPA configuration. Any suggestion?

Environment: jdk-1.6U2, tomcat-6.0.13, jsf-1.2, myfaces-1.2.0, trinidad-1.2.1, facelets-1.1.11, Shale-1.0.4, Spring-2.0.5, toplink-2.41, Oracle-XE. More details are in the enclosed txt file.

Thanks

I found the problem while looking at the old post. The stack-overflow error is due to old xerces version. Use the following version will solve the probem.
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.8.1</version>
</dependency>

Thanks
