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

[dbgroups]

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
