The root cause is:

Caused by: java.lang.IllegalAccessError: tried to access method org.hibernate.cfg.Mappings.<init>

Based on the description of that exception (see http://download.oracle.com/javase/1.5.0/docs/api/java/lang/IllegalAccessError.html), I suspect that the Hibernate JAR being used at runtime doesn't match the one used to build Spring (since Spring code is what is accessing Hibernate).

Does your application contain Hibernate JARs? If so, then this is a classloading issue and you might have to define a classloader repository.
