Solving CoreMessageLogger NoClassDefFoundError

This problem can occur when you have a Hibernate 3.x and a Hibernate 4.x dependency in your classpath, and the Hibernate 3 dependency was first on your classpath.

Look in your Maven Dependency hierarchy to see where the Hibernate 3 / 4 dependencies come from and solve it by eg. excluding transitive dependencies in your POM.
