NoClassDefFoundError using Groovy in Spring

Hi,

I am using groovy in Spring context. I am running the spring container loaded in an application server.
I have set the Thread current context class loader correctly and that context classloader is able to find groovy/lang/GroovyClassLoader.

The problem is, when Spring is creating the bean, it fails with the following exception:

Can any one suggest something? Should this question be posted to the Spring Forum instead?
