Spring and GAE : ExceptionInInitializerError

I'm now to Spring, GAE and Java in general. I'm trying to use a web app I made for Spring and to which I added GAE support afterwards. I went through a lot of problems but now I'm stuck on this one.

I realize that my context is not initialized properly but since this is managed directly by Spring, I have no idea how to solve this. I'm not sure what information I should be giving you, so here are some important files.

From the config files I see here. Everything looks good. Exception says an Initialize error, sometime it happens where a properties file or a constructor failed to Initialize. Can you verify based on the config file here, is this

<resources mapping="/resources/**" location="/resources/" />

configured and ready to go?? I have my properties folder under src that gets compiled to the output directory.

The other thing that is in the stacktrace is DefaultListableBeanFactory exception initialization problem. Please verify if you have the correct versions of spring Jar files in your classpath.
