Hi everyone,

I'm wondering if anyone made Spring with JPA work on Websphere app server community edition 2.1..

Here's my problem: I created a JPA DAO for for the example app created in tutorial series here and here.

Everything seems to be set up right, but when I deploy the application, I keep running into the following exception.
Code:
2009-06-02 07:35:52,975 ERROR [[/contact]] Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

etc...
Here is my data layer spring config

	</bean>
	
</beans>
Am I missing something here or is it WASCE related issue?
Thanks for any info
