I am following the guide here
http://cwiki.apache.org/S2WIKI/struts-2-spring-2-jpa-ajax.html
For some reason when trying to map a method other than execute I recieve
the following error:
- Servlet.service() for servlet default threw exception
java.lang.NoSuchMethodException: $Proxy18.find()
Below are the configuration files and a segment of the UserAction class.
