openejb embedded container cannot find persistence.xml

I am using openEjb in embedded mode to test a stateless session bean, which has an injected EntityManager. However, when I run the test, it fails because it could not initialize the application. When I see the console I can also see an error related to not being able to find persistence.xml Note: I tried putting WebContent, as well as META-INF in the classpath, but that does not help either. Update: There is something very strange about resource lookups when using openejb + eclipse. - I added WebContent to source folders. I stopped getting the persistence.xml error, but now I get an error which suggests that openejb could not find any managed resource - I added WebContent to source folders, but with a different output folder (using allow output folders for source folders), and the persistence.xml error starts occuring again - I copied META-INF into 'test', which is the source folder for all tests, and everything runs fine - Regarding points 1, and 2, teh issue seems to be the fact that WEB-INF also gets included as part of WebContent. If I exclude WEB-INF, then again openejb can find persistence.xml in the test and the test runs fine I am honestly clueless about what is happening. I am pasting all the relevant errors and code below.
