I got the ejb / struts/ adf app at the above address working on Oracle jDev's embedded server.

I have it installed on websphere 6 point something er other as an ear file and the admin console says it is running with no problem (little green arrow).

When i point the browser to the address

http://localhost:9080/HRApplication-ViewController-context-root/browseDepartments.do

I get this error

Error 500: SRVE0207E: Uncaught initialization exception thrown by servlet

BTW

I have installed a simple a struts app that i also wrote on jDev which is non ejb (just a war file). It is working fine.

I forgot to mention that i did install the libaries (jar files) that oracle's adf requires.
