java.lang.ClassCastException
After I got the portlet setup, I am running into a ClassCastException. I
was basically mimic the configs from the jpetstore. What this
complaining. Sorry abusing the kind helps. I just try to get the stuff
working. I am trying both jsf bridge and struts bridge. That's why you
saw different questions. Thanks a lot for your help. Yiguang

Re: java.lang.ClassCastException
Posted by Aaron Evans <aa...@gmail.com>.
My only suggestion is to check the contents of your WEB-INF/lib
directory closely against that of the jpetstore example as they relate
to struts, portlets and the bridge.
