weblogic tapestry issues

My application using tapestry 4.1.6 jar files deploys correctly in weblogic 10.3.3.0. But at runtime, I am getting NoSuchMethodException from tapestry files.Same application works fine in weblogic 9. Any ideas?

Error Log

I'd check to see if WebLogic 10.3 has a conflicting Tapestry JAR at the server class loader level. If yes, you'll want to tell WebLogic to prefer the version of Tapestry that it finds using your application class loader.

See <prefer-web-inf-classes> in weblogic.xml:

Note: Weblogic is often configured by default, it filters javax.* package. (X Add J2EE libraries to buildpath)
