Hi Naresh- I don't have a Windows machine at hand (as you can imagine most of us don't use Windows) to try and replicate your issue, but Clebert and Andy have - perhaps they can try and replicate it. Regarding the JCA config - there's a chapter in the user manual on how to configure this, also there should be a fully working example in the distro that demonstrates an MDB in action. Andy is currently rewriting the JCA chapter (since it's a bit terse) so should be able to help you out with your config.
