Portlet Producer WAR Deployment Problem

Question

Hi All,
Newbie here..
I posted this question on the other forum but nobody answered. I'd like to try it here in the Webcenter page since I am trying to create a portlet for my webcenter.
I created a very simple Portlet Producer Application. It is some sort of a hello world application.
When I am trying to deploy my war file into the integrated Weblogic server, I am encountering below error on the deployment tab.
[01:35:16 PM] [Deployer:149192]Operation 'deploy' on application 'HelloWorldPortlet' is in progress on 'DefaultServer'

[01:35:17 PM] Remote deployment failed (oracle.jdevimpl.deploy.common.Jsr88RemoteDeployer)I am particularly not sure, what persistence-config file is the deployment module looking for.
Please kindly help. Thanks
