DBAdapter not working in SOA 11g

Question

Hi All,
I created a simple composite to insert a row in database table. However, it 's failing. I have set up the weblogic server per the following link: http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10231/life_cycle.htm#BABJFGGF - the datasource tests successfully in the weblogic console.
Any idea what is causing the error?
Non Recoverable System Fault :
Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'insert' failed due to: Could not create/access the TopLink Session. This session is used to connect to the datastore. Caused by javax.resource.spi.InvalidPropertyException: Missing Property Exception. Missing Property: [DBManagedConnectionFactory.userName]. You may have set a property (in _db.jca) which requires another property to be set also. Make sure the property is set in the interaction (activation) spec by editing its definition in _db.jca. . ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
Thanks.

I'm getting the same error, but restarting is not helping. Have deployed my connection pool and followed all the advice. Error I get is:
Exactly where and how do I set this property?
