i am facing an error in the Invoke_DB activity in the bpel
Exception occured when binding was invoked.
Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'DB_Invoke' failed due to: Could not create/access the TopLink Session.
This session is used to connect to the datastore.
Caused by java.lang.ClassCastException: oracle.tip.adapter.db.DBConnectionFactory incompatible with javax.sql.DataSource.
You may need to configure the connection settings in the deployment descriptor (i.e. DbAdapter.rar#META-INF/weblogic-ra.xml) and restart the server. This exception is considered not retriable, likely due to a modelling mistake.
The invoked JCA adapter raised a resource exception.
Please examine the above error message carefully to determine a resolution.
