The J2EE Connector Specification, Version 1.0 Final Release defines two types of credentials that resource adapters can support: password credentials and generic credentials. In the previous release of WebLogic Server, you specified your password credentials in the security-principal-map element in the weblogic-ra.xml deployment descriptor file. The security-principal-map element was provided to map between the initiating principal and resource principal. BEA also provided a Password Converter Tool for encrypting the password stored in the security-principal-map element.
The storage of user names and passwords for principal maps in weblogic-ra.xml is not the most elegant nor secure storage mechanism. As a result, the security-principal-map element and Password Converter Tool have been deprecated in this release of WebLogic Server. The principal map has been moved from the security-principal-map to an internal WebLogic Server storage mechanism (a directory server).
The J2EE Connector specification, Version 1.0 Final Release requires storage of credentials in a javax.security.auth.Subject; the credentials are passed to either the createManagedConnection() or matchManagedConnection() methods of the ManagedConnectionFactory object.
