Migrating applications to use data sources of the current Java EE Connector Architecture (JCA)

Migrate the applications that use Version 4 data sources, or data sources (WebSphere Application Server V4), to use data sources that support more advanced connection management features, such as connection sharing. To use the connection management infrastructure in the application server, you must package the application as a Java EE 1.3 or later application. This process involves repackaging the web modules to the 2.3 specification and custom EJB modules to the 2.1 specification before installing them onto WAS.
