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

Migrate your 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.

About this task

To use the connection management infrastructure in the application server, you must package your application as a Java EE 1.3 or later application. This process involves repackaging your web modules to the 2.3 specification and your EJB modules to the 2.1 specification before installing them onto WebSphere Application Server.

Applications left at the Java EE 1.2 level will continue to run fine using the connection management support that was available at V4.0; simply create the JDBC provider and data source, and install the 4.0 application as-is. If you choose to repackage your application for version 6.0 or above you can not use a Version 4.0 data source. You must use the other data source option, which supports applications coded to the Java EE 1.3 specifications, at minimum.
