To use the connection management infrastructure in WebSphere Application Server Version 6.0, package your application as a J2EE 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.

In WebSphere Application Server Version 6.0.x, data sources are intended for use within J2EE applications and designed to operate within the EJB and Web containers.
