If you want to use Proxy DataSource support, you need to create the proxy datasources from the administrative console, or use the wsadmin tool. WebSphere® Extended Deployment delivers two Java Database Connectivity (JDBC) providers for Proxy DataSource support. One is called Proxy DataSource JDBC Provider, which is for connecting to non-XA-capable data sources. The other is called Proxy DataSource JDBC Provider (XA), which is for connecting to XA-capable data sources.
