This message was caused by a J2EE 1.2 Application with
Servlet 2.2 that was trying to access a database using a new IBM WebSphere
Application Server version 5 data source.
There are restrictions on what release applications can use version 5 or
version 4 data sources in WebSphere Application Server V5.0 (any
modification level).
A good explanation is located in the WebSphere Application Server V5.0
Information Center:

topic=/com.ibm.wasee.doc/info/ee/ae/cdat_datasor.html
Here is the relevant text:
