I believe that WebSphere Application Server version 2.02 still uses jsp .91
spec. This means that you use callPage() to invoke a jsp from a servlet.
This is documented here:
http://www.software.ibm.com/webservers/appserv/doc/v20dcstd/doc/whatis/icjsp
ref.html#jspapiref.
I have been told that release 3 will have full servlet API 2.1 support which
includes the JSP 1.0 support (as well as retaining the callPage() support to
give you time for migration to request dispatcher) .
