Servlet decument says: getDatasource(HTTPServletRequest) is used to get the
default datasource, getDataSource(HttpServletRequest, String) get the selected
datasource. However, since I am using struts. following instruction in tomcat
documentation on connection pooling and using getDatasource within a struts
action class give a null resource because although action class has
getDatasource(HttpServletRequest) as the httpServlet class, it only return
resource which is managed by strut not the from container as the httpServlet
object does.
I'm now letting struts manages the resource. My problem is partly solved for
now.
Thanks for your suggestion

I'm not sure what to tell you. The method getDataSource( request,
"jdbc/TestDB" ) is not a part of tomcat or the servlet spec. Is it part
of Struts?
