I inserted the code to print the context path and content type and both
display perfectly when the page is loaded.  However I still get a null
pointer and it happens in the call to the constructor of
P2K6AppPageAdminCtl:
System.out.println("Acco = " + UtilsBean.getdate());
System.out.println("context path = " + request.getContextPath());
System.out.println("content type = " + response.getContentType());
  portal = new P2K6AppPageAdminCtl(request, response);%>

I have System.out debug messages at the top of the controller, but that
never gets printed on the geronimo console.

Also this application is working perfectly when deployed in weblogic 8.1,
but we want to move it to geronimo to test it and I get this error.

Any inputs on how to proceed will be much appreciated.  Thanks for your
input so far.

Best regards,
Manisha
