Hello --
Here is something interesting :
I have servlet A. Its doPost and doGet methods are mapped onto a
single method say processReq(). Within the process req method I
instantiate a handler class say H.
Handler class tries something and fails raising an exception. This
exception is propogated back and caught by my servlet' processReq()
method. It returns an error message back to webserver.
Pretty simple design ... but here starts the problem ..
If I check the memory profile of JRun, I see that the instance of
class H continues to be there. If you repeat the process again there
is another instance getting created ! There is (as expected) only a
single instance of servlet.
I think this is related to my first question where such a build up
finally makes the VM run out of memory. Any non-servlet classes
(external) loaded during the servlet execution are NOT getting
disposed at all.
What is going wrong ?? Anything I am missing of the servlet design
techniques ? Or is it some problem with JRun.
