Hi all-
I have a startup servlet which initializes a connection pool (THIS IS NOT A
DATABASE CONNECTION POOL) to a legacy system that my webapp accesses. This
servlet puts a singleton connection broker into the ServletContext and is
shared among all my servlets. The destroy() method of this servlet then
ensures that all connections in the broker object are closed. My problem
is this:
I have a class which is stored in the HttpSession of the user. This class
implements HttpSessionBindingListener and then when the session is unbound
uses the startup servlet's connection pool to do some cleaning up by
accessing the legacy system. This is fine but when I manually shutdown the
server (Tomcat 3.1), the server invalidates the user sessions but this
occurs after the destroy() method of my startup servlet is called which in
effect makes the system calls to the valueUnbound() method of my class try
and grab a resource which doesn't exist anymore in the ServletContext.
What I want to do is have the destroy() method wait until all the
HttpSession objects have been invalidated and then and only then clean up
the connection pool. I can't seem to find anyway to access any information
about server wide HttpSession's. Anyone have any ideas on how to do this??
Thanks,
Mike
