No you haven't called run() correctly, not if you wanted it to run in
a new thread.
Take a look at http://www.westhawk.co.uk/nluug/nj96/practical.html
for a simple example.
However I'm guessing that you can get what you want without using
threads.
If you just want the hashtable cleaned up when sessions timeout (which
they
will if not used), you can just use the SessionBindingListener interface
Which will be invoked at the 'correct' times by the servlet container.
