RE: Long time processing in the DwrServlet.service()

Hi Dmitry,

I would suggest you try your application in a regular servlet engine,
like f ex Tomcat or Jetty, and report back if you still have any 
problems. Reproducing your error in a "standard" environment will make
it much easier for other developers on the list to help you.

BTW: What is your impression of Simple framework? (There doesn't seem
to have been much activity the last years.)

Best regards
Mike Wilson
