Glad that you found the error. I would like to add something to this

Actually most containers pool their processor threads in order to conserve and
regulate resources.
The RemoteServiceServlet in GWT simply decodes the response and invokes the
method which the request
relates to. Theres no magic or rocket science going on here. I don't know what

Also, keep in mind that the noserver option will not work with server

It doesn't sound like there's anything wrong with your deployment, it sounds
like you're trying to do something invalid. Why are you sending GET requests
to an RPC servlet?

I tried to launch the application, by navigating the browser to

That's why I added the doGet method.
