GWT & superdevmode

Hope I will find the key guy here :)

First, I am very new in gwt/java....so, please forgive me if my question in somehow malformed or out of scope.

Based on samples found in the net, I developped a gwt webapp....that's works fine (so far) when it is started in superdevmode from eclipse (through jetty). A browser can access my webpage from local/remote computer (bindaddress=0.0.0.0).

Issues are coming when trying to deploy it with TomCat. Indeed, webpage is accessible, but at some point, there is a redirection to port 9786. I guess this is a normal situation since it is built in superdevmode (unless bad asumption here). If I set the development mode in eclipse to Classic mode. It does not work even in eclipse.

From my point of view, having a web server listening on port 9786 is not a proper implementation....So, I am trying to get rid of this port (probably a matter of dev mode).

Any idea, question, remark, or whatever would be welcome....cause I am getting stucked! Obviously, I will be happy to provide more info if needed for resolution.

Txs a lot for your help.
