Not able to run GWT Application

[rad]

Hi,
I've Eclipse 3.4 and I've installed GWT Designer and I'm able to create the Login Manager without any issues. Howver when I try to run it as GWT Application, I get the following error on the console:

Port 127.0.0.1:8888 is already is use; you probably still have another session active

When I click on Run as GWT Application, it opens up a GWT Development Mode page with two tabs, Development Mode and Jetty and it has a StartUp URL with default value 'Computing' and after a few seconds, it gives Module Load Failure error

Sounds like it was already running and had not been closed yet.

I'm still facing this issue and I don't see the port in use by anything else. What is the difference between the Run mode and the Test/Preview mode (in design tab). I'm able to run in Test/Preview mode but my rpc calls don't seem to work in this mode.

I'm attaching the screen shot of the error. Any help is greatly appreciated.

Thanks.

Unfortunately, those screen shots don't mean anything to me. Send a complete test case, if you want us to look into this for you.

Run mode is GWT hosted mode / development mode (design time = false).

Test/Preview is just a quick simulation showing the various widgets in your app and their resizing behavior (design time = true). Your RPC code won't work in this mode and should not be run.

In case of a Mac (OSX) I found a way to see what process occupies a port by running this command in the console:

lsof | grep ddi-tcp

In my case this returns a line such as:

java 2851 gunnarforsgren 50u IPv6 0x076980e0 0t0 TCP [::127.0.0.1]:ddi-tcp-1 (LISTEN)

In this case by killing process 2851 I can free the port:

kill 2851

Good to know.
