I install the Google Plugin, the GAE SDK, and the GWT SDK per instructions.
I created a simple project, during which I found I had to manually point the Google Plugin to the GAE and GWT SDK directories (there were some previous directories, perhaps from a past installation, that no-longer existed). I told it to generate the example code (the default functionality).
So then to test the example code I right click on the project, and go to Run As -> Web Application.
In the Console I see this:
2011-03-17 22:31:20.809 java[86443:a07] [Java CocoaComponent compatibility mode]: Enabled
2011-03-17 22:31:20.813 java[86443:a07] [Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.100000

The server is running at http://localhost:8888/
It then seems to quit immediately (the red box that indicates it is running goes grey).
There is also a “Development Mode” tab which lists the following URL:
http://127.0.0.1:8888/CustLTV.html?gwt.codesvr=127.0.0.1:9997
When I click on that I’m taken to that URL, but I get “Connection refused”, nothing is listening on that port.
What am I doing wrong?
