Question

I installed: JDK 1.7.0_10, GWT 2.4, GXT 2.2.5, App Engine 1.7.0, Eclipse Indigo Service Release 2, Glassfish-3.1.2.2-windows-ml, WinXP SP3.

I created a new “Web Application project”. Run->Run As… -> Web application:

http://127.0.0.1:8888/Exp.html?gwt.codesvr=127.0.0.1:9997

In that case I had:

Sending name to the server:

Server replies:
Hello, GWT User!

I am running Google App Engine Development/1.7.0.

When I compiled my application and copy “war” folder into glassfish docroot: E:\glassfish3\glassfish\domains\domain1\docroot\exp\

If I try to open the link: http://localhost:8080/exp/Exp.html
I have the error:

Sending name to the server:

Server replies:
An error occurred while attempting to contact the server. 
Please check your network connection and try again.

The error is:

Just copying content to the root won’t work. Try to build war file (not sure, but application’s root could be also ok) and to place it to autodeploy folder. Here is the detailed description of deploy process. Please also check Glassfish logs, to be sure that application is deployed successfully.
