Hi

I'm having problem importing and run the gwtrpc-spring's example.

Here are the steps I performed:

1) Download http://gwtrpc-spring.googlecode.com/files/GwtRpcSpringExample.zip

and extract the file to C:\GwtRpcSpringExample

2) Open Eclipse 3.4.2 (with Google Plugin 1.0.1)

3) Import the project by selecting File->New->Java Project

Create project from existing source (Directory: C:\GwtRpcSpringExample)

4) Enable the GWT SDK by right click GwtRpcSpringExample project, select Google->Web Toolkit Settings

then, check the Use Google Web Toolkit box and click OK.

5) When run from Eclipse, it causes the following error:

HTTP ERROR: 404

NOT_FOUND

RequestURI=/GwtRpcSpringExample.html

Well, I'm not sure if this could be the problem of the gwtrpc-spring example :-)

Are any errors being logged to the GWT Hosted Mode main window?
