GWT1.7 + Spring3 intégration

Hello,

I'm trying to integrate Spring into a Gwt application (using IntelliJ
Idea) to use some beans or class located in the core package.
Here is the application's structure

I found an interresant way on http://code.google.com/p/spring4gwt/.
I followed the "simple rpc example" at this page :
http://code.google.com/p/spring4gwt/wiki/SimpleRPCExample.

Thus i added spring libraries, gwt libraries and the spring4gwt.jar to
my project and modify my files following the example.

}
});

// assemble main panel
verticalPanel.add(horizontalPanel);
verticalPanel.add(label);

// add the main panel to the HTML element with the id
"stockList"
add(verticalPanel);

// move cursor focus to the text box
textBox.setFocus(true);
}

}
[/CODE]

When I launch my application and then click on the button who call the
rpc-service I have this error:

[CODE][WARN] Resource not found: springGwtServices/crcService; (could
a file be missing from the public path or a <servlet> tag
misconfigured in module biz.manex.chbah.crc.web.CRC.gwt.xml ?)[/CODE]

Can someone help me ?

Thanks.
