I am rather new to GWT and I'm attempting to get RPC working. I am
getting the following error:

I don't know where my error is but I know when I make my rpc call, it
always fails, the error is thrown at the line onFailure(Throwable
caught). Here is my .gwt.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='reportgeneration'>
<!-- Inherit the core gwt stuff -->
<inherits name='com.google.gwt.user.User'/>
<!-- Inherit the default GWT style sheet. You can change -->
<!-- the theme of your GWT application by uncommenting -->
<!-- any one of the following lines. -->
<inherits name='com.google.gwt.user.theme.standard.Standard'/>
<!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> -->
<!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/> -->
<!-- Other module inherits -->
<!-- Specify the entry point for the class -->
<entry-point class='com.gwt.ReportGeneration.client.ReportGeneration'/
>
<!-- Specify the paths for translatable code -->
<source path='client'/>
<source path='shared'/>
</module>
and this is what my web.xml file looks like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>ReportGeneration.html</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>repGenSvcImpl</servlet-name>
<servlet-
class>com.gwt.ReportGeneration.server.ReportGenerationServiceImpl</
servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>repGenSvcImpl</servlet-name>
<url-pattern>/reportgeneration/report</url-pattern>
</servlet-mapping>
</web-app>
Any help is greatly appreciated.
