Running on a hosted mode, I got the following error:
"No source code is available for type
com.google.gwt.junit.client.GWTTestCase; did you forget to inherit a
required module?"
on the following code:
public String getModuleName() {
return "com.Foo"; // the error is pointing
to this line.
}
I then added to my foo.gwt.xml the following:
<inherits name='com.google.gwt.junit.JUnit'/>
Then, I ran the hosted mode again. Now it gives me the errors on
Reference [1] and [2] below.
Then, I added
<servlet>
<servlet-name>jUnitHostImpl</servlet-name>
<servlet-class>com.google.gwt.junit.server.JUnitHostImpl</servlet-
class>
</servlet>
<servlet-mapping>
<servlet-name>jUnitHostImpl</servlet-name>
<url-pattern>/foo/jUnitHost</url-pattern>
</servlet-mapping>
Now, I got the following error: "HTTP ERROR: 503; SERVICE_UNAVAILABLE"
and error Reference [3] below.
My environments: GAE 1.25, GWT 1.7, Eclipse-galileo on Windows Vista.
Thanks in advance for your help.

[1] See
file:///D:/download/eclipse-galileo/plugins/com.google.gwt.eclipse.sdkbundle.win32_1.7.0.v200907291526/gwt-windows-1.7.0/doc/helpInfo/servletMappings.html
which contains the following: "GWT modules may declare one or more
<servlet> tags. These define Java Servlets that implement the server-
side component of a GWT-enabled web application.
Prior to GWT 1.6, these GWT module servlet tags controlled the set of
servlets were actually instantiated during hosted mode. But as of GWT
1.6, this is no longer true. Instead, the web application's WEB-INF/
web.xml configuration file controls what servlets are instantiated. A
GWT module specifies only what servlets are expected.
During hosted mode startup, the set of expected servlets (from GWT
module <servlet> tags) is validated against the set of actual servlets
(from the WEB-INF/web.xml) and a warning is issued for each expected
servlet which does not match an actual servlet. "
[2] Module declares a servlet class
'com.google.gwt.junit.server.JUnitHostImpl'; but web.xml has no
corresponding declaration; please add the following lines to your
web.xml: <servlet>
<servlet-name>jUnitHostImpl</servlet-name>
<servlet-class>com.google.gwt.junit.server.JUnitHostImpl</servlet-
class>
</servlet>
