I want to share common functionality between a couple of gwt projects
in eclipse (gwt 1.6). More precisely, I have a RPC service called
DatabaseService that handles SQL database operations. To use it in
different projects, I created a new gwt project in eclipse, called it
Services and put the DatabaseService.java and
DatabaseServiceAsync.java in the myproject.client package and the
DatabaseServiceImpl in the myproject.server package.
Then, I added that services project to another project's build path
(let's call the other project index) and added the following line to
the Index.gwt.xml <inherits name='myproject.Services'/>. The packages
in the index project are called com.is.client and com.is.server.
The access from the classes in the com.is.client package to the
classes in the myproject.client package works fine, however, when I
try to call the RPC service in the myproject.server package from a
class in the com.is.client package, I get an HTTP 404 not found error
(com.google.gwt.user.client.rpc.StatusCodeException). When I read
through the error message, I recognized that the request URI is /index/
DatabaseService, but I think, it actually should be /services/
DatabaseService. However, I did not find a way to change that.
Here are the XML files:
In the index project:
Index.gwt.xml:
<module rename-to='index'>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.user.theme.standard.Standard'/>
<!-- Other module inherits -->
<inherits name='myproject.Services'/>
<!-- Specify the app entry point class. -->
<entry-point class='com.is.client.Index'/>
</module>
web.xml:
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>Index.html</welcome-file>
</welcome-file-list>
In the services project:
Services.gwt.xml:
<module rename-to='services'>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<!-- Specify the app entry point class. -->
<entry-point class='myproject.client.Services'/>
</module>
web.xml:
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>Services.html</welcome-file>
</welcome-file-list>
<!-- Servlets -->
<servlet>
<servlet-name>DatabaseServiceImpl</servlet-name>
<servlet-class>myproject.server.DatabaseServiceImpl</servlet-
class>
</servlet>
<servlet-mapping>
<servlet-name>DatabaseServiceImpl</servlet-name>
<url-pattern>/services/DatabaseService</url-pattern>
</servlet-mapping>
</web-app>
I also tried putting the servlet name and import in the index
project's web.xml file as well, but no change.
I hope, someone can help me, I really can't find out, what I did
wrong.
Cheers!
Marcel
