Spring+multiple gwt servlets - spring

Question

1.From searching the web i understand that to use spring with gwt i would have to replace the default DispatcherServlet with org.spring4gwt.server.SpringGwtRemoteServiceServlet . But all the geomajas ( which uses spring + gwt ) examples i have seen use in fact the supposed-to-be-replaced DispatcherServlet. How could i do that too? .

What modifications must i make to the above file so that i can add another spring managed servlet ?

Answer 1

Here is how I integrated Spring with GWT via |SpringGwtRemoteServiceServlet:
Inweb.xml`:
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatch</servlet-name>
<servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>dispatch</servlet-name>
<url-pattern>/dispatch/*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>springGwtRemoteServiceServlet</servlet-name>
<servlet-class>org.spring4gwt.server.SpringGwtRemoteServiceServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springGwtRemoteServiceServlet</servlet-name>
<url-pattern>/nameOfYourApp/springGwtServices/*</url-pattern>
</servlet-mapping>
Than, whenever you wish to define a Spring managed service, use springGwtServices in the RemoteServiceRelativePath:
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import com.google.gwt.user.client.rpc.RemoteService;
#RemoteServiceRelativePath("springGwtServices/userService")
public interface UserService extends RemoteService{
}
For an implementation example:
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
#Service("userService")
public class UserServiceImpl extends RemoteServiceServlet implements UserService{
}
I hope this is what you needed
