I am new to Guice and wanted to use it on the Serverside. I am using
GWT plugin with Eclipse, which nicely creates a GWT project i.e. with
greeting service. Can anybody provide the changes I need to do to
make that a GUICE enabled project? I know that I need to inject the
GuiceModule to this code later !
What is wrong on the following changes: [The code cann't reach the
welcome html page]
_______
web.xml
___________________________________________________________
<web-app>
<!-- Servlets -->
<servlet>
<servlet-name>greetServlet</servlet-name>
<servlet-class>com.mycompany.server.MyDispatcher</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>greetServlet</servlet-name>
<url-pattern>greet</url-pattern>
</servlet-mapping>
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>GuiceWeb.html</welcome-file>
</welcome-file-list>
</web-app>

MyDispatcher.java
__________________________________________________________________________
public class MyDispathcer extends RemoteServiceServlet {
@Override
public String processCall(String payload) throws
SerializationException {
RPCRequest request = RPC.decodeRequest(payload);
java.lang.reflect.Method method = request.getMethod(); //
request.getMethod();
System.out.println(method.getName());
// Object targetInjectedInstance = injector.getInstance(method
// .getDeclaringClass());
Object targetInjectedInstance = new GreetingServiceImpl();
return RPC.invokeAndEncodeResponse(targetInjectedInstance,
method,
request.getParameters());
}
}

@RemoteServiceRelativePath("greet")
public interface GreetingService extends RemoteService {
String greetServer(String name);
}

GreetingServiceImpl [no changes here:]
______________________________
public class GreetingServiceImpl extends RemoteServiceServlet
implements
GreetingService {
public String greetServer(String input) {
String serverInfo = getServletContext().getServerInfo();
String userAgent =
getThreadLocalRequest().getHeader("User-Agent");
return "Hello, " + input + "!<br><br>I am running " + serverInfo
+ ".<br><br>It looks like you are using:<br>" +
userAgent;
}
}
Thanks
