Hi all

I am learning GWT

i am tryin RPC
previously with one AsyncInterface my Project was working fine but today, after some changes and adding  async classcall is not executed. The exception is "This application is out of date, please click the refresh button on your browser." all other async calls are executed.

 

My GWT Project was working fine but today, after some changes and adding new fetures one
async call is not executed. The exception is "This application is out
of date, please click the refresh button on your browser." all other
async calls are executed.

     An IncompatibleRemoteServiceException was thrown while processing this call.
     com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: This application is out of date, please click the refresh button on your browser. ( Blocked attempt to access interface 'com.client.FInterface', which is not implemented by 'com.server.FServiceImpl'; this is either misconfiguration or a hack attempt )
 at com.google.gwt.user.server.rpc.RPC.decodeRequest(RPC.java:252)
 at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:206)
 at com.google.gwt.user.server.rpc.RemoteServiceServlet.processPost(RemoteServiceServlet.java:248)

Client :

         public void onClick(ClickEvent event) {
    
        fService.getRepositories(repocallback);
    
   }
  });

Interface

       @RemoteServiceRelativePath("init")
      public interface FInterface extends RemoteService{ 
  
  FCollection getRepositories();
     }

AsyncInterface

      public interface FInterfaceAsync {
 void getRepositories(AsyncCallback<FCollection> repositoryCallback);
 }
Service

       public class FService implements FInterfaceAsync {
 FInterfaceAsync service =(FInterfaceAsync)GWT.create(FInterface.class);
 ServiceDefTarget endpoint = (ServiceDefTarget) service;
 
     public FService(){
  endpoint.setServiceEntryPoint(GWT.getModuleBaseURL() + "init");
      }
            }

Server

     public class FServiceImpl extends RemoteServiceServlet implements  FInterface {
    
           public FilnetFolderCollection getRepositories() {
           }
 
     }
 

XML :

       <servlet>
       <servlet-name>FServlet</servlet-name>
      <servlet-class>com.server.FServiceImpl</servlet-class>
      </servlet>
 
      <servlet-mapping>
      <servlet-name>FServlet</servlet-name>
      <url-pattern>/FServiceImpl</url-pattern>
      </servlet-mapping>

 

 

Somebody help me to fix this problem.

 

Thanks
