I am new in GWT and I tried to create an application on testing RPC.
It prompts 404 Error (RequestURI=sample/myService) in Host Mode of
Eclipse. Can anyone help me? Below are my codes. Thank you very much.
**************Sample.java *********************** (Client program to
call RPC)
public class Sample implements EntryPoint {
MyServiceAsync myService = (MyServiceAsync)
GWT.create(MyService.class);
ServiceDefTarget endpoint = (ServiceDefTarget) myService;
String moduleRelativeURL = GWT.getModuleBaseURL() + "myService";
endpoint.setServiceEntryPoint(moduleRelativeURL);
AsyncCallback callback = new AsyncCallback()
{
public void onSuccess (Object result)
{
success = true;
Window.alert(result.toString());
}
public void onFailure (Throwable ex)
{
calendar.setData(CalendarOverlappingData.getRecords());
Window.alert(ex.toString());
}
};
myService.myMethod("sa", "sa", callback);
}
******************* MyServiceAsync.java ****************
public interface MyServiceAsync {
void myMethod(String userName, String passWord, AsyncCallback<String>
callback)
throws IllegalArgumentException;
}
******************MyService.java ********************
@RemoteServiceRelativePath("myService")
public interface MyService extends RemoteService {
String myMethod(String name, String passWord) throws
IllegalArgumentException;
}
******************MyServiceImpl.java ********************
public class MyServiceImpl extends RemoteServiceServlet implements
MyService
{
private static final long serialVersionUID = 1L;
String success;
boolean flag=false;
public String myMethod(String userName, String passWord) {
success="OK";
return success;
}
}
