Извините, я новичок в этой теме, но всегда получаю это исключение, когда хочу сделать вызов rpc:
Причина: com.google.gwt.user.client.rpc.ServiceDefTarget $ NoServiceEntryPointSpecifiedException: URL реализации сервиса не указан
Я не знаю почему, потому что я сделал это как Учебное пособие по gwt.
Вот мой исходный код:
web.xml:
<web-app>
<servlet>
<servlet-name>SpeicherService</servlet-name>
<servlet-class>de.fhdo.kuss.server.SpeicherServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>SpeicherService</servlet-name>
<url-pattern>/SpeicherService</url-pattern>
</servlet-mapping>
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>Kuss_Projekt.html</welcome-file>
</welcome-file-list>
</web-app>

Kuss_Projekt.gwt.xml:

Speicherservice:
@RemoteServiceRelativePath("SpeicherService")
public interface SpeicherService extends RemoteService {
String getName(String name);
public static class Util {
private static SpeicherServiceAsync instance;
public static SpeicherServiceAsync getInstance(){

SpeicherServiceAsync:
public interface SpeicherServiceAsync {

}
-
SpeicherServiceImpl:
public class SpeicherServiceImpl extends RemoteServiceServlet implements SpeicherService {

Test():
public void test() {
AsyncCallback<String> callback = new AsyncCallback<String>() {
@Override
public void onFailure(Throwable caught) {
// TODO Auto-generated method stub
}
@Override
public void onSuccess(String result) {
Window.alert(result);
}
};
SpeicherService.Util.getInstance().getName("test",callback);
}
