Hi everyone, Im trying to use RequestFactory + Hibernate. I just started with GWT.. I hope you can help me.
Thats what i did so far: 1) I included the following in WEB-INF/libs (they are in subfolders like WEB-INF/libs/validators/.. for structuring.. hope thats no problem) validation-api-1.0.0.GA.jar (added validation-api-1.0.0.GA-sources.jar as source) hibernate-validator-4.3.0.Final.jar hibernate-validator-annotation-processor-4.3.0.Final.jar Also added them on the "Java Build Path" of my Project. 2)Added Code mentioned in the link to my web.xml https://developers.google.com/web-toolkit/doc/latest/DevGuideRequestFactory#wiring 3) Setup Validation by this Post: http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation Below I post some Code + Errors. I try to run the following code in my onModuleLoad() entry point: WorkerRequestFactory factory = GWT.create(WorkerRequestFactory.class); factory.initialize(new SimpleEventBus()); WorkerRequest request = factory.workerRequest(); WorkerProxy newWorker = request.create(WorkerProxy.class); newWorker.setFirstName("firstname_test"); newWorker.setLastName("lastname_test"); newWorker.setSalary(20000); Request<Void> createReq = request.persist().using(newWorker); * createReq.fire(new Receiver<Void>() {* @Override public void onSuccess(Void arg0) { // Update display Window.alert("OK"); } }); *createReq.fire(new Receiver<Void>()* throws the exception... If you need any further information, please let me know. Thanks for your time + help in advanced.
