Hi all !
I'm having some problems with the communication client-server, i just
have to submit a form but I read it's better to use RPC so I've
deleted all the reference of FormPanel and trying to do it calling a
server, but it doesn't work :(
Am I supposed to pass all the fields of the form through the method of
the ServiceInterfaceAsync?
Up to now I'm trying to pass tha "name" field as a String parameter in
that method, but I always get back the "onFailure" result.
I think I configured everything properly but obviously I'm not sure
about it.
what url shoud I put here? -> target.setServiceEntryPoint
(GWT.getModuleBaseURL() + "/provatesina/prenota");
This is the code I have in the main GWT class, it's inside the method
"onModuleLoad":
final PrenotaServiceAsync prenotaService = (PrenotaServiceAsync)
GWT.create(PrenotaService.class);
ServiceDefTarget target = (ServiceDefTarget) prenotaService;
target.setServiceEntryPoint(GWT.getModuleBaseURL() + "/
provatesina/prenota");
submit.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
Window.alert("submitting the form");
prenotaService.prenota(nome.getText(), new
AsyncCallback <String>() {
public void onFailure(Throwable caught) {
Window.alert("RPC to prenota() failed.");
}
public void onSuccess(String result) {
lab.setText(result);
}
});
};
});
