Hi ,
I am new in GWT.
I am trying to develp an application using GWT+Spring .
following are application code
1) MyApplication .java
package com.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.user.client.rpc.ServiceDefTarget;
import com.google.gwt.user.client.ui.*;
// Referenced classes of package csw.client MyService, MyServiceAsync
public class MyApplication implements EntryPoint {
public MyApplication() {
}
public void onModuleLoad() {
final Label label = new Label();
final MyServiceAsync svc = (MyServiceAsync)
GWT.create(com.client.MyService.class);
ServiceDefTarget endpoint = (ServiceDefTarget) svc;
endpoint.setServiceEntryPoint("services/myService");
final AsyncCallback callback = new AsyncCallback() {
public void onSuccess(Object result) {
label.setText(result.toString());
}
public void onFailure(Throwable ex) {
label.setText(ex.toString());
}
};
Button button = new Button("Click ME");
button.addClickListener(new ClickListener() {
public void onClick(Widget w) {
svc.myMethod("Do Something", callback);
}
});
RootPanel.get("testing").add(button);
RootPanel.get("testing2").add(label);
}
}
