Hi,

Is there some tutorial for using Weld and Vaadin?

Thanks

Hi, Eric,

In order to run Vaadin with Weld in Tomcat I’ve written two classes

public abstract class WeldApplication extends Application {

InjectionTarget<WeldApplication> injectionTarget;
CreationalContext<WeldApplication> creationalContext;

@Override
public final void close() {
    super.close();
    injectionTarget.preDestroy(this);
    injectionTarget.dispose(this);
    creationalContext.release();
}

}

public class WeldApplicationServlet extends ApplicationServlet {

@Inject
private BeanManager beanManager;
private InjectionTarget<WeldApplication> injectionTarget;

@Override
@SuppressWarnings({"unchecked"})
public void init(ServletConfig servletConfig) throws ServletException {
    super.init(servletConfig);
    if (beanManager == null) {
        beanManager = (BeanManager) getServletContext().getAttribute(BeanManager.class.getName());
    }
    injectionTarget = (InjectionTarget<WeldApplication>)
            beanManager.createInjectionTarget(beanManager.createAnnotatedType(getApplicationClass()));
}

@Override
protected Application getNewApplication(HttpServletRequest request) throws ServletException {
    CreationalContext<WeldApplication> context = beanManager.createCreationalContext(null);
    WeldApplication application = injectionTarget.produce(context);
    injectionTarget.inject(application, context);
    injectionTarget.postConstruct(application);
    application.injectionTarget = injectionTarget;
    application.creationalContext = context;
    return application;
}

}

I have my application extending WeldApplication (the scope is default - @Dependent), and the contents of my web.xml is like the following

org.jboss.weld.environment.servlet.Listener ApplicationServlet WeldApplicationServlet application MyApplication ApplicationServlet /app/* /VAADIN/*

Cheers,
Taras

Hi!

Don’t have a tutorial to point to, but a small hint: use nightly build ( http://vaadin.com/download/nightly/6.2/ ) with glassfish 3. There is a nasty bug in glassfish 3 classloader that prevents Vaadin app to start without gwt-user jar on classpath.

6.2.1 should come out pretty soon, which will add a workaround for it.
