I created simple Vaadin Enterprise application(EJB3) using Netbeans 6.8, if I run that project using Glassfish V3, below exception happen. Below show my code.


Web.xml

MyApplication.java


import com.vaadin.Application;
import com.vaadin.ui.*;
/**

 * @version 
 */

public class MyApplication extends Application {

    @Override
    public void init() {
	Window mainWindow = new Window("MyApplication");
        Label label = new Label("Hello Vaadin user");
	mainWindow.addComponent(label);
	setMainWindow(mainWindow);
    }

}

This is only code I wrote.

exception

javax.servlet.ServletException: Failed to load application class: com.example.vaadin.MyApplication

note The full stack traces of the exception and its root causes are available in the GlassFish v3 logs.

If I run this same code using GlassFish V2.1 it Run perfectly, Why I can’t run it GlassFish V3 Please explain how to correct this problem.

Note - If I run web application separately using Glassfish V3 or V2.1 it work, I developed application using j2ee 5

This is a bug in the Glassfish v3 classloader.

There is a partial workaround in Vaadin 6.2.1 (see e.g.
this forum post
), but it does not cover all cases. Glassfish v3.1 nightly builds include a fix to the issue.

Thanks for reply.
That mean I can’t use GlassFish V3 to run vaadin enterprise application. So in order to run that application I have to use Glassfish v3.1 or GlassFish V3.
 Please Confirm this is true or false.

I did same example using J2ee6 and Glassfish V3. It worked perfectly below show that code


package helloworld;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServletRequest;

import com.vaadin.Application;
import com.vaadin.terminal.gwt.server.AbstractApplicationServlet;
import com.vaadin.ui.*;

public class HelloWorldApp extends Application {

	@WebServlet(urlPatterns="/*")
	public static class Servlet extends AbstractApplicationServlet {

		@Override
		protected Class<? extends Application> getApplicationClass() {
			return HelloWorldApp.class;
		}

		@Override
		protected Application getNewApplication(HttpServletRequest request) throws ServletException {
			return new HelloWorldApp();
		}
	}

	@Override
	public void init() {
		Window mainWindow = new Window("Hello World Application");
		Label label = new Label("Greetings, Vaadin user!");
		mainWindow.addComponent(label);
		setMainWindow(mainWindow);
	}
}

Please give some comments.

It is probably sufficient as a workaround to include your client side code and the gwt-user.jar in the WAR you deploy on GlassFish.

Another alternative would be to use Vaadin 6.1.x, which is not impacted by the GlassFish bug - the bug causes problems with the new widgetset packaging and composition mechanism.

Below show my project structure.

I used gwt-user.jar and glassfish v3.1 but same exception happen. I think this this problem related to this link http://vaadin.com/forum/-/message_boards/message/17184 It also didn’t have answer.

Note ;- I have set the
relative URL
 of the Main Enterprise application(Hooo) like “/vaadin” .
If i not setted it runs the index.jsp page in the Web Application module(Hooo.war)

I post my question skype chat yesterday, I got below answers


henri.sara:
The classloader of the ApplicationServlet class is unable to load your application class - this looks like some kind of a classpath issue, but I cannot really say much more Does it work if instead of using ApplicationServlet, you subclass AbstractApplicationServlet?

public Class<? extends Application> getApplicationClass() { return HooApplication.class; }
public Application getNewApplication(HttpServletRequest request) { return new HooApplication(); }

samiekblad:
[/b] As Henri said. But I the line numbers do not match to 6.4: http://dev.vaadin.com/browser/versions/6.4/src/com/vaadin/terminal/gwt/server/ApplicationServlet.java)
ah… thats because of the generated headers I suppose.
ClassNotFoundException at line 58 in this src

Using above help I modified my code like below

create new servelt



package web;

import com.example.hoo.HooApplication;
import com.vaadin.Application;
import com.vaadin.terminal.gwt.server.ApplicationServlet;
import javax.servlet.http.HttpServletRequest;

/**
 *
 * @author dinesh
 */
public class Test extends ApplicationServlet {

  
    @Override
    public Class<? extends Application> getApplicationClass() {
        return HooApplication.class;
    }

    @Override
    public Application getNewApplication(HttpServletRequest request) {
        return new HooApplication();
    }   
}

edit my web.xml


<servlet-class>com.vaadin.terminal.gwt.server.ApplicationServlet</servlet-class> 
to this
<servlet-class>web.Test</servlet-class>

Using that i can run my ejb3 application in glassfish v3,

I’m going to use above code to develop my banking application, Is it good to use above code ?

please give you’re precious comments.

Thank You.

I have the same problem but the sub-classing didn’t work, any other work around?

Thanks.

Michael.

This is a very old thread, and both Vaadin and GlassFish have evolved since then. I believe your problem might be somewhat different from the original one.

Posting a more detailed description of what you are trying to do, what happens and the exact version numbers of GlassFish and Vaadin might help.
