Yes, but I mean the java class itself.

What is your implementation of that?
I just wanted to see if you are displaying it correctly.

hummm.

yes, it is a simple start sample... :(

javacode:

package biblioteca.client;

import com.extjs.gxt.ui.client.event.ButtonEvent;
import com.extjs.gxt.ui.client.event.SelectionListener;
import com.extjs.gxt.ui.client.widget.MessageBox;
import com.extjs.gxt.ui.client.widget.button.Button;
import com.extjs.gxt.ui.client.widget.button.ButtonBar;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;

/**
* Entry point classes define <code>onModuleLoad()</code>.
*/
public class App implements EntryPoint {
@Override
public void onModuleLoad() {
ButtonBar bar = new ButtonBar();
bar.add(new Button("Click-me", new SelectionListener<ButtonEvent>() {

@Override
public void componentSelected(ButtonEvent ce) {
MessageBox.confirm("Demo", "GXt is realy good", null);
}
}));
RootPanel.get().add(bar);
MessageBox.confirm("Demo", "GXt is realy good", null);
}
/**
* The message displayed to the user when the server cannot be reached or
* returns an error.
*/

}

You are using

<link rel="stylesheet" type="text/css" href="resources/css/gxt-all.css" />

This resources folder is in your war folder?

I cannot notice any problem in your code...

Are you sure you are using GWT 1.6 or 1.7?
Are you sure gxt.jar is in your classpath?

I pasted your code into my "onModuleLoad" and it worked without problems.

I think that the problem could be there:

<link rel="stylesheet" type="text/css" href="resources/css/gxt-all.css" />

Are you sure you have the css-file located there?

../biblioteca.app/war/resources/css/gxt-all.css

It worked for me too.

One thing I noticed in your HTML is that you don't include the [module].nocache.js generated file.

For example


<script type="text/javascript" language="javascript" src="gxt.nocache.js"></script>


Keep in mind that you can always troubleshoot this using Firebug
