Most likely you'll need to have your module inherit from the DOM
module. Add this line to your "module".gwt.xml file

<inherits name="com.google.gwt.user.DOM"/>

hi,Justin,thanks for you reply!

i add the line to my xml file like this,but error still exist
<module>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.user.DOM'/>
<!-- Specify the app entry point class. -->
<entry-point class='com.linzhang.client.mycard1'/>
</module>

Did you add the gwt-user.jar to your lauch classpath?

Dominik

[yummy]

yes i did it,<classpathentry kind="lib"
path="D:/gwt-windows-1.2.22/gwt-user.jar"/>
and i add "D:/gwt-windows-1.2.22/gwt-user.jar"to system classpath but
the same result
when i use projcetcreator and applicationcreator to create elcipse
project,the first can run success
but do some change like import dom package it report error ,sigh!

[dominik_steiner]

Hi yummy,

so did you actually create your project and application through the
projectcreator and applicationcreator?

I just tried it out and it works just fine, without having to inherit
any DOM package.
I just did

projectCreator.cmd -eclipse test -out ..

That created the project 'test'. And then I created the application
like this

applicationCreator.cmd -eclipse test -out .. com.bar.client.Test

That's it. I launched it through the Test-shell.cmd or the launch
configuration in eclipse.

But perhaps your problem is of another kind.

[yummy]

i create the project same with your method,this my code
package com.linzhang.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.ClickListener;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.Widget;

/**
* Entry point classes define <code>onModuleLoad()</code>.
*/
public class mycard1 implements EntryPoint {

/**
* This is the entry point method.
*/
public void onModuleLoad() {
final Button button = new Button("Click me");
final Label label = new Label();

button.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
System.out.println("hello");

}
});

// Assume that the host HTML has elements defined whose
// IDs are "slot1", "slot2". In a real app, you probably would not
want
// to hard-code IDs. Instead, you could, for example, search for
all
// elements with a particular CSS class and replace them with
widgets.
//
RootPanel.get("slot1").add(button);
RootPanel.get("slot2").add(label);
}
}

when i run it it report:

i think the gwt maybe crazy in my computer,god

[dominik_steiner]

Hi yummy,

i see that you are working wth gwt 1.2.22. did you try it with gwt
1.1.10?

but i must admit that i have no idea why you get those strange
errors...

i would try and download the gwt1.1.10 and have a fresh go with that...

Dominik

[Dan Morrill]

Hello, yummy!

You should double-check your various classpaths. (In particular, be very careful if you have "." on your classpath.) The insertListItem method appeared in GWT 1.2.22, and was not present in 1.1.10 .  I think you may have multiple versions of the GWT libraries on your classpath, and it's mixing class implementations, which is causing the error.

Let us know if that works!

i really use 1.2.22 and i change to 1.1.10 and run it successly
found some bug when use cmd to creater eclipse project,in eclipse it
reports error
but when use command to complied and run it ,it run so ok!
thanks for everyone for help me!

[aibo]

thanks for these reply.
i use Eclipse3.2.1 with Instantiations Designer , open "window -
Preferences - Designer - GWT " , uncheck "Use patch for gwt-user.jar to
fix bugs in UI classes" , then it is OK.
