DEFERED结合例外GWT自定义部件到UiBinder的

我是新来GWT，寻找到UiBinder的DEFERED结合例外GWT自定义部件到UiBinder的

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"> 
    <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" 
      xmlns:g="urn:import:com.google.gwt.user.client.ui" 
      xmlns:my = "urn:import:com.kt.outdoor.media.client.view"> 

    <g:DockLayoutPanel unit='EM'> 
     <g:north size='5'> 
      <g:FlowPanel styleName="{style.northPanel}"> 
       <my:Menu ui:field="hello"></my:Menu> 
      </g:FlowPanel> 
     </g:north> 
    </g:DockLayoutPanel> 
</ui:UiBinder>`

和

package com.kt.outdoor.media.client.view; 

import com.google.gwt.core.client.GWT; 
import com.google.gwt.uibinder.client.UiBinder; 
import com.google.gwt.user.client.ui.Composite; 
import com.google.gwt.user.client.ui.Widget; 

public class Menu<T> extends Composite implements MenuView<T> { 

    private static MenuUiBinder uiBinder = GWT.create(MenuUiBinder.class); 

    interface MenuUiBinder extends UiBinder<Widget, Menu> { 
    } 

    private Presenter<T> presenter; 

    public Menu() { 
     initWidget(uiBinder.createAndBindUi(this)); 
    } 

    @Override 
    public void setPresenter(Presenter<T> presenter) { 
     this.presenter = presenter; 
} 

    public Widget asWidget() { 
     return this; 
    } 

}

的例外是

任何机构可以请告诉我我的代码有什么问题。

在此先感谢

这是演示代码，我不理解为什么它的失败。

package com.kt.outdoor.media.client.presenter; 

import com.google.gwt.event.shared.HandlerManager; 
import com.google.gwt.user.client.Window; 

import com.google.gwt.user.client.ui.HasWidgets; 
import com.kt.outdoor.media.client.event.ButtonClickEvent; 
import com.kt.outdoor.media.client.view.MenuView; 

public class MenuPresenter<String> implements Presenter, MenuView.Presenter<String>{ 


private final HandlerManager eventBus; 
private final MenuView<String> view; 

public MenuPresenter(HandlerManager eventBus, MenuView<String> view) { 

    this.eventBus = eventBus; 
    this.view = view; 

    this.view.setPresenter(this); 

} 

@Override 
public void onMenuButtonClicked() { 
    Window.alert("Hello!"); 
    eventBus.fireEvent(new ButtonClickEvent()); 

} 

@Override 
public void go(HasWidgets container) { 
    container.clear(); 
    container.add(view.asWidget()); 

} 

}

在项目中使用的任何模块/类是否不在您项目中，如外部项目或jar文件？如果是这样，你在gwt.xml文件中继承它？ – Dipak 2013-04-27 08:08:57

请添加您的演示者代码。 – Dipak 2013-04-27 08:13:02

我认为堆栈跟踪缺少一些线条，但是您是否总是需要在DockLayoutPanel中使用

元素？ – 2013-04-27 09:31:07

它是与你的项目设置。堆栈跟踪中的主要问题是，GWT编译器不会访问类为com.kt.outdoor.media.client.view.Menu的gwt.xml模块。请仔细检查您的GWT模块xml文件设置，或者更好地发布您的项目布局和gwt.xml到您的问题。

我得到了同样的问题。这是我解决它的方式。首先检查您的.gwt.xml文件中是否已经有此条目

<source path='client'/> 
<source path='shared'/>

如果已经存在，请检查您是否使用最新的xerces jar。我的问题通过从xerces/xercesImpl.jar-2.6.2更新到xercesImpl.jar得到解决 - 2.9.1
这是我在GWT编译期间遇到的错误。

 java.lang.AbstractMethodError: 
    org.apache.xerces.dom.ElementNSImpl.setUserData(Ljava/lang/ 
    String;Ljava/lang/Object;Lorg/w3c/dom/UserDataHandler;)Ljava/lang/ 
    Object; 
    at com.google.gwt.uibinder.rebind.W3cDocumentBuilder.startElement(W3cDocumentB 
uilder.java:130)

您可以从http://mojo.codehaus.org/gwt-maven-plugin/dependencies.html

下载JAR让我知道如果这个工作！
