当客户端代码中使用RequestContext接口时，java GWT应用程序在运行时崩溃
我已经为这个问题争论了三天，我想StackOverflow是我最后的选择。我想不出为什么它不起作用了：（我正在使用GWT2.4.0和JDK1.6
我当时正在经历this tutorial并被GWT应用程序的崩溃所困扰。如果我提到com，应用程序就会崩溃。谷歌。网状物装订厂。工厂。共享。客户端代码中的RequestContext接口。我甚至不用它。我只是有一个未使用的方法，它将RequestContext作为参数。我试着引用RequestFactory——同样的例外。所以我怀疑我遗漏了一些与RequestFactory软件包有关的东西。我在GWT编译器中添加了-logLevel DEBUG，下面是我所拥有的：

完整日志是here。我的申请很小。这是我的GWT XML文件
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.0//EN" "http://google-web-toolkit.googlecode.com/svn/releases/2.0/distro-source/core/src/gwt-module.dtd">
<module rename-to="courierApp">
<inherits name='com.google.gwt.user.User'/>
<inherits name="com.google.web.bindery.requestfactory.RequestFactory"/>
<source path="client"/>
<entry-point class='com.vsezavtra.courierApp.client.courierApp'/>
</module>
主要入门课程：
package com.vsezavtra.courierApp.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootLayoutPanel;
public class courierApp implements EntryPoint
{
public void onModuleLoad()
{
RootLayoutPanel.get().add(new ManagerShell());
}
}
可绑定UI类
package com.vsezavtra.courierApp.client;
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;
import com.google.web.bindery.requestfactory.shared.RequestContext;
public class ManagerShell extends Composite
{
interface ManagerShellUiBinder extends UiBinder<Widget, ManagerShell>
{
}
private static ManagerShellUiBinder uiBinder = GWT.create(ManagerShellUiBinder.class);
public ManagerShell()
{
initWidget(uiBinder.createAndBindUi(this));
}
// if I remove this method everything works :(
public void SetTest(RequestContext test) {}
}
以及相应的XML文件
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'>
<g:VerticalPanel>
<g:HTMLPanel>
Test!
</g:HTMLPanel>
<g:HTMLPanel>
Test2!
</g:HTMLPanel>
</g:VerticalPanel>
</ui:UiBinder>
最后是我的网络。xml文件只有根“web app”元素，因为我还没有服务器端部分
我正在使用IntelliJ IDEA 10.5.2调试应用程序
如果你还有其他问题，请告诉我。我真的不知道我还能做什么：(
# 1 楼答案
看来您缺少了一个javax。RequestFactory依赖的验证实现：
在布线部分的RequestFactory教程中，建议使用hibernate validator以及其他几个依赖项：
