Java 瓦丁小部件编译

我有Vaadin 6.8.6应用程序，并使用ant构建它。现在我也想使用ant重新编译我的应用程序，但编译器并没有看到我在应用程序中实现的小部件。所以我有这样的ant构建脚本。在我的项目中，我有一些软件包

com.example.vaadinresearch
   ..ServerComponent...class
--com.example.vaadinresearch.widgetset
   ..MyApp.class
   ..MyApp.gwt.xml
---com.example.vaadinresearch.widgetset.client
   VClientComponent.class

正在更新${widgetset}。。。
记住在web.xml中定义widgetset，如下所示。
初始化参数
参数名称WidgetSet/参数名称
参数值${widgetset}/param值
/初始化参数
正在将${widgetset}编译到${client-side destination}目录中。。。

在web.xml文件中，您必须添加

    <init-param>
        <param-name>widgetset</param-name>
        <param-value>you.widgetset.package</param-value>
    </init-param>

widgetset
you.widgetset.package

在应用程序servlet中。您可能还必须具有包含以下内容的widgetset.gwt.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 1.7.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/1.7.0/distro-source/core/src/gwt-module.dtd">
<module>
    <inherits name="com.vaadin.DefaultWidgetSet" />
    <inherits name="you.widgetset.package" />
</module>

谢谢！但问题是在GWT编译之前我没有编译类。因此，除了其他JAR中的类之外，它找不到任何类。我的错（谢谢你把你是怎么解决的，而不是“哦，我已经找到问题了”。讨厌别人那样做。
