我有vadin 6.8.6应用程序，并使用ant来构建它。现在我想重新编译我的应用程序使用蚂蚁，但编译器没有看到我的小部件，我在我的应用程序中实现。所以我有这样的蚂蚁构建脚本。在我的项目中，我有packages
com.example.vaadinresearch
..ServerComponent...class
--com.example.vaadinresearch.widgetset
..MyApp.class
..MyApp.gwt.xml
---com.example.vaadinresearch.widgetset.client

在web.xml文件中你必须添加
<init-param>
<param-name>widgetset</param-name>
<param-value>you.widgetset.package</param-value>
</init-param>
在VaadinApplication servlet。您可能还需要有一个widgetset.gwt.xml文件，其中包含以下内容:
<?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>
