我们使用 seam+richfaces+gwt，效果很好。尽管我们使用 maven 构建一切，但我想您也可以使用 ant。总体思路是在 GWT 开发模式下启动整个 Web 应用程序。您不必编译所有内容（在 GWT 编译器的情况下需要很长时间）。开发模式将按需编译请求的资源。通过以这种方式运行 GWT 应用程序，您还可以调试客户端代码。
也可以调用 GWT 方法来响应接缝动作。

我可以详细说明一下我们的解决方案：
马文
您的项目应配置为packaging: war. 有一些关于使用 maven 设置接缝的官方说明（也是richfaces）：
http://docs.jboss.org/seam/2.2.1.CR2/reference/en-US/html/dependencies.html#d0e34791
http://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/SettingsForDifferentEnvironments.html
对于 GWT，将以下部分添加到您的pom.xml：
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.1.0</version>
<scope>provided</scope> <!-- prevents from including this in war -->
</dependency>

<groupId>com.google.gwt</groupId>
<artifactId>gwt-dev</artifactId>
<version>2.1.0</version>
<scope>provided</scope> <!-- prevents from including this in war -->
</dependency>
<dependency>
<groupId>pl.ncdc.gwt</groupId>
<artifactId>gwt-servlet-war</artifactId>
<version>2.1.0</version>
<type>war</type> <!-- adds gwt-servlet.jar to your war, but not to your classpath -->
</dependency>

此配置应该与 - seam 和 gwt 编译产生战争。如果您想在开发模式下使用此类项目，请将其放入pom.xml：
<dependency>
<groupId>com.xemantic.tadedon</groupId>
<artifactId>tadedon-gwt-dev</artifactId>
<version>1.0-SNAPSHOT</version>
<scope>provided</scope>
</dependency>
并添加-server com.xemantic.tadedon.gwt.dev.JettyLauncher到您的谷歌网络应用程序启动器。这是 maven 友好的码头发射器，在某些情况下可能是必要的。
我希望它会帮助你。您对 gwt 和richfacaes 应用程序之间的通信感兴趣吗？
