我从 jboss.org/gatein 网站得到了这个例子，我只是把它打包
mvn package
所有 Maven 阶段都是成功的。我将 jsf2-hello-world-portlet.war 复制到
gatein\server\default\deploy
在 server.log 中，我看到以下输出：

请注意，来自同一个 GateIn 快速入门的“simplest-hello-world-portlet”部署成功（我可以使用它添加到页面），并且我自己的示例 portlet 部署成功，但是当我将它添加到新门户页面时，它写给我“Portlet 错误”而不是 Portlet 的内容。
我正在使用 JBoss GateIn 3.2.0。
