我从 jboss.org/gatein 网站获得了这个示例，我只是用
打包了它mvn package
所有 Maven 阶段均成功。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，同一 GateIn Quickstarts 中的“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，但是当我将其添加到新门户时页面，它给我写的是“Portlet 错误”而不是 Portlet 的内容。
我正在使用 JBoss GateIn 3.2.0。
最佳答案
JSF 库丢失。它们必须添加到服务器的库或 web 应用程序的库中(只需删除 pom.xml 中的“provided”范围)。
请注意，快速入门仅使用 Gatein 3.6 和 JBoss AS 7 进行了测试，如所述 here 。使用此配置，它可以正常工作，开箱即用。
