所以这一切都始于尝试让 Coldfusion9 portlet 在 Liferay 下运行，就像我看到的运行 JBOSS 的示例一样：http: //help.adobe.com/en_US/ColdFusion/9.0/Developing/WSC00E3E9C-DC24-4488- 930D-AEED19172CC5.html
我遵循了这些步骤，但我的应用程序服务器将是 TomCat 5.5（与 Liferay 5.2.3 捆绑）。
我想从coldfusion 创建一个portlet（只是一个hello world 开始）。
安装进行cfusion得很顺利，我创建了WAR文件，并将其放入 Liferay 'hot depoly' 目录中，它被复制并无错误地集成到 Liferay 安装中。
我按照 JBOSS 示例中的步骤重新启动 Liferay 服务器（将.cfc文件复制到正确的位置后）。
然而，在我启动 Liferay 之后，我在启动过程中遇到了这个错误：

现在，为了嘘声和笑声，我尝试在 Liferay 上设置一个 portlet（portlet 出现了！耶！）。然而，只有 portlet 的标题会显示出来，正文是一条错误消息：
The requested resource (/cfusion/ColdFusionPortlet/invoke) is not available
现在我似乎无法找到解决方案......我用谷歌搜索，并查看了很多文件，没有人提到这种类型的错误。当然 Liferay.com 社区很安静，那里的论坛上没有冷融合讨论。所以我想我会和 SO 的每个人核实一下。
任何人？想法？
