java.lang.ClassNotFoundException: com.caucho.vfs.Path

Question

我已经创建了一个Portlet，并在portlet.xml中添加了这个类：

<portlet-class>com.liferay.util.bridges.php.PHPPortlet</portlet-class>

当我部署portlet时，会得到以下错误：

这意味着找不到从ServletContextPath.java (来源)导入的类来源。

我该如何解决这个问题？我需要导入那个类吗？

将resin-util.jar添加到类路径中。你可以从这里下载它
