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

Question

我创建了一个 PHP Liferay Portlet，并在 portlet.xml 中添加了此类:

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

当我部署 portlet 时，出现此错误:

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

这意味着找不到从 ServletContextPath.java 导入的类 com.caucho.vfs.Path ( Source )。

如何解决这个问题？我需要导入该类吗？
