在Tomcat 7上运行PHP

Question

我正在尝试使用these notes在Apache Tomcat 7上设置PHP。我从Web上的研究中对Web服务器的Web.XML进行了更改，它看起来如下：

<listener><listener-class>php.java.servlet.ContextLoaderListener</listener-class></listener>
<servlet>
<servlet-name>PhpJavaServlet</servlet-name>
<servlet-class>php.java.servlet.PhpJavaServlet</servlet-class>
</servlet>
<servlet>
<servlet-name>PhpCGIServlet</servlet-name>
<servlet-class>php.java.servlet.fastcgi.FastCGIServlet</servlet-class>
    <init-param><param-name>prefer_system_php_exec</param-name><param-value>On</param-value></init-param>
    <init-param><param-name>php_include_java</param-name><param-value>On</param-value></init-param>
</servlet>
<servlet-mapping><servlet-name>PhpJavaServlet</servlet-name><url-pattern>*.phpjavabridge</url-pattern> </servlet-mapping>
<servlet-mapping><servlet-name>PhpCGIServlet</servlet-name><url-pattern>*.php</url-pattern></servlet-mapping>

现在，Listener条目似乎阻止了Tomcat7的启动。以下是跟踪数据。有没有人见过或修过这个？请分享您的想法。
