　　d)、修改web.xml文件

               在jbpm-console\WEB-INF下打开web.xml文件，在servlet前加入以下listener，注意：把listener放在所有的servlet前面，我发现网上很多帖子里都没有提到这一点，不知道他们的程序是怎么跑起来的？残念ING～～～

<listener>

     <listener-class>com.sun.faces.config.ConfigureListener</listener-class>

</listener>

<listener>

     <listener-class>com.sun.faces.application.WebappLifecycleListener</listener-class>

</listener>

             这两个监听器很关键，大象先一直没有成功的原因就是没有加这个，而这两个监听器都在jsf-impl.jar包中，jbpm-console这个应用可是用jsf来实现的，如果你不加，则会产生如下这些错误：
