使用Tiles的Struts 2应用程序中的错误:java.lang.NoClassDefFoundError:org/apache/tiles/listener/TilesListener [英] Error in Struts 2 app with Tiles: java.lang.NoClassDefFoundError: org/apache/tiles/listener/TilesListener

问题描述

尽管我已经为Tiles放置了必要的jar文件，但我遇到了此错误:

I am getting this error, although I've already put necessary jar files for Tiles:

SEVERE: Exception while loading the app 
SEVERE: Undeployment failed for context /FinalTilesStruts2 
SEVERE: Exception while loading the app : 
 java.lang.IllegalStateException: ContainerBase.addChild: start: 
 org.apache.catalina.LifecycleException:
 java.lang.IllegalArgumentException: 
 java.lang.NoClassDefFoundError: org/apache/tiles/listener/TilesListener

推荐答案

仅在Tiles 2.0.3中可用的类 org.apache.tiles.listener.TilesListener ，您可以下载此处.

The class org.apache.tiles.listener.TilesListener only available in the Tiles 2.0.3 that you can download here.

在更高版本的Tiles中，侦听器类为 org.apache.tiles.web.startup.TilesListener .

In higher versions of Tiles the listener class is org.apache.tiles.web.startup.TilesListener.

如果可以帮助您解决正确的侦听器类的问题，则可以阅读此答案.

You can read this answer if it help you resolve problem with the right listener class.

如果将Tiles 2与Struts 2一起使用，则应使用

If you are using Tiles 2 with Struts 2 then you should use

<listener>
    <listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
