J2EE 部署项目报错

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

解决：1、把下面的内容配置到web.xml中

（我第一次用的这个，暂时对了。）

<!-- 用来定位Spring XML文件的上下文配置 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>

</context-param>

附：这个做法虽然能使服务器启动起来，但是当后面提交表单时就会出Unable to instantiate Action的错，因为这样写根本就让服务器找不到正确的applicationContext.xml文件。所以这样写是错的。

我的错误和楼主一样，但是被sz274071580这种做法迷惑了，一直找Unable to instantiate Action的错，浪费了很长时间

原来我根本的错误就是少了一个commons-pool.jar

2、据说加一个commons-pool.jar包就可以了。。

3、其实，1和2都做了以后，部署没有报错了，但是运行的时候，会有空指针。然后我改了一下1的东西，改成了

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext.xml</param-value>

</context-param>

终于运行成功了。

ps：1的方法有的人说找不到正确的app....xml，其实是因为它本身路径的问题。
