我的com.mot.rbt.listener.RBTSessionListener存在，class也存在，怎么会出现这个问题
路径都对，包也没有问题。这个工程在其他机器上没问题，在另一台新机器上部署就出了这个问题，里面的东西代码都没有改过。
请教大家，怎么解决
eclipse 报错如下
SEVERE: Skipped installing application listeners due to previous error(s)
Sep 9, 2010 9:51:41 AM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Sep 9, 2010 9:51:41 AM org.apache.catalina.core.StandardContext start
SEVERE: Context startup failed due to previous errors
web.xml部分内容如下
<web-app>

<description>Resource Booking Tool</description>
<listener>
<listener-class>com.mot.rbt.listener.RBTSessionListener</listener-class>

Answer 1

删掉没有用的jar文件，这时候可能还会报错，但是错误已经很转移成其他的，根据报错的提示不断完善就可以了，本人已完成过，望采纳！

Answer 2

如果排除程序配置的问题,就只能是tomcat启动时的毛病了。
个人怀疑tomcat启动时分配的内存不够，导致部分jar没有被读取。

删除$CATALINA/work中的内容，启动文本中添加-Xmx，数值弄大一点，例如-Xmx1024试一下效果如何

Answer 3

项目没有引tomcat的servlet-api.jar包，引一下包就好了

Answer 4

web.xml里面的class和listener顺序的问题吧，你最好把配置文件粘出来大家看看
