filter在web.xml没配正确

[哆来咪法索拉西]

这个你参考下

我有struts2的样例
我到查了一下说
Exception starting filter struts2
这个错误是因为tomcat安装目录有空格
改成
<constant name="struts.devMode" value="true"/> 或者把下面这个true改成false
<constant name="struts.configuration.xml.reload" value="true"/>
或者重新安装tomcat同时目录不要有空格就行
我按第一种改了问题还在 而且我自己写的struts2就能运行
不知道要是重新安装tomcat行不行？

应该是web.xml配置文件出问题了
