<constant name="struts.devMode" value="true"/> 或者
<constant name="struts.configuration.xml.reload" value="true"/>

devMode模式是开发模式,开启它则默认开启了i18n.reload、configuration.xml.reload。这个错误是由于configuration.xml.reload设置为true导致的, 原因很简单,tomcat的安装路径包含空格
把tomcat安装目录里的 空格删了就行了......试试吧...很简单的..
.再 把 myEclipse的工作区间 的 空格 去了....都不要 空格
把那两个冲突的东西都注释掉
