资源文件配置问题,最后这么点分了
小弟初涉jsp的内容,下面这个问题请大家给点意见
我使用的是 tomcat5.5+eclipse3.2开发
项目是在windows下面做的,并且完全正常,然后移植到linux下面就出问题了

大家看看有什么问题,我是把整个工程都直接copy过去的
/src/resources/MyResource.properties
/classes/resources/MyResource.properties
都是存在的,开始以为是大小写的问题,修改之后还是不行,请高手指点一下
[解决办法]
我觉得应该是使用struts标签库中标签出的问题,但是到底是哪个看不出来.你可以把页面上的那些标签都去掉,把标签引入那两行也去掉.然后看看好使不?好使的话就是那些标签的问题了.
