[tianyun]

例子是在jbuilder 9 中使用struts 来建立一个Webapp.请高手指点.问题解决马上给分.谢谢

[tianyun]

javax.servlet.ServletException: Cannot retrieve mapping for action /

javax.servlet.ServletException: Cannot retrieve mapping for action /

将这里改了.马上又出现以下的错误.

[redex]

建议先手动编译、运行一下试试，先不要用jb，有时jb中
会出现莫名其妙的问题.

[tianyun]

手动编译是什么意思呢?
是自己建一个tomcat + struts 来做吗?

[tianyun]

如何才能解决这个问题,一个例子都那么难做吗?请高手帮忙.分类一定给.

[tianyun]

顶,请大家帮忙.
