Subject Re: There is no Action mapped for namespace / and action name ...
Date Fri, 29 Aug 2008 15:11:26 GMT

having the same problem:
i use Struts2.0.11.2. and tomcat 6.0.16.
On my Windows desktop everything works fine. I exported the project as war
and imported it on my Linux laptop (so i can work a little bit in my
hollidays). 
But on the Linux laptop i only get a
"There is no Action mapped for action name index.".
My xml-files are UTF-8 coded on both machines so i have no idea where the
problem is rooted in.
I'm using JRE1.6.0_07 on both machines, setting the compliance level to 1.5
didn't change anything. The tomcat startup shows no problems either.

What libraries did you change?
