Kobe Nys commented on WW-2967:
------------------------------

I downloaded the version 2.1.7 from location: 
  http://people.apache.org/maven-snapshot-repository/org/apache/struts/struts2-showcase/2.1.7-SNAPSHOT/ 
But this version doesn't resolve this problem... Is that normal should I build a version from subversion in order to have a working jar or ...

Thx,
Kobe.

> I created a little sample project to show the "power of struts2" and all works perfect. When I incorporate it inside the existing application it doesn't work anymore. Maybe conflicting jars I don't know. I get the following error:
