Hi,
We are currently trying to update from webwork to struts 2.0.6,
everything looks fine except one thing.
The application is deployed into JBoss 4.0.4 and JAAS is enabled into
our web.xml configuration file. So when trying to access the secure
namespace, it does its check and finds out that the user is not logged
yet so its redirecting to our configured JSP, into this JSP, we have
struts tags and we are applying a decorator.
With Webwork, it was working perfectly, but now, in Struts 2.0.6 we have
the following stack.
Anyone knows what we are doing wrong ?
java.lang.NullPointerException
