Ah, awesome. Thank you for clearing that one up and your package is =
defined in the struts.xml in the root of the source?

James,

What I normally do is create a "package" and set the defaults that I
want stuff to use (interceptors / interceptor stack / etc.). Then, I
just tell the convention plugin to use the package I configured....

The list of properties that the plugin uses is here -
http://struts.apache.org/2.x/docs/convention-plugin.html#ConventionPlugin=
-Configurationreference

I think the setting is -

struts.convention.default.parent.package=09
