Struts2 - JSF Plugin in portal environment

[Michael Bowman <bo...@gmail.com>]

Hello,

I'm trying to get Struts2 working in a portlet environment... so far,
so good. However, we have one portlet that requires the use of some
3rd party jsf components. So I've been trying to get the jsf plugin to
work with the struts-portlet-default stuff. First thing I noticed, was
that the jsf-default definitions in the struts2-jsf-plugin-2.0.6.jar
extend struts-default. Since I needed one that extends
struts-portlet-default, I copied the package definition over to my own
struts-jsf.xml file and made the appropriate changes...

If anybody could help me out with this and let me know where I've gone
wrong, it would be greatly appreciated.

Thanks!
