Trouble porting an RI implementation into portal

[mwelch16]

Hello,
I'm using the 2.2.1sp2 bundled version of jboss portal (downloaded). I'm using the built in hibernate virtual database and running JBoss on my PC (Windows XP). I am trying to integrate a JSF RI implementation into the portal. The JSF application currently runs in the 4.0.2 AS version of JBOSS. While integrating I am experiencing what appears to be conflicts between the RI and my faces. I don't know if it's a classpath issue, my war file, or an actual conflict. The portal seems to be trying to cast to a JBossRenderResponse and the RI code is using an HTTPServletResponse. Any advice would be helpful. I was hoping the RI application would work with very little change.
Thanks,
Mark
