Problem Deploying To OC4J 10.1.3.1 (Orion) Server

I get this exception when I try to deploy Hudson (1.74) to Oracle's OC4J
container (10.1.3.1). I deploys just fine to Tomcat (5.5.20). Any insight
on what's going on and how to fix? 

I peeked at TagScript.run() and see where it's failing; it is just not
obvious to me as to why. It seems like a namespace issue? Actually dunno...
Any help would be appreciated... Our company uses Oracle's IAS, so seems
a pity to keep around a Tomcat instance just for Hudson, but I'm not suggesting
I won't if have to. Thank you.
