It SOUNDS like you might be picking up a couple versions of jaxb-xjc, but I'm not really sure. I'm not really familliar with the ant classloaders so I'm not sure what to suggest.
You don't need any of the xjc jars at runtime, just build time. Thus, I wouldn't put them in webinf/lib or anything like that. I would keep them separate and just add the required xjc plugin jars as needed to the classpath of whatever you are using to call xjc.
