Ahh! Found the solution indirectly on another post. Here it is for future readers with the same problem: You need to add a tag in your application.xml referencing the jar. This jar needs to be in your ear directory not WAR/lib. I'm still baffled why this jar needs the special treatment and certain other jars can just be dropped into WAR/lib without issue. Not one to question the wisdom of sages or what works--I just did it, but I am curious what constitutes the difference between some jars and others.
