[jboss-user] [Beginners Corner] - javax.crypto.Mac

If I try to get an instance of a javax.crypto.Mac, usingjavax.crypto.Mac mac = javax.crypto.Mac.getInstance("HmacSHA1");, I get a NoClassDefFoundError. I've looked at the JRE (Sun 1.5.0.10), and see jce.jar in the lib directory and sure enough javax.crypto.Mac.class is in that jar, so I wonder why it isn't loading in JBoss and how to make it do so.
