Have you used top to determine what is using up the processor (I assume java, but you never know). What have you deployed to JBoss? Have you looked at the JBoss logs to see what is in there? Have you taken thread dumps to see what code is taking up all the processor time? Oh, and what JVM are you using? To find out, run: "java -version".
