Choose your preferred JRE and select edit 4. select the option Add External Jars and add to it tools.jar from your JDK's lib folder recycle your sever and you would see in the logs at bootup the classpath contains tools.jar View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4220731#...
