Another (lame) alternative is adding your stuff to a path that has no spaces in it. You also need to add a space char before the -D, as I did above, otherwise it won't work. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/546358#546358] Start a new discussion in JBoss AOP at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
