I was just fretting over not getting the benefit of hot deploy. Since it not available for jar files on Windows, I'm not leaving anything on the table, so to speak. I've got jboss-4.0.1RC2 and Java version: 1.4.2_07. This isn't critical, but it doesn't seem to delete the tmp files when it restarts. But no matter, really, since I've got to go to the server to restart JBoss anyway, its easy enough to wipe the temp files myself. I put this at the end of shutdown bat (just a random IP - no native 'sleep' on Windows): | rem wait a few seconds | ping -n 1 -w 5000 192.168.234.234 | erase "C:\jboss-4.0.1RC2\server\default\tmp\deploy\*.*" /s /Q | --Dale-- View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008757#...
