Thanks jaikiran. But now, you make me a little scared. When I insert the "-b 0.0.0.0" in the start of JBossAS 4.2.2.GA a was can access the jmx-console like you said. Then I did another test. I put a application ".war" which was running in the 4.0.2 version in the new version and when I did start the "THE APPLICATION DON'T WORKS". Then I put the "-b ..." and so the application works. My Company is publishing the server in the internet and we do not knows!!! Do You know some literature where I can get the knowledge to fix this problem?
