Dear newsgroup, I installed Jboss jboss-4.2.2.GA under windows XP SP2. When I type this address: http://localhost:8080/ Jboss displays the corresponding welcome page :-) if I type http://127.0.0.1:8080/ It works well! That is to say the IP address "localhost" or 127.0.0.1 work fine. But if I replace the URL address by the DHCP IP address allocated by the server to my computer, then it doesn't work anymore. By that, I mean that nothing is displayed by Jboss when I type the address, execept "The page cannot be displayed". e.g. http://157.125.0.1:8080/ Do you have an idea of what can be wrong? Thank you for your feedback and comments. Jose View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4148327#...
