Hi jatsrt: When creating a new server, you should type directly into the combo box the ip address you want. The combo box is supplied by webtools and is not filled with acceptable hosts, however, you can type directly one of the following: localhost 127.0.0.1 192.168.etc.etc So long as what you type in IS a local host, you should be able to create a jboss 4.0 server instance. Hope this helps. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957408#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
