I am using jboss 3.0.6 with jetty as a web server and am having problems with a specific virtual host domain. There are 2 issues really
1) If the .war file begins with a number eg 999xxx.war it will not deploy - strange, but easy to solve by renaming the file.
2) If the virtual host in jboss-web.xml begins with a number eg: www.999abc.com, the web app will not deploy to the virtual host. If the virtual host is changed to something else : ie www.abc.com it works.
