Hello, what you want to do simply you cannot do it in Java because it would be something platform dependant. Maybe you could look for a Single Sign On Module but I'm not aware of any that can do what you want. The only thing you have got from a Java Main is System.getProperty("user.name") which will return your windows user name. regards View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4175340#...
