We have installed version 7.1.3 on our server but when some error comes like 404 ( on page not found) then why we received below thing in the error message?
It creates confusion in the mind that are we using the right version or not?
The version you are seeing in the exception report is the version of the web server being used in JBoss AS7. There are ways to hide it, from what I remember. Take a look at some of the threads in the JBossWeb forum here.
