[jboss-user] [Beginners Corner] - Re: How to reliably count active sessions (re-post)

[mrgordonz]

Hi Peter,

The installation of JBoss in this case is bundled with an application (Saba), and the Saba engineers have "tweaked" JBoss such that it listens on port 1098, not 1099.  I have no idea why they did this, but when I check to see which ports are open (ie: being listened on), JBoss is listening on port 1098, not 1099.  

Here is what happens when I try it using the default port:

D:\SabaWeb\JBoss_Tomcat\bin>twiddle -s localhost get "jboss.web:host=localhost,path=/Saba,type=Manager" activeSessions

Perhaps the changed port number is what is causing twiddle to sit there and do nothing - I've tried letting it go for a coupe of hours and it never returns a result.

Cheers,
