Way to learn active sessions in SipServlet.

[alp carsikarsi]

Hi,

I wrote a sip servlet. And i want to learn active sessions (active calls) in my Servlet. I found HashMap solution for it. When call start i put the session in to my HashMap and when it's over i remove them.
But i want to know if there is another way to learn active sessions in my Sipservlet. I asked it because my sip servlet may run in different clusters, and may needed to meet High Availability requirements.

Thanks a lot.

There is a listener (I thoink it is SessionActivationListener) that will help do this.

Hello Michael Ku ,

Thank you for your cooperation.I searched for SessionActivationListener but i couldn't find any results.Did you mean "SipApplicationSessionListener" by saying SessionActivationListener ?
Unfortunately, SipApplicationSessionListener doesn't have any methods for giving active sip sessions or any other sessions.
SipApplicationSessionListener's methods are :
sessionExpired
sessionCreated
sessionDestroyed
sessionReadyToInvalidate

I think Michael meant the HttpSessionListener

SipApplicationSessionListener is not part of the servlet spec.

Can you post the URL for the API you're using?

I am using a Eclipse plug-in Ericsson IMS Application Development Tool (SDS).
It gives support for SIP JSR 116 compliant target servers.
I'm running my sip servlet application in open source GlassFish/SailFin server.

Plug-in's web site :

SIP JSR 116's web site :

Thanks a lot by the way.

How HttpSessionListener be a solution for my problem ? It's got only sessionCreated and sessionDestroyed methods. I think they're for notification for session created and ended.I need a active sip session list.
I want sip active calls in my pocket without using hash map.
