Re: [Freeswitch-users] mod_java - usage question
To accomplish what you are wanting with mod_java you would need a way to invoke another thread outside of the call to assume control of the channels rather than trying to do it from the call's thread. In javascript there is a jsrun api command that will launch another script in it's own thread with no calls in it. I assume the author of mod_java could extend it to do something similar so you could run a management app that listens for events and acts accordingly. Also you could use the event_socket with a standalone java app to manage the calls from a separate entity. But by design the high level interfaces block on things like playback and bridging but allow callbacks to be connected for things like read frame and dtmf and message reception. You can always do it in C where you have full control and ability to launch threads etc. Anthony Minessale II FreeSWITCH http://www.freeswitch.org/ ClueCon http://www.cluecon.com/ AIM: anthm MSN:anthony_minessale@hotmail.com GTALK/JABBER/PAYPAL:anthony.minessale@gmail.com IRC: irc.freenode.net #freeswitch FreeSWITCH Developer Conference sip:888@conference.freeswitch.org iax:guest@conference.freeswitch.org/888 googletalk:conf+888@conference.freeswitch.org pstn:213-799-1400 ----- Original Message ---- From: jonathan augenstine <jaugenstine@gmail.com> To: freeswitch-users@lists.freeswitch.org Sent: Tuesday, December 11, 2007 12:58:55 AM Subject: Re: [Freeswitch-users] mod_java - usage question Damjan, What I want to do is the following: incoming call - play a prompt - bridge incoming to endpoint 1 - endpoint 1 hangs up - park the incoming call originate call to endpoint 2 - play a prompt to endpoint 2 - bridge endpoint 2 to endpoint 3 - endpoint 3 hangs up - bridge incoming call to endpoint 2 The details on how to accomplish this with mod_java are eluding me.

How do calls "block"? Use a remote debugger and see where it
happens.
If I run the following code:
session = new JavaSession(sessionUuid); freeswitch.console_log("notice", "STARTED!!!\n");
session.streamFile ("/usr/local/freeswitch/sounds/intro.wav", 0); session.execute("bridge", "sofia/gateway/[gatewayname]/3237773456");
freeswitch.console_log("notice", "COMPLETED!!!\n");
I do not see the "COMPLETED!!!" console message until one of the callers from the "bridge" hangs up. The
session.execute("bridge",.....) call blocks.
session.execute() is supposed to block until the application finishes running. I'm not sure why that's a problem, you only want to park the call after bridge is finished.

When there is no other function that does the job, try the execute()
method in mod_java. Event sockets can probably do the same, but I've found them harder to work with (don't know if there are any APIs that make it easier), and since they cost 2 sockets and probably 1
thread per call and if on the same machine double the number of context switches, they are more resource intensive too.
As illustrated above I am using the execute.

Anthony, Thank you for the clarification. I am beginning to understand basic behavior and design. I am constrained by the fact that the customer wanted a Java solution. I have concluded (based on discussions with Brian West) that a good solution would be to wrap the event socket interface in Java. The customer requested that I prototype the app with mod_java first. I have concluded that the final app will probably be multiple apps using both event sockets and mod_java. Also, I was to resolve some issues during the process of trying to explain my dilemas to Damjan. I have a call flow, I just need to work out the method details. Damjan, I realized the solution to my problem was to park the first incoming call. The one last detail I have not worked out is how to bridge the second call to the parked call. I think this is the solution. Will execute("park", "") block or not?? Any hints would be nice. Thanks for all the help. Jonathan On Dec 11, 2007 6:27 AM, Anthony Minessale <anthmct@yahoo.com> wrote:

Damjan,
What I want to do is the following:
incoming call - play a prompt - bridge incoming to endpoint 1 - endpoint 1 hangs up - park the incoming call
originate call to endpoint 2 - play a prompt to endpoint 2 - bridge endpoint 2 to endpoint 3 - endpoint 3 hangs up - bridge incoming call to endpoint 2
The details on how to accomplish this with mod_java are eluding me. Every approach I have attempted I have encountered roadblocks of either hitting execute blocking what I need to do or not having the right info (what needs to be passed to originate or how to play a prompt to endpoint2 or bridge to endpoint 3).
