Re: [Asterisk-java-users] Asterisk Live package

Hi Stefan,
  
  I would like to know where can I find the ManagerConnectionPool. I am  looking into the SNAPSHOT 3.0 version javadocs and I don't find any  class. I am also having some thread issues with manager connection.  Here is my problem details.
  
  I am using a agi to authenticate/originate a call and this agi is  called from asterisk extensions. This agi also fires an Timer task, and  this timer task will set the timeout every 3 minutes after checking the  balance of the user who is already in the call. I am following reserve  and capture mechanism to do the calculation. So, if there are 10 calls  initiated by agi, there are 10 timer tasks running in 10 threads. I am  creating one single manager connection and pass them to TimerTask. Each  TimerTask's run() method will do the login everytime we need to send  the Timeout action. My finally class has the logout() method for the  connection. Whenever the channel hangup, i will check the response from  asterisk to determine whether I continue run the timertask or cancel.  This works without any problem for sometime. I noticed atleast after  2-3 hours i m getting lots of errors in the application server logs.  Here are some samples.

  I don;t know why I am getting this ClassCastException error. If I  restart the server its fine. Please help me eliminate this errors.
  
  Thanks and sorry for the long email,

yes the ManagerConnectionPool is there but it is only used with one
connection right now and that works well even with high traffic servers.
The idea behind this is using one connection for receiving events and
multiple connections with eventMask set to off for sending actions.
I am not sure if this design is superior to using only one connections
are there are rumors that Asterisk has synchronisation issues when using
multiple concurrent connections.
So if you did not experience any problems up to now you are probably
fine with just one connection.
