Connections release

[Etienne Vincelette <et...@pco-innovation.com>]

Hi,

I have some difficulty to release connection to a OpenEJB server. My client
application have a a manager that create the initial Context and retrieve a
Stateless bean. Before each call the the bean, the manager call a ping
method on this bean. If the ping doesn't respond we retrieve a new bean from
the pool. The bean is share between many thread. In heavy load tests, we
didn't had any problem for sharing the bean between threads. On production
server, we got error when the MaxSize connection is reached, event with
StrictPooling set to false. So we try to set MaxAge or IdleTimeout property
but connection aren't released. So we set the MaxSize to 0 to avoid blocking
situation.

There are my questions : Should I use one thread by bean? Is there a reason
why creating bean fail with StrinctSpooling set to false and MaxSize
reached?

Here is me connection verification method (client side):

private MyService cs;
synchronized private void connect()throws NamingException{
  try{
    cs.ping();
  }
  catch(Exception e){
    cs = null;
  }
  if(cs == null){
    setContext();  //create context if not accessible
    Object ref = context.lookup("MyServer/MyService");
    cs = (CryptoService)ref;
  }
}

Here is my OpenEJB configuration file:

<?xml version="1.0" encoding="UTF-8"?>
<openejb>
<Container id="My Singleton Container" type="SINGLETON">
  AccessTimeout = 30 seconds
</Container>


<Container id="My Stateful Container" type="STATEFUL">
  AccessTimeout = 30 seconds
  Passivator   org.apache.openejb.core.stateful.SimplePassivater
  TimeOut  20
  Frequency 60
  Capacity  1000
  BulkPassivate  100
</Container>


<Container id="My Stateless Container" type="STATELESS">
  AccessTimeout = 30 seconds
  MaxSize = 0
  MinSize = 0
  StrictPooling = false
  MaxAge = 0 hours
  IdleTimeout = 0 minutes
</Container>
