Hi,
I am trying to call 1 method on a SLSB remotely.
I am running the method call in a thread which are being created
In a loop.
BASIC idea is to simulate 50 Users concurrently accessing
If I create 40 threads then everything goes fine. But, the moment
I cross 45, I start getting this error:
java.rmi.ConnectException: Connection refused to host: 192.168.146.134;
nested exception is:
java.net.ConnectException: Connection refused: connect

Code Implementation
================================
private void threadedTesting() throws Exception
{
Context jndiContext=getInitialContext();
Object obj = jndiContext.lookup(JndiNames.QUERY_ENGINE);
qeHome =
(QueryEngineHome)javax.rmi.PortableRemoteObject.narrow( obj,
QueryEngineHome.class );
QueryEngine qe = (QueryEngine)qeHome.create();
for (int i=0; i <retry; i++)
{
Tester t = new Tester(qe,i);
t.start();
}
}
class Tester extends Thread
{
QueryEngine qe = null;
int i;
public Tester(QueryEngine qe, int i)
{
this.qe = qe;
this.i = i;
}
public void run()
{
try
{
System.out.println("Running Tester " + (i+1));
Collection c = qe.getInboxDetails(new
UserPK(12), 1,"1");
System.out.println("Collection Size is =" +
c.size());
}
catch(Exception e)
{
System.err.println("Error in iter " +
i);
e.printStackTrace();
}
}
}
If I call home.create() in run then I get this error at retry = 15-20.
