Hi Darek,

This is a problem with your web server, not Axis.
You will need to check the server documentation on how to make more =
threads available to the listener. For example, on Weblogic you can set =
up a separate queue, and I know there is something similar (not sure of =
the details) on JBoss.

Hope this helps
Keith

Hi,
I deployed simple web serice (Calculator) using wsdd.

<deployment xmlns=3D"http://xml.apache.org/axis/wsdd/"
            =
xmlns:java=3D"http://xml.apache.org/axis/wsdd/providers/java">
 <service name=3D"C" provider=3D"java:RPC">
      <parameter name=3D"className" value=3D"com.my.Calculator"/>
      <parameter name=3D"allowedMethods" value=3D"*"/>
      <parameter name=3D"scope" value=3D"session"/>
 </service>
</deployment>


Then i have a client in java which is trying to invoke add method of =
this
service 30 times like that:
(..i am trying to pretend 30 users clicking add button ..)


 ...
 for ( int i =3D 0 ; i < 30 ; i++)
  {
   Zad z =3D new Zad(i1.intValue(), i2.intValue());
   z.start();
  }
  ...
class Zad extends Thread
{
 int a, b;
 public Zad(int a, int b)   { this.a =3D a; this.b =3D b; }

 public void run()
 {  try
      {
            String endpoint =3D "http://localhost:8080/axis/services/C";
            Integer i1 =3D new Integer(a);
            Integer i2 =3D new Integer(b);

        Service  service =3D new Service();
        Call     call    =3D (Call) service.createCall();

        call.setTargetEndpointAddress( new java.net.URL(endpoint) );
        call.setOperationName( "add" );
        call.addParameter( "op1", XMLType.XSD_INT, ParameterMode.IN );
        call.addParameter( "op2", XMLType.XSD_INT, ParameterMode.IN );
        call.setReturnType( XMLType.XSD_INT );

          Integer ret =3D (Integer)call.invoke( new Object [] { i1, i2 =
});
           System.out.println("Got result : " + ret);
  }catch(Exception e)   {   e.printStackTrace();   }
 }
}

but i've got an Exception after some well done  adds

Got result: 2
Got result: 2
...
Got result: 2
Got result: 2
AxisFault
....
stackTrace: java.net.ConnectionException: Connection refuse: connect
.....


If anyone know, am i able to invoke 100 add methods (of my calculator
service) at one time?
soppose it is a public service and 100 users at one time would like to =
add
some integers.
