Threaded Call object

[co...@kent.pnn.police.uk]

Hi,
I have failed miserably to sort this out so I resort the the greater good   
    

      


;-)

I am trying to write a SOAP client that makes threaded RPC calls. The
works when I only inititate one thread but when I do two, the results of   
    

      


the Call.response always appear to be the same for each thread as if the   
    

      


Call object is global in scope and is being set to the last (or first)
thread Call.Response. If I run these as two separate clients (from
different DOS windows), they return different results - but still the
same for each internal Thread, so I don't think it is a server threading   
    

      


problem i.e. my rpc method that is being called isn't the problem but I   
    

      


am willing to be persuaded otherwise!

Can anyone help?????
Thanks
