newbie question: CommonsHTTPSender examples

[Ada Lam]

Hi all,
Can someone send me examples of how to use 
org.apache.axis.transport.http.CommonsHTTPSender class to send SOAP message?
The only example that I can find is to specify it in wsdd.  

Currently, I send SOAP message like this:
  Service service = new Service();
  Call call = (Call) service.createCall();
  SOAPEnvelope elemenv = call.invoke(env);
(env is a SOAPEnvelope.)
I want to use CommonsHTTPSender so that I can use POST HTTP/1.1.
Thanks in advance!
Regards,
 Ada
