Call.setProperty and Call.setSOAPVersion

[Ravi Krishnamurthy]

Hello:
I'm trying to write a dynamic invocation client. Lookes into some of the 
stubs generated by WSDL2Java and saw the following lines:

       _call.setProperty(org.apache.axis.client.Call.SEND_TYPE_ATTR, 
Boolean.FALSE);
       _call.setProperty(org.apache.axis.AxisEngine.PROP_DOMULTIREFS, 
Boolean.FALSE);
       
_call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS);

Could somebody give some pinters on how to get this information so that 
I can do in my dynamic client if it is necessary.

Thanks,
Ravi
