webservice call without a wsdl
I need to contact with the SAP XI web service. I only know what to send as soap body as string but I do not have any wsdl definition. How could I call this sap xi web sevice without a wsdl? Is it mandatory to have the wsdl for sap xi web service invokation ?
Similarly, from SAP XI, i need to call a web service hosted on the target system, without having a wsdl suppied by the target system. In that case, what is the minimum information i need from the target system to invoke a web service ?
Also, is the solution which you peope give me warrants specific PI version (PI 7.0 or PI 7.1 etc.,) and service pack ?
I appreciate your reply.
