How to use SoapUI through command line

Hi,

We have a requirement to provide a tool which can make SOAP call with required input parameters in Soap request and generate response.

We will select SOAP service and pass required WSDL file with input parameters to generate soap request through UI and then back end should use those input values and using Soap UI generated soap request and response.

Can you please help me or give me some pointer to start?

thanks,
Nili
