[Zope] SOAP Method

Hi All, I'm trying to use the SOAPMethod product to use some web service from ZOPE. I was able to call a web service that doesn't take any parameters (RPC Style). I created a SOAP Method called "ws1" which calles a simple web service and called it int eh following manner from the browser. http://localhost:8080/ws1 And it gave me the proper response. But when I'm using the a SOAP MEthod how can I pass parameters into a webservice from the browser. I tried to use the following but it didn't work :-? http://localhost:8080/ws1?param1=value1 Any idea will be really helpful :) Thanks Ruchtih
