Missing template.... wsdl.rhtml

Hi,

I am using SOAP4R to provide web services. When I dont mention
“expects” and “returns” parameter the wsdl file gets generated but as
soon as I specify the “expects” and “returns” parameter I get a template
missing error which looks something like this,

Missing template … wsdl.rhtml

Can anyone please explain me why is it searching for wsdl.rhtml and what
is the solution to this problem. Any information will be of great help.

Regards,
