Suggest a pattern

[Ramu Nur]

Hi,
I'm working on some exercises on patterns. I've a requirement wherein the request object is same for 8 methods which invoke a webserice but the response object vary. In responses, some are objects, some of boolean, some are void. The legacy webservice is designed in such a way that response depends on request xml name.

What can be a better design pattern to consider. I thought of template method, but the template method response has to be Object and I don't want to cast it back based on request name. I can have 8 methods, but is there any alternative?

Thanks in adv.

What's wrong with each method sending the request, and then just returning a different type?
