The method would return a java.lang.Object since that's what the library's
execute method does. This Object would be what is returned as the <value>
of the response. For example, this response:
<?xml version="1.0"?>
<methodResponse>
<params>
<param>
<value><string>South Dakota</string></value>
</param>
</params>
</methodResponse>
the execute method would return an Object but should be cast into a String.
I don't think Turbine *should* ever see the raw XML since the library would
wrap it all up.
Hopefully this makes some sense. I did some early Java work with XML-RPC
and I think it would be a great addition to Turbine. I'd love to help with
it.
