No I mean use explicit datatypes and not xsd:any which is a sort of
wildcard.
Yeah that's my question. But is there a defined datatype in XML Schema for
an Object ? Or should i define a new datatype somehow?

Oh ok, thanks for the link.

I'm not sure what the issue is. Do you mean what specific methods to call
for
a particular WSDL->Java generated package? I always just look at the
generated
stub code directly (typically via IDE inspection mechanisms).
I mean, in the book, there are only simple examples. Remote methods only
take basic datatypes as arguments (int, string, float, no argument.. or
sequence of those) and return values (int, string, float, void..).
In my code, i want to get an instance of a class as argument, and return an
instance of another class. So i wonder how to specify this in WSDL. That's
the issue :)
