WSDL inout parameters

In WSDL specification [2.4.6 Parameter Order within an Operation] has
reference to in/out parameter:

"If a part name appears in both the input and output message, it is an
in/out parameter"

In JAXRPC specification [4.3.4 WSDL Operation] it says that out and
inout parameters are passed by value (copy).

My questions/doubts are:

-How is that inout parameter is passed in WSDL and how is it mapped in
the SOAP message?
-How is that the Java interfaces handle that parameters?
