Agree with Bill but....
Exchanging String objects, you're gonna use RPC/Encoded. This communication model is strongly discouraged by WS-I.
So if you want to be WS-I compliant, I guess you'll have to use a LITERAL Encoding.
According to Sun, if you want to
exchange XML, you must use a javax.xml.transform.Source Object.
But String is simpler, and it does work.
