This is an excerpt from WS-I Basic Profile clarifying the issue: "For document-literal bindings, the Profile requires that at most one part, abstractly defined with the element attribute, be serialized into the soap:Body element."
But the SOAP specification allows for multiple children under the "soap:Body" element (see http://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383503). "The element MAY contain a set of body entries each being an immediate child element of the SOAP Body element. Immediate child elements of the SOAP Body element MAY be namespace-qualified. SOAP defines the SOAP Fault element, which is used to indicate error messages (see section 4.4)." And the "SOAP Version 1.2 Part0: Primer" specification has the very first example showing multiple children under the "soap:Body" element - see http://www.w3.org/TR/2003/REC-soap12-part0-20030624/#Example. Apart from that .NET handles this case very well, so it seems that it can be done. IB -----Original Message----- From: Anne Thomas Manes [mailto:[EMAIL PROTECTED] Sent: February 10, 2005 3:36 PM To: [EMAIL PROTECTED] Subject: Re: Can't invoke method with multiple arguments This is not a bug -- this is a requirement of SOAP. The child element of the SOAP body indicates to the SOAP processor how to handle the request. This child element must provide a unique signature so that the SOAP processor can figure it out. The SOAP specification doesn't specify how to process more than one child element in the SOAP body. The WS-I Basic Profile has clarified this point and specified a rule that says that the SOAP body must contain at most one child element. When using document/literal, you must wrap your parameters with a single element, and this element must be used as the one and only child element of the SOAP body. If you use the wrapped style, Axis will do this for you automatically. - Anne On Tue, 8 Feb 2005 17:17:01 +0100, David Werner <[EMAIL PROTECTED]> wrote: > Hallo Ioan, > > I'm quite stunned by this bug!
