And some time I might fix a bug in AXIS myself.

Thank you for the info.

The WSDL I attached was generated by Axis. It seems to me (and I could be wrong) that one should not have to mess with WSDL files. WSDL is basically meant to be4 generated by programs and consumed by programs. For Web Services to really gain broad adoption, the "tools" (Java2WSDL and WSDL2Java) should do the right thing and generate proper WSDL files, so that developers wanting to use Web sesrvices need only concern themselves with the actual implemntation of the service. Isn't that the real concept that Web Services is trying to present?

According to the SOAP spec, Section 4.3:
   1. A body entry is identified by its fully qualified
       element name, which consists of the namespace
       URI and the local name.

Regardless of whether or not you are using doc/literal or rpc/encoded, the
QName of the env:body entry should be unique, and therefore Axis should be
able to determine what to do based on this QName -- even if it isn't a
method name.

In RPC and WRAPPED styles, this QName is the operation name. In DOCUMENT and
MESSSAGE styles, this QName is the name of the element specified in the
input message <part> definition.

Your WSDL messages don't distinguish between the two operations (both send a
message with a QName of {urn:avaya.test.Doit}in0.) I recommend that you
redesign your WSDL so that your input element names are distinct (e.g.,
"add" and "subtract" rather than "in0").

Note that you shouldn't specify a namespace attribute on the <wsdlsoap:body>
definitions when using doc/literal. Axis will, by default, use the
targetNamespace defined in the <schema> definition (which is where you
define your input element). The <wsdlsoap:body> namespace attribute
overrides the default.

I'm also assuming that getString returns a normal string, so I've changed
the type to "xsd:string".

Here are my suggested changes:

The issue here is that DOC/Lit does not carry method
name in the SOAP body whereas SOAP/RPC does. As a
result AXIS doesn't know how to dispatch the method
and my guess is that it will work correctly as long as
you don't have two methods that take the same
parameters. You could get AXIS to use SOAPAction for
doing the dispatch but keep in mind that use of
SOAPAction for dispatching is not a "standard". It is
meant to be a "hint".

 As mentioned by others in various threads, for
DOC/Lit I would recommend WSDL as the starting point
and design it so that reqest SOAP body contains an
<addRequest> document. (You would have to define a
corresponding complex type in your WSDL)

I think that when you use doc/lit operations, you
must provide a each with a
distinct SoapAction in the bindings, e.g.

wsdlsoap:soapAction="http://mycompany.com/mySubtract";

.

This might not be necessary if the Wrapped style is
used, but better to be
safe.

Given below ( the interface, the client, the
generated WSDL and the SOAP
messages generated).  When I use the generated
stubs, methods with the same
signature ( int add( int ) and int subtract( int ) )
are not distinguished
on the server side.  What happens is that add gets
called when subtract
should.  This seems like a bug?
Things work fine if I use RPC Encoded though. I am
using Axis 1.1 release
build.
