[Axis2] Sending or receiving unnamed parameter arrays/lists with Axiom,ADB in Axis2 client

["Pantvaidya, Vishwajit" <vp...@selectica.com>]

I need to dynamically call any given webservice using its wsdl provided as a parameter. Since I do not know the signature of the service, I need to be able to provide for sending or receiving parameter arrays/lists. So I have coded a client which creates a payload by adding a number of children to an OMElement i.e

OMNamespace ns = fac.createOMNamespace(operationNamespace, "ns1");
payload = fac.createOMElement(operationName, ns);
for (each parameter value) {
OMElement value = fac.createOMElement(parameterName, ns);
value.addChild(fac.createOMText(value, parameterValue.toString()));
payload.addChild(value);
}

Is this correct?

And do I absolutely need to provide parameter names as in the call "OMElement value = fac.createOMElement(parameterName, ns)" or is their another way by which I can only provide a list of input param values and have them associated with the webservice parameters based on position rather than name?

Hi,

If you are constructing the payload, you need to do the way which is specified by the WSDL of the service. For example, the pay load of a request which will be sent to a particular Web service operation will differ depending on the style it uses (document, rpc) and the encoding (literal, encoded).
So I am not sure whether you can achieve that by just including the parameter names and values as child elements of a parent with operation name.

Best,
