hi Don;
you can write a client to consume a web service where web service only
contains service.xml (no wsdl file is present) , in that case you have to
create the SOAPMessge by hand , use one of the MEPClient to send the request
. And all these has to handle in the your client code since you do not have
stubs. In fact in M2 we have don that.and I think following code will help
you to do so , and which invoke the version service.
private String value;
private QName operationName = new QName("getVersion");
private OMElement createEnvelope() {
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs = fac.createOMNamespace("http://localhost/my";,
"my");
OMElement method = fac.createOMElement("Version", omNs);
OMElement value = fac.createOMElement("myValue", omNs);
method.addChild(value);
return method;
}
public boolean inVokeTheService() {
try {
OMElement payload = createEnvelope();
Call call = new Call();
call.setTo(targetEPR);
call.setTransportInfo(Constants.TRANSPORT_HTTP,
Constants.TRANSPORT_HTTP, false);
OMElement result =
(OMElement)
call.invokeBlocking(operationName.getLocalPart(), payload);
StringWriter writer = new StringWriter();
result.serializeWithCache(new
OMOutput(XMLOutputFactory.newInstance().createXMLStreamWriter(writer)));
writer.flush();
value = writer.toString();
return true;
} catch (AxisFault axisFault) {
value = axisFault.getMessage();
return false;
} catch (XMLStreamException e) {
value = e.getMessage();
return false;
}
}

Subject: Re: [axis 2]Questions on the development process using Axis 2.0
Hi, Chathura,
Thank you for your reply to my questions. Now I understand the
purposes of the different parts in the user guide of axis 2.
I like the approach that using the java classes and the service.xml to
deploy web services. But I am still thinking how to develop clients to
consume such services, if no wsdls are present. Is it possible to
develop a client just based on the service.xml?
Cheers,
Don

This is an sample with no data binding(Note it echo's the OMElement. This
was the sample we had for M2 where we didn't have databinding support) So
if
the user want to be smart and do everyting manually that's the way to do
it.
This example will tell you what are the must have's if you are to make it
work.

You of course can write it by hand, the sample is based on the fact that
you
start with the contract, which is the wsdl. But.. we have a tool that does
the java2wsdl part. Actually we use the Axis1 java2wsdl tool and I belive
we
have a eclipse pluigin for that too. Am I right Ajith???
> 3. what is the relationship between the first aar and the second one?
No relationship.. The second one is a databound (a more comprehensive and
practical I would say) example that emphasize the axis2 data binding
support.
In a nut shell we are not trying to invent a new development process. (But
we have our own deployment model, programming model too I would say..)
Thanks
