Can AXIS2 and WSTK work together?
lazarus / 38-Networking and Web Programming

I have an AXIS2 SOAP webservice that correctly works with a Java
client.
It's a webservice that receives an input string and returns an output
string.
I used the Web Service Toolkit to generate the stubs for a a Lazarus
SOAP client.

Now calling the webservice works (AXIS2 logs the call) and the
returned SOAP message is correctly received by the Lazarus webservice
stub.
Unfortunately the generated stubs do not parse the SOAP message
correctly.
The parser doesn't correctly parse namespaces in the soap Body.
This seems to be related to a problem already mentioned here.

Is there a workaround for this problem?
I.e. is it possible to call an AXIS2 webservice with Lazarus?

<<update>>

The problem lies in the parser. The parser tries to resolve the
namespace url in the response, but searches too high up in the tree.
Below is the SOAP reply message:

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
    <ns:sayHelloResponse xmlns:ns="http://service.eny.com">
      <ns:return>Howdy eny!</ns:return>
    </ns:sayHelloResponse>
  </soapenv:Body>
</soapenv:Envelope>

The parser tries to resolve the namespace url
"http://service.eny.com".
But parsing starts with node <soapenv:Body> and then goes up.
Of course nothing is found then.

Hi Eny,

I'm trying to make a client to consume a webservies lazarus of Axis2,
but I find the same problem.
Find solutions to this problem?

Well, yes and no 
The toolkit doesn't work so I stopped using it.
I was in the process of building a GUI frontend with Lazarus to a SOAP
backend server on Linux.
The logical/easiest solution at the time seemed to go for a Java/AXIS2
backend.
But after disappointing results and extensive debugging I abandoned
that idea.
Also I didn't like the messy code that was generated by the toolkit.

I decided to go for the most flexible solution: build my own (SOAP)
backend with Synapse. This was only possible because of Lazarus' 
availability for Linux.
The PoC works and now I'm working on a code generator for client and
server side message parsing.
(Although because of other projects I have had to pause this for a
while   )
