Consume Axis2 webservice from .net

Question

Created a new web service client for axis2 webservice on my .net application. Calling some methods of webservice. .Net is calling webservice and read xml response but can not deserialize it. Generated proxy code is normally for .net, its ok. wsdl is passed wsi compliance.

With wireshark i saw xml response is very normal. web service is responses the request normally but xml data is seem wrongly. let me show same data and contracts.

xml response:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
    <ns:blablaResponse xmlns:ns="http://blabla">
      <ns:return type="blablaMessage" xmlns:ax274="http://blabla/xsd" xmlns:ax272="http://blabla/xsd" xmlns:ax271="http://blabla/xsd">
        <ax274:blablaNo>1</ax274:blablaNo>
        <ax274:blablaNo>2</ax274:blablaNo>
        <ax274:blablaNo>3</ax274:blablaNo>
        <ax274:blablaDescription>TEXT 1</ax274:blablaDescription>
        <ax274:blablaDescription>TEXT 2</ax274:blablaDescription>
        <ax274:blablaDescription>TEXT 3</ax274:blablaDescription>
        <ax274:statustype="blblaState">
          <ax272:textMessage/>
          <ax272:code>OK</ax272:code>
        </ax274:status>
      </ns:return>
    </ns:blablaResponse>
  </soapenv:Body>
</soapenv:Envelope>

Tried wsdl.exe svcutil.exe with some various parameters thats all failed. It's seem a serialization problem with axis2 because different kind of elements in same xml parent. For example blablaNo and blablaDescription.

How can i solve this problem. Thanks.

Answer 1

publisher sent is to new wsdl file and problem is solved.

Answer 2

As per the XML response your showing it is strange, blablaNo for me isn't a array of int but i read it as 3 int variables and they don't seems to have distinguishable names. Never seen XML formated like that but i never worked with Java service output before either.

You know, if i were you i would try to change the output of the Axis service to JSON. First it would be smaller and secondly it would completely remove confusion over output formatting. to De-serialize JSON in .net is really easy.

Here's a very simple example i am currently working on (3 differents service communication with each other and PHP page and .Net desktop app)

internal class CFingerPrint
{
    public string WanIP;
    public string MacAddress;      

    public string getClassEncrypted()
    {
        return new JavaScriptSerializer().Serialize(this);
    }

    public CFingerPrint getClassDecrypted(string sSerializedClass)
    {
        return new JavaScriptSerializer().Deserialize<CFingerPrint>(sSerializedClass);
    }
}

In JSON you don't need the fancy attributes everywhere for basic properties. Unless you return custom object you should be fine.
