I'm trying to implement two clients for an Axis message service. One is for a j2se client and the other is j2me client. However I cannot use the same service for both of the clients. I will tell my problem using basic codes.

J2ME Axis message-style web service code:

1 public synchronized Element[] echoElements(Element[] params)
2 {
3 NodeList nodeList = params[0].getChildNodes();
4
5 String elem0 = nodeList.item(1).getTextContent();
6 String elem1 = nodeList.item(3).getTextContent();
7
8 SOAPBodyElement[] message = new SOAPBodyElement[1];
9 message[0] = new SOAPBodyElement(XMLUtils.StringToElement("", "message", ""));
10
11 message[0].appendChild(new SOAPBodyElement(XMLUtils.StringToElement("urn:foo", "e0", "1:"+elem0)));
12 message[0].appendChild(new SOAPBodyElement(XMLUtils.StringToElement("urn:foo", "e1", "2:"+elem1)));
13
14 SOAPBodyElement[] result = new SOAPBodyElement[1];
15 result[0] = new SOAPBodyElement(XMLUtils.StringToElement("", "result", ""));
16
17 result[0].appendChild(message[0]);
18
19 return result;
20 }

As you can see at lines 5 and 6 I can only take parameters giving indeces 1 and 3 for a mobile client.

A part of theJ2ME client code:

try {
    SoapObject client = new SoapObject("urn:foo","echoElements");
                       
    client.addProperty("e1","elem1");
    client.addProperty("e2","elem2");
            
    HttpTransport ht = new HttpTransport("http://localhost:8080/axis/services/MessageService","urn:foo");
            
    SoapObject so = (SoapObject)ht.call(client);
            
    System.out.println("arg0: "+so.getProperty(0));
    System.out.println("arg1: "+so.getProperty(1));
} catch(Exception ex) {
    System.out.println("Exception:");
    ex.printStackTrace();
}


J2SE Axis message-style web service code:

5 String elem0 = nodeList.item(0).getTextContent();
6 String elem1 = nodeList.item(1).getTextContent();

The same code except the lines 5 and 6. I can only take parameters giving indeces 0 and 1 for a console client.

I don't understand why I have to change the indeces (1,3 for mobile - 0,1 for console)

The Soap message is:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema " xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
    <message xmlns="">
      <e1 xmlns="urn:foo">1:elem1</e1>
      <e2 xmlns="urn:foo">2:elem2</e2>
    </message>
</soapenv:Body>
</soapenv:Envelope>


Please can you tell me why?
