problem calling web service from j2me app

[mmartins]

Greetings,
I have been trying to run a j2me application using ksoap2 to access a web service. Thus far I have been unable to do so, due to some error in the call I am making to the service. I was wondering if anyone could spot what I have done wrong in the call:

This is the expected soap body for the web service:

<authenticateUser xmlns="http://www.openuri.org/">
<!--Optional:-->
<info>
<!--Optional:-->
<userID>test</userID>
<!--Optional:-->
<password>password</password>
<resultCode>3</resultCode>
<!--Optional:-->
<message>string</message>
</info>
</authenticateUser>


This is the code I am using to call the web service from the midlet:

SoapObject rpc = new SoapObject("http://localhost:7001/BasicAppWeb/MyWebServices","authenticateUser");
rpc.addProperty("info", info);


SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);
envelope.bodyOut = rpc;

HttpTransport ht = new HttpTransport("http://localhost:7001/BasicAppWeb/MyWebServices/AuthenticationService.jws");

This is the response (error) I am receiving from the server:

<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

This is how my message is being formatted:

<v:Header />
<v:Body>

<info i:type=":AuthInfo">
<userID i:type="d:string">test</userID>
<password i:type="d:string">password</password>
</info>
</n0:authenticateUser>
</v:Body>
</v:Envelope>

Thanks in advance for any help, I have been struggling with this one for a bit.

Thanks!

Are you sure that your "BasicAppWeb/MyWebServices" is implementing the "authenticateUser" method?

[mmartins]

Thank you for the response axs, this is the first time i am working with web services so i think my confusion lies in how i am calling the service.

the structure of the web service i am calling is the following:
the wsdl is:
http://localhost:7001/BasicAppWeb/My...eContract.wsdl
the jws:
http://localhost:7001/BasicAppWeb/My...ionService.jws

this is the wsdl for the service:

<?xml version="1.0" encoding="utf-8"?>
<!-- @editor-info:link autogen="true" source="AuthenticationService.jws" -->
<wsdl:definitions xmlns:conv="http://www.openuri.org/2002/04/soap/conversation/" xmlns:cw="http://www.openuri.org/2002/04/wsdl/conversation/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:jms="http://www.openuri.org/2002/04/wsdl/jms/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:s0="http://www.openuri.org/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://www.openuri.org/">

</wsdl:service>
</wsdl:definitions>


i am a bit confused as to what i have to pass as the namespace of the soap object, currently i am formatting it like so:

SoapObject info = new SoapObject("","AuthInfo");
info.addProperty("userID", "test");
info.addProperty("password", "password");

SoapObject rpc = new SoapObject("http://localhost:7001/BasicAppWeb/MyWebServices","authenticateUser");
rpc.addProperty("info", info);


then i call the web service like so:

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);
envelope.bodyOut = rpc;

HttpTransport ht = new HttpTransport("http://localhost:7001/BasicAppWeb/MyWebServices/AuthenticationService.jws");


i am guessing i am doing something wrong in the call, i would appreciate any help just understand how these calls should be made and what parameters i have to send.

thanks again!

Hi,

Did you find a solution for this? Can you post it here please.

Hi mmartins,

You just try to use one developing simple tool at http://sourceforge.net/projects/ksoap2genstub/. The tool helps you to generate code in J2ME from the WSDL document so that you can easily invoke web services in J2ME.
