Question

I want to call a webservice from a J2ME application :

public String alimenterBaseDeDonneesEtapeProsp( String login, String password,String adresse,String site)
    {
        Object  resultatRequeteSOAP = null;
        SoapObject objetSOAPEtapeProsp;
        HttpTransport connexionServeur;
        SoapSerializationEnvelope envelope;
        String nomService = "urn:Client";
        String urlService = adresse+"/"+site+"/webservice/InterfaceTransfererClient.php";
        String methodeChoisie = "getEtapeProsp";
        try
        {
                    connexionServeur = new HttpTransport(urlService );
                    connexionServeur.debug = true;
                    objetSOAPEtapeProsp = new SoapObject(nomService, methodeChoisie );
                    objetSOAPEtapeProsp.addProperty("user", login);
                    objetSOAPEtapeProsp.addProperty("motpasse",password);
                    System.out.println(objetSOAPEtapeProsp);
                    envelope = new SoapSerializationEnvelope(SoapSerializationEnvelope.VER11);
                    envelope.bodyOut = objetSOAPEtapeProsp;
                    connexionServeur.call(null,envelope);
                    resultatRequeteSOAP = envelope.getResponse();
                    return String.valueOf(resultatRequeteSOAP);
        }
        catch (Exception aE)
        {
             return aE.getMessage();
        }
    }

The ksoap2-j2me-core-2.1.2.jar file is already added to the J2ME project.

The wsdl file is :

The PHP code containing the function which the webservice calls is :

<?php
    header('Content-Type: text/plain; charset=utf-8');
    ini_set("soap.wsdl_cache_enabled", "0");
    $serveurSOAP = new SoapServer('Client.wsdl');

    $serveurSOAP->addFunction('getModificationCredit');
    $serveurSOAP->addFunction('getModificationEcheance');
    $serveurSOAP->addFunction('getAllPhotoNames');
    $serveurSOAP->addFunction('getEtapeProsp');
    if ($_SERVER['REQUEST_METHOD'] == 'POST')
    {
         $serveurSOAP->handle();
    }
    else
    {
         echo 'désolé, je ne comprends pas les requêtes GET, veuillez seulement utiliser POST';
    }
        ...
        function verifyUser($user, $motpasse) {
        $ok = null ;
        $connec = mysql_connect("192.168.1.123:3306", "root", "mysqlroot");
        mysql_select_db("finance",$connec);
        $query=mysql_query("SELECT  user_code FROM utilisateur WHERE user_login = '".$user."' AND user_passwd = md5('".$motpasse."')");
        if (mysql_num_rows($query)== 1) 
        {
            $ligne = mysql_fetch_array($query);
            $ok = $ligne['user_code'] ;
        }   
        return $ok;
    }
        ...
        function getEtapeProsp($user,$motpasse)
    {
        $user_code    = verifyUser($user, $motpasse) ;
        $resultat="";
        if ( $user_code != null) 
        {
            $datejour = date("Y-m-d");

            while($ligne = mysql_fetch_array($query))

                     $resultat .= $ligne['etape_prosp_id'].';';

        }
        return $resultat;
    }
?>

As you can see I set the encoding/charset both in the wsdl and the PHP.

So why this exception is raised when running the J2ME application :

expected: END_TAG {http://schemas.xmlsoap.org/soap/envelope/}Body (position:END_TAG </{http://schemas.xmlsoap.org/soap/envelope/}SOAP-ENV:Fault>@2:299 in java.io.InputStreamReader@e5125d64)

Answer 1

You need to tell your mysql database / client that you expect to have UTF-8 encoded values (because you insert them as UTF-8 into the SOAP response that is UTF-8 encoded).

Otherwise the SOAP client would see an invalid byte-squence for the letter in question and throw the exception. Please consult your mysql client library manual to specify the encoding.

$connec = mysql_connect("192.168.1.123:3306", "root", "mysqlroot");
mysql_set_charset('utf8', $connec);

The mb_convert_encoding function is only a workaround and you don’t fix the root cause, and it can have side-effects you don’t want to have.
