Exemple de client de Working Soap

J'essaie de trouver un exemple simple (ha) SOAP en JAVA avec un service fonctionnel, tout ce que je semble trouver ne fonctionne pas.

J'ai essayé celui- ci à partir de cet exemple, mais cela ne fonctionne tout simplement pas, il me demande de mettre une barre oblique, mais il est là et rien ne se passe.

Alors, est-ce que quelqu'un connaît des exemples de liens SOAP, je peux télécharger / demander et jouer avec?

Merci de votre aide.

Pour implémenter des clients SOAP simples en Java, vous pouvez utiliser le framework SAAJ (il est livré avec JSE 1.6 et supérieur):

L'API SOAP avec pièces jointes pour Java (SAAJ) est principalement utilisée pour traiter directement les messages de demande / réponse SOAP qui se produisent dans les coulisses de toute API de service Web. Il permet aux développeurs d'envoyer et de recevoir directement des messages soap au lieu d'utiliser JAX-WS.

Voir ci-dessous un exemple fonctionnel (exécutez-le!) D'un appel de service Web SOAP utilisant SAAJ. Il appelle ce service Web .

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*
            The example below requests from the Web Service at:
             http://www.webservicex.net/uszip.asmx?op=GetInfoByCity


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "http://www.webservicex.net/uszip.asmx";
        String soapAction = "http://www.webserviceX.NET/GetInfoByCity";

        callSoapWebService(soapEndpointUrl, soapAction);

        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

Oui, si vous pouvez acquérir un fichier WSDL, vous pouvez utiliser SoapUI pour créer un service simulé de ce service avec des demandes de test unitaire. J'ai créé un exemple de cela (en utilisant Maven) que vous pouvez essayer .

La réponse d'acdcjunior était géniale, je viens d'étendre son explication avec le code suivant, où vous pouvez voir comment itérer sur les éléments XML.

public class SOAPClientSAAJ {

public static void main(String args[]) throws Exception {
    // Create SOAP Connection
    SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
    SOAPConnection soapConnection = soapConnectionFactory.createConnection();

    // Send SOAP Message to SOAP Server
    String url = "http://ws.cdyne.com/emailverify/Emailvernotestemail.asmx";
    SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);



    SOAPPart soapPart=soapResponse.getSOAPPart();
    // SOAP Envelope
    SOAPEnvelope envelope=soapPart.getEnvelope();
    SOAPBody soapBody = envelope.getBody();

    @SuppressWarnings("unchecked")
    Iterator<Node> itr=soapBody.getChildElements();
    while (itr.hasNext()) {

        Node node=(Node)itr.next();
        if (node.getNodeType()==Node.ELEMENT_NODE) {
            System.out.println("reading Node.ELEMENT_NODE");
            Element ele=(Element)node;
            System.out.println("Body childs : "+ele.getLocalName());

            switch (ele.getNodeName()) {

          case "VerifyEmailResponse":
             NodeList statusNodeList = ele.getChildNodes();

             for(int i=0;i<statusNodeList.getLength();i++){
               Element emailResult = (Element) statusNodeList.item(i);

Pour l'authentification de base de WSDL, le code de réponses acceptées génère une erreur. Essayez plutôt ce qui suit

Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("username","password".toCharArray());
    }
});

    "        <soap:Body>\n" +
    "        </soap:Body>\n" +
    "</soap:Envelope>";

private static String getResponse(String send) throws Exception {
    String url = "https://api.comscore.com/KeyMeasures.asmx"; //endpoint
    String result = "";
    String username="user_name";
    String password="pass_word";
    String[] command = {"curl", "-u", username+":"+password ,"-X", "POST", "-H", "Content-Type: text/xml", "-d", send, url};
    ProcessBuilder process = new ProcessBuilder(command); 
    Process p;
    try {
        p = process.start();
        BufferedReader reader =  new BufferedReader(new InputStreamReader(p.getInputStream()));
        StringBuilder builder = new StringBuilder();
        String line = null;
        while ( (line = reader.readLine()) != null) {
                builder.append(line);
                builder.append(System.getProperty("line.separator"));
        }
        result = builder.toString();

        e.printStackTrace();
    }
