How to call SAP web service in Java?

[Former Member]

I have a RFC-enabled function in sap (WebService).. I want to call this function and get the result using java. What should I do? (I already have the WSDL endpoint)

Hi ,

If you use eclipse you can use the built in facility to consume the web service (Use the EE version).

The wsdl will be used as input -

Search the web how to create web service client in eclipse .

To test the service you can use soapui http://www.soapui.org/

Also look at Apache Axis2 - Apache Axis2/Java - Next Generation Web Services

Hi,

Thanks for your reply, but I want to create a Java application, not a web application .. does it work too ?

[rosenberg_eitan]

Hi,

You just need the generated Java Code .

.

It is a regular desktop app .

Hi,

Please run the below java program to test the web service.

you can specify your end point details and execute your method.

package com.an.edu.SOAPtest;

import javax.xml.soap.*;

import javax.xml.transform.*;

import javax.xml.transform.stream.*;

public class SOAPClientSAAJ {

    /**

     * Starting point for the SAAJ - SOAP Client Testing

     */

    public static void main(String args[]) {

        try {

            // 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);

            // Process the SOAP Response

            printSOAPResponse(soapResponse);

            soapConnection.close();

        } catch (Exception e) {

            System.err.println("Error occurred while sending SOAP Request to Server");

            e.printStackTrace();

        }

    }

    private static SOAPMessage createSOAPRequest() throws Exception {

        MessageFactory messageFactory = MessageFactory.newInstance();

        SOAPMessage soapMessage = messageFactory.createMessage();

        SOAPPart soapPart = soapMessage.getSOAPPart();

        String serverURI = "http://ws.cdyne.com/";

        // SOAP Envelope

        SOAPEnvelope envelope = soapPart.getEnvelope();

        envelope.addNamespaceDeclaration("example", serverURI);

        // SOAP Body

        SOAPBody soapBody = envelope.getBody();

        SOAPElement soapBodyElem = soapBody.addChildElement("VerifyEmail", "example");

        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("email", "example");

        soapBodyElem1.addTextNode("nautiyal.anil@gmail.com");

        SOAPElement soapBodyElem2 = soapBodyElem.addChildElement("LicenseKey", "example");

        soapBodyElem2.addTextNode("123");

        MimeHeaders headers = soapMessage.getMimeHeaders();

        headers.addHeader("SOAPAction", serverURI  + "VerifyEmail");

        soapMessage.saveChanges();

        /* Print the request message */

        System.out.print("Request SOAP Message = ");

        soapMessage.writeTo(System.out);

        System.out.println();

        System.out.print("Getting SOAP response");

        return soapMessage;

    }

    /**

     * Method used to print the SOAP Response

     */

    private static void printSOAPResponse(SOAPMessage soapResponse) throws Exception {

    System.out.print("Getting SOAP response");

        TransformerFactory transformerFactory = TransformerFactory.newInstance();

        Transformer transformer = transformerFactory.newTransformer();

        Source sourceContent = soapResponse.getSOAPPart().getContent();

        System.out.print("\nResponse SOAP Message = ");

        StreamResult result = new StreamResult(System.out);

        transformer.transform(sourceContent, result);

    }

}

Hi,

Thank you for you reply, I have already could print the response xml, but how parse the result rather than only display the xml ?
