Working Soap client example

问题:

I\'m trying to find a simple (ha) SOAP example in JAVA with a working service, any I seem to be finding are not working.

I have tried this one from this example but it\'s just not working, it\'s asking me to put a forward slash in but it\'s in there and nothing happening.

So does anyone know any SOAP example links, I can download/request and mess with?

Thanks for your help.

To implement simple SOAP clients in Java, you can use the SAAJ framework (it is shipped with JSE 1.6 and above):

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

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);
    }

    private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String myNamespace = \"myNamespace\";
        String myNamespaceURI = \"http://www.webserviceX.NET\";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

            /*
            Constructed SOAP Request Message:
            <SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:myNamespace=\"http://www.webserviceX.NET\">

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement(\"GetInfoByCity\", myNamespace);
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement(\"USCity\", myNamespace);
        soapBodyElem1.addTextNode(\"New York\");
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl);

            // Print the SOAP Response
            System.out.println(\"Response SOAP Message:\");
            soapResponse.writeTo(System.out);
            System.out.println();

            soapConnection.close();
        } catch (Exception e) {
            System.err.println(\"\\nError occurred while sending SOAP Request to Server!\\nMake sure you have the correct endpoint URL and SOAPAction!\\n\");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();

        createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader(\"SOAPAction\", soapAction);

        soapMessage.saveChanges();

        /* Print the request message, just for debugging purposes */
        System.out.println(\"Request SOAP Message:\");
        soapMessage.writeTo(System.out);
        System.out.println(\"\\n\");

        return soapMessage;
    }

}

Yes, if you can acquire any WSDL file, then you can use SoapUI to create mock service of that service complete with unit test requests. I created an example of this (using Maven) that you can try out.

Also, here is a giant list of free webservices someone posted.

The response of acdcjunior it was awesome, I just expand his explanation with the next code, where you can see how iterate over the XML elements.

For Basic Authentication of WSDL the accepted answers code raises an error. Try the following instead

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