RE: calling external SOAP service from Ofbiz

Hi,

I use Smooks to deal with conversion xml -> Java objects when consuming a
webservice. Hope it helps.

Regards,
Fairuz

Hello,

This is the solution I finally got. I hope it will be helpful for people
having the same problem as I had.

1) In my events java class I wrote the following code (which is an event
calling the method that deals with SOAP):

*       
public static String callMySoap(HttpServletRequest
request,HttpServletResponse response)
  {     
    request.setAttribute("_EVENT_MESSAGE_", "You received this SOAP
response:" + MySoapClient());
    return "success";
  }     
        

        
public static SOAPMessage MySoapClient()
    {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory =
SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection =
soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server
            String url = "http://www.webservicex.net/geoipservice.asmx";;
            SOAPMessage soapResponse =
soapConnection.call(createSOAPRequest(), url);

            soapConnection.close();
            return soapResponse;
        } catch (Exception e) {
            System.err.println("Error occurred while sending SOAP Request to
Server");
            e.printStackTrace();
            return null;
        }       
        
    }

    private static SOAPMessage createSOAPRequest() throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String serverURI = "http://www.webservicex.net/";;

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration("web", serverURI);

        /*
        Constructed SOAP Request Message:
        <SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:example="http://www.webservicex.net/";>
            <SOAP-ENV:Header/>
            <SOAP-ENV:Body>
                <web:GetGeoIP>
                    <web:IPAddressl>192.168.1.2</web:IPAddress>
                </web:GetGeoIP>
            </SOAP-ENV:Body>
        </SOAP-ENV:Envelope>
         */

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("GetGeoIP",
"web");
        SOAPElement soapBodyElem1 =
soapBodyElem.addChildElement("IPAddress", "web");
        soapBodyElem1.addTextNode("192.168.1.2");

        
        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", serverURI  + "GetGeoIP");

        soapMessage.saveChanges();

        /* Print the request message */
        System.out.print("Request SOAP Message = ");
        soapMessage.writeTo(System.out);
        System.out.println();

        return soapMessage;
    }
*

2) I added the following request-map to point to my event:

*    
      <request-map uri="callMySoap">
      <event type="java" path="org.ofbiz.testapp.testapp.LearningEvents"
invoke="callMySoap"/>
      <response name="success" type="view" value="FeedbackMessages"/>
    </request-map>
*

3) I added the following view-map:

*
<view-map name="FeedbackMessages" type="screen"
page="component://testapp/widget/TestAppScreens.xml#FeedbackMessages"/>
*

which points to the following screen widget:
*
    <screen name="FeedbackMessages">
      <section>
        <widgets>
          <decorator-screen name="main-decorator"
location="${parameters.mainDecoratorLocation}">    
            <decorator-section name="title">
              <label text="Exploring all placeholders for Feedback"/>
            </decorator-section>
            <decorator-section name="body">
               
            </decorator-section>
          </decorator-screen>
        </widgets>
      </section>
    </screen>
*


Note:
 step 3 is not necessary. I only used it to see something on my screen.


Result:
 I can now see in real time the SOAP message that is being sent & the
response that is received.
and I can also this screen:
<http://ofbiz.135035.n4.nabble.com/file/n4646047/result.png> 


Now:
 the only thing I still need to do is some parsing on the SOAP response
message to be able to deal with the variables that interest me in that
message. I also need to enhance my code to make it more "generic" so that it
becomes somewhat dynamic and works with not only that specific Web Service
that I had to hardcode.

Do you have any suggestions for that? I do not want to be reinventing the
wheel!
