Change namespaceURI in request with SOAPHandler

Question

I try to change the body (the namespaceURI of a part the request) of a soap message with a SOAPHandler, but this seems not to work. The reason for the change is, that I have to work with different clients, and there is one old one which can not be changend, so I want to change this clients message to get it work with my Server.

Here is my code:

@Override
    public boolean handleMessage(SOAPMessageContext context) {

        boolean isResponse = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        try {
            if (!isResponse) {
                SOAPMessage msg = context.getMessage();
                SOAPBody body = msg.getSOAPBody();
                Iterator<?> iter = body.getChildElements();
                boolean implChanged = false;
                while (iter.hasNext()) {
                    Object next = iter.next();
                    if (next instanceof SOAPElement) {
                        SOAPElement se = (SOAPElement) next;
                        String uri = se.getNamespaceURI();
                        if (uri.equalsIgnoreCase("http://service.plr.mycomp.com/BruttoNettoRechner/1.0")) {
                            if (!se.removeNamespaceDeclaration("impl")) {

                                System.out.println("FEHLER beim entfernen");
                            }
                            if (se.addNamespaceDeclaration("impl", "http://service.plr.mycomp.com") == null) {
                                System.out.println("Fehler beim hinzufügen");
                            }
                            System.out.println(se.getNamespaceURI());
                            System.out.println(se.lookupNamespaceURI("impl"));

                            implChanged = true;

                        }
                    }
                }
                if (msg.saveRequired()) {
                    msg.saveChanges();
                }
                msg.writeTo(System.out);

            }
        } catch (SOAPException e) {
            System.out.println("SOAP FEHLER");
        } catch (IOException e) {
            e.printStackTrace();
        }

        return true;
    }

Here is the input:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <SOAP-ENV:Header/>

         </bruttoNettoIn>
      </impl:calculateBruttoNetto>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The console output says that the URI has not changed, but when I ask for the whole message it seems to work. But the WARNING after shows that nothing has changed:

So I dont understand why my change for the namespace is not working. (I dont expect that the message is working, there are other tasks to do).

thx

Answer 1

I did not find out why my code is not working, but I found a solution that covers my needs:

public boolean handleMessage(SOAPMessageContext context) {

    boolean isResponse = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
    try {
        if (!isResponse) {
            SOAPMessage msg = context.getMessage();
            SOAPBody body = msg.getSOAPBody();
            Iterator<?> iter = body.getChildElements();
            while (iter.hasNext()) {
                Object next = iter.next();
                if (next instanceof SOAPElement) {
                    SOAPElement se = (SOAPElement) next;
                    if (se.getNamespaceURI().equalsIgnoreCase("http://service.plr.mycomp.com/BruttoNettoRechner/1.0")) {
                        QName qName = new QName("http://service.plr.mycomp.com", "calculateBruttoNetto", "impl");
                        se.setElementQName(qName);
                        break;
                    }
                }
            }
            if (msg.saveRequired()) {
                msg.saveChanges();
            }
            // msg.writeTo(System.out);

        }
    } catch (SOAPException e) {
        log.error("Fehler beim Bearbeiten des Requests im ServerSOAPHandler", e);
    }

    return true;
}
