Question

I am trying to invoke a webservice method which takes 2 input parameters and also needs a cookie to authenticate.

        PostMethod method = new PostMethod("webservice EP URL");
        NameValuePair code = new NameValuePair("Code", "");
        NameValuePair revision = new NameValuePair("Rev", "Latest");

        NameValuePair targetUri = new NameValuePair("TARGET", "GetObject");
        method.setRequestBody(new NameValuePair[] { code, revision,targetUri});
        int statusNew = client.executeMethod(method);

I dont know how to achieve it. Above code is what i am doing currently.

Answer 1

Using the SOAP Handler, we can pass the headers in the request and it will do the job.

GetObject_Service_Impl impl = new GetObject_Service_Impl();
        // Get Iterator for all service ports
        Iterator iter = impl.getPorts();

        // Now create a new List of HandlerInfo objects - only one really.
        // Our client handler
        List handlerChain = new ArrayList();
        handlerChain.add(new HandlerInfo(SoapHandler.class, null, null));

        // Get Handler Registry
        HandlerRegistry registry = impl.getHandlerRegistry();
        // Register each port with the handler
        while (iter.hasNext())
            registry.setHandlerChain((QName) iter.next(), handlerChain);

And Write a new class say SoapHandler.java as below

public class SoapHandler extends GenericHandler {

HandlerInfo hi;

public void init(HandlerInfo info) {
    hi = info;
}

public QName[] getHeaders() {
    return hi.getHeaders();
}

public boolean handleResponse(MessageContext context) {

    return true;
}

/**
 * This method is use to add custom headers to existing SAOP request
 */
public boolean handleRequest(MessageContext context) {
    System.out.println("response");

    try {
        SOAPMessageContext smc = (SOAPMessageContext) context;
        SOAPMessage message = smc.getMessage();
        MimeHeaders hd = message.getMimeHeaders();
        hd.addHeader("Authorization", "Basic some credentials");

    } catch (Exception e) {
        throw new JAXRPCException(e);
    }
    return true;
}

}

And thats it…..its ready to go.
