RE: Passing XML to webservice?

[Warrell]

Hi Ant,   Funny you should ask that. I have just written a custom transformer to do that! I first adapted the WSProxyGenerator  to set the SoapAction header but being a generator was a bit too restrictive. I was hoping to add the new transformer into the development stream but have been too busy using it. Mostly complete source code below – mostly taken from the WSProxyGenerator.java but for a DOMTransformer. It uses dom4j which feels like cheating but times are tough…..     public class WSProxy extends AbstractDOMTransformer { private String configuredSoapAction = null; private HttpClient httpClient = null;   private static final String HTTP_CLIENT = "HTTP_CLIENT"; private static final String SOAP_ACTION = "SOAPAction";   public void setup(SourceResolver resolver, Map objectModel, String src, Parameters par) throws ProcessingException, SAXException, IOException {             super.setup(resolver,objectModel,src,par);             try             {                         Source inputSource = resolver.resolveURI(super.source);                         this.source = inputSource.getURI();             }             catch(SourceException se)             {                         throw SourceUtil.handle("Unable to resolve " + super.source, se);             }             this.configuredSoapAction = par.getParameter("soap-action", new String());             this.httpClient = this.getHttpClient(); }   protected org.w3c.dom.Document transform(org.w3c.dom.Document document) {             InputStream soapResponse;             org.w3c.dom.Document doc;               PostMethod post = new PostMethod(this.source);             try             {                         post.setRequestHeader(new Header(SOAP_ACTION, this.configuredSoapAction));                         org.dom4j.Document domj = new DOMReader().read(document);                           post.setRequestBody(domj.asXML());                         // Get HTTP client                         HttpClient httpclient = new HttpClient();                         // Execute request                         int result = httpclient.executeMethod(post);                         soapResponse = post.getResponseBodyAsStream();                         doc = parse(soapResponse);             }             catch(Exception e)             {                         this.getLogger().error("SOAP_ACTION: " + this.configuredSoapAction + " Failed");                         return WSProxyUtility.reportErrorAsDOM(e);             }             finally             {                         // Release current connection to the connection pool once you are done                         post.releaseConnection();             }               return doc; }     /**  * Create one per client session  */ protected HttpClient getHttpClient() throws ProcessingException {             URI uri = null;             String host = null;             Request request = ObjectModelHelper.getRequest(objectModel);             Session session = request.getSession(true);             HttpClient httpClient = null;             if (session != null)             {                         httpClient = (HttpClient)session.getAttribute(HTTP_CLIENT);             }             if (httpClient == null)             {                         httpClient = new HttpClient();                         HostConfiguration config = httpClient.getHostConfiguration();                         if (config == null)                         {                                     config = new HostConfiguration();                         }                           /* TODO: fixme!                          * When the specified source sent to the wsproxy is not "http"                          * (e.g. "cocoon:/"), the HttpClient throws an exception.  Does the source                          * here need to be resolved before being set in the HostConfiguration?

  Hi,   In the sitemap, how do you pass the XML produced from a transformer onto an external web service:   <map:match pattern="create_order"> <map:generate src="">             <map:transform src="">              SEND TO WEBSERVICE HERE! </map:match>   Many thanks in advance, Ant
