    Invoking a web service from JBoss AS as a client

    Peter Schilling Newbie

      I've been trying to figure this out for several days, any help will be appreciated.

       

      I'm trying to invoke a web service from a java class deployed in JBoss 5.1.0.GA running on JDK1.6.0. I get the exception below. The same method called from a plain Java object and invoked from a command line (using JDK's WS jars instead of JBoss') works perfectly.

       

       

      I copied the jboss-native-* classes to the endorsed directory (initally to resolve the SetProperty problem), but is there anything else that needs to be considered to invoke a service from JBoss as a client?

       

      Three things that are different from the case when the method is invoked successfully from the command line:

        • In the request STDOUT the XML version header was removed (probably by SaveMessage).
        • In the request STDOUT quotes were converted to apostrophes.
        • Even thought the content type is set as text/xml, the error says content type is text/html

       

      Thanks for your help

      The method and the output/error:

       

       

      try {

       

                  // Create the SOAP connection

                  SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();

                  SOAPConnection connection = soapConnFactory.createConnection();

       

       

                   String soapText = 

                       "<?xml version=\"1.0\"?>" +

                      "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\"" + 

                       " SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">" + 

                       "<SOAP-ENV:Header/>" +

                       "<SOAP-ENV:Body>" +

                       "<Discover xmlns=\"urn:schemas-microsoft-com:xml-analysis\">" +

                       "<RequestType>DISCOVER_DATASOURCES</RequestType>" +

                       "<Restrictions><RestrictionList/></Restrictions>"  +

                       "<Properties><PropertyList><Format>Tabular</Format></PropertyList></Properties>"  +

                       "</Discover>"  +

                       "</SOAP-ENV:Body>" +

                       "</SOAP-ENV:Envelope>";

       

                   // Create SoapMessage 

                   MessageFactory msgFactory     = MessageFactory.newInstance(); 

                   SOAPMessage message           = msgFactory.createMessage(); 

       

                   // Load the SOAP text into a stream source 

                   ByteArrayInputStream stream   = new ByteArrayInputStream(soapText.getBytes()); 

                   StreamSource source           = new StreamSource(stream); 

       

                   // Set contents of message  

                   message.getSOAPPart().setContent(source); 

       

                   MimeHeaders mh = message.getMimeHeaders();

                   mh.setHeader("Content-Type", "text/xml");

                   mh.setHeader("SOAPAction", "\"urn:schemas-microsoft-com:xml-analysis:Discover\"");

                   //Save the message

                   message.saveChanges();

       

                  //Check the input

                  System.out.println("HEADERS:\n" );

                  Iterator<MimeHeader> i = message.getMimeHeaders().getAllHeaders();

       

                  while ( i.hasNext() ) {

                      MimeHeader header = i.next();

                      String name = header.getName();

                      String value = header.getValue();

                      System.out.println ( name + ": " + value);

                  }

                  System.out.println("END HEADERS:\n" );

       

       

                  System.out.println("REQUEST:\n");

                  message.writeTo(System.out);

                  System.out.println("END REQUEST:\n");

       

                  //Send the message and get a reply  

       

                  //Set the destination

                  String destination = "http://localhost:7070/mondrian/xmla";

                  //Send the message

                  SOAPMessage reply = connection.call(message, destination);

       

                  //Check the reply

                  System.out.println("\nREPLY:\n");

                  reply.writeTo(System.out);

                  System.out.println("\nEND REPLY:\n");

       

                  // Close the SOAP connection           

                  connection.close();

       

              } catch(Exception e) {

                  System.out.println(e.getMessage());

              }

       

          }
