    <p>I'm fairly new to webservices and working through a SAAJ example of sending and recieving attachments (binary files). I can get it to work when the client sends the file but not when it requests it. I get an exception on the client side:<br> ERROR: 'Content is not allowed in prolog.' 24-Oct-2012 13:59:28 com.sun.xml.internal.messaging.saaj.soap.EnvelopeFactory createEnvelope SEVERE: SAAJ0511: Unable to create envelope from given source com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: Unable to create envelope from given source</p> <p>Anybody have any ideas???my client code is as follows: </p> <pre><code>SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance(); SOAPConnection con = scf.createConnection(); SOAPFactory soapFactory = SOAPFactory.newInstance(); MessageFactory mf = MessageFactory.newInstance(); SOAPMessage msg = mf.createMessage(); SOAPHeader header = msg.getSOAPHeader(); header.detachNode(); SOAPBody body = msg.getSOAPBody(); Name bodyName = soapFactory.createName( "remoteOpen", "remoteOpen", "http://schemas.remoteOpen.com/remoteOpen"); SOAPBodyElement bodyElement = body.addBodyElement(bodyName); SOAPElement projectName = bodyElement.addChildElement("projectName"); projectName.addTextNode("filename"); msg.saveChanges(); // create the endpoint and send the message URL endpoint = new URL("http://localhost:8080/RemoteSaveProject/OpenServlet"); SOAPMessage response = con.call(msg, endpoint); con.close(); SOAPBody responseBody = response.getSOAPBody(); SOAPElement ackElem = (SOAPElement)responseBody.getFirstChild(); String acknowledgement = ackElem.getValue(); </code></pre> <p>the server code looks like this: </p> <pre><code>MimeHeaders mimeHeaders = new MimeHeaders(); Enumeration en = request.getHeaderNames(); while (en.hasMoreElements()) { String headerName = (String)en.nextElement(); String headerVal = request.getHeader(headerName); StringTokenizer tk = new StringTokenizer(headerVal, ","); while (tk.hasMoreTokens()){ mimeHeaders.addHeader(headerName, tk.nextToken().trim()); } } SOAPMessage message = mf.createMessage(mimeHeaders, request.getInputStream()); SOAPBody body = message.getSOAPBody(); Name bodyName = soapFactory.createName( "remoteOpen", "remoteOpen", "http://schemas.remoteOpen.com/remoteOpen"); Iterator projects = body.getChildElements(bodyName); SOAPElement project = (SOAPElement)projects.next(); Iterator projectNameIter = project.getChildElements(soapFactory.createName("projectName")); SOAPElement projectNameEle = (SOAPElement)projectNameIter.next(); String projectName = projectNameEle.getValue(); File file = new File(projectName); SOAPMessage reply = mf.createMessage(); SOAPHeader header = reply.getSOAPHeader(); header.detachNode(); SOAPBody replyBody = reply.getSOAPBody(); SOAPBodyElement bodyElement = replyBody.addBodyElement(soapFactory.createName("ack")); bodyElement.addTextNode("OK"); DataHandler dh = new DataHandler(new FileDataSource(file)); AttachmentPart attachment = reply.createAttachmentPart(dh); attachment.setContentId("123"); reply.addAttachmentPart(attachment); reply.saveChanges(); response.setStatus(HttpServletResponse.SC_OK); putHeaders(reply.getMimeHeaders(), response); response.setContentType("text/xml"); ServletOutputStream replyOS = response.getOutputStream(); reply.writeTo(replyOS); replyOS.flush(); replyOS.close(); </code></pre> <p>putHeaders looks like: </p> <pre><code>Iterator it = headers.getAllHeaders(); while (it.hasNext()) { MimeHeader header = (MimeHeader) it.next(); String[] values = headers.getHeader(header.getName()); if (values.length == 1) { res.setHeader( header.getName(), header.getValue()); } else { StringBuffer concat = new StringBuffer(); int i = 0; while (i &lt; values.length) { if (i != 0) { concat.append(','); } concat.append(values[i++]); } res.setHeader(header.getName(), concat.toString()); } } </code></pre>

    1. CODid you post correct client side code? Which line throws an error (`SOAPMessage response = con.call(msg, endpoint);`)?

    2. COit is the correct client side code, although it looks like it originates from the server side....it happens at the point of: SOAPMessage response = con.call(msg, endpoint);

    3. COIf the error is thrown on that line it means that the server received the request, processed it and returned a response already. The error indicates that the data/message returned by the server is not of the expected format. Try to connect to the server via telnet and check the response - is it well formatted and does it contain all information you expect?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
