SAXParseException: The processing instruction must begin with the name of the target

[Sandip Satpathy]

Hi,   can some one help me ?   My SOAP service is sending me following respose   <? xml version='1.0' ?> <soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/"> <soap-env:Header> <gpp-mm7:TransactionID xmlns:gpp-mm7="http://localhost/soap/REL-5-MM7-1-0" soap-env:mustUnderstand="1"> 123 </gpp-mm7:TransactionID> </soap-env:Header> <soap-env:Body> <gpp-mm7:SubmitRes xmlns:gpp-mm7="http://localhost/soap/REL-5-MM7-1-0"> <MM7Version> 1.0</MM7Version> <Status> <StatusCode> 1000</StatusCode> <StatusText> Ok</StatusText> <Detail></Detail> </Status> <MessageID> b4ec400004VRyW.kWRqV4kc3oPPVzak0N</MessageID> </gpp-mm7:SubmitRes> </soap-env:Body> </soap-env:Envelope> But my soap client is not able parse the response envelope . I am getting following exception: org.xml.sax.SAXParseException: The processing instruction must begin with the name of the target.         at org.apache.xerces.framework.XMLParser.reportError(XMLParser.java:1056)         at org.apache.xerces.framework.XMLDocumentScanner.reportFatalXMLError(XMLDocumentScanner.java:626)         at org.apache.xerces.framework.XMLDocumentScanner.abortMarkup(XMLDocumentScanner.java:680)         at org.apache.xerces.framework.XMLDocumentScanner$XMLDeclDispatcher.dispatch(XMLDocumentScanner.java:748)         at org.apache.xerces.framework.XMLDocumentScanner.parseSome(XMLDocumentScanner.java:381)         at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:948)         at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.java:123)         at MM7Client.main(MM7Client.java:54) how ever if I will remove the xml prologue i.e. "<? xml version='1.0' ?>" then it is able to parse.   can any one pls suggest me what could be the reason ?   We are using 1. Apache SOAP Version 2.2 2. Xerces Java Parser 1.2.3     Code that I am using for parsing is the SOAP response is as follows:            try  {             DocumentBuilder xdb = XMLParserUtils.getXMLDocBuilder ();             Document doc = xdb.parse (new InputSource(new StringReader(xmlmsg)));             if (doc == null) {                 System.err.println ("Failed to parse XML");                 return;             }             Envelope msgEnv = Envelope.unmarshall(doc.getDocumentElement());          } catch (Exception e){             e.printStackTrace () ;          }     Regards,   - Sandip
