Converting a SOAP file/string to message - Help for a $

[James Bukowska]

I have a SOAP message I coding by hand to mimic the response a server should send me if I sent a SOAP message and got a response back (since I can't atm get a response I just added what I thought I would get back to a .xml file and read it in)

All seemed to work fine until I wanted to get a value out of the SOAP message...

This is my message dumped into a file:

<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xml:space="preserve" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:method="http://alibris.com/webservices">
<SOAP-ENV:Body>

<method :-P	 utOrderResult xmlns="">
<sqlresultstream:SqlXml xsi:type="sqlsoaptypes:SqlXml">

 xsi:type="sqlsoaptypes:SqlResultCode">0</sqlresultstream:SqlResultCode>
</method :-P	 utOrderResult>
</method :-P	 utOrderResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Using the following:

  MessageFactory mf     = MessageFactory.newInstance();
            message   = mf.createMessage();
            SOAPPart soapPart = message.getSOAPPart();
 
FileInputStream is = new FileInputStream(file);

            // Set contents of message 
            soapPart.setContent(new StreamSource(is));

I managed to get the message and use message.writeTo(System.out) to print out what I actually expected to see:

<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xml:space="preserve" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"

So there I thought I had solved the conversion of a) file input to soap message and what follows, b) string conversion to soap message...

Alas, it was not to be... The next thing I wanted to do was to try and retrieve the success_or_failure value and use it for something, to do that I should need the SOAPBody so away I went again, only to be granted sight of the following exception: com.sun.xml.messaging.saaj.SOAPExceptionImpl: Unable to create envelope from given source:

Since the message printed okay using message.writeTo(System.out) I was somewhat mullified...

try
{
SOAPBody tmp = responseMessage.getSOAPBody();
}
catch(SOAPException se)
{
  se.printStackTrace();
  System.out.println("\nException getting soap body... e: [" + e + "]");
}

Any ideas greatly appreciated!

I have the suspicion that writeTo() only outputs the stream while getSOAPBody() actually initiates the stream parse. Your best bet is to start with a simple working example (like the one in this topic - it works with the Apache SAAJ) and convert it to using a FileInputStream. If that works replace the SOAP message in the file with your SOAP message. If that fails to parse, gut the contents of the envelope - once it starts to work build the envelope contents up again until it doesn't work. In other words, if you can get a simple SOAP message to work with a FileInputStream then there must be something peculiar in your SOAP message.
