Posting or streaming XML to WebService

[Chris Gastin]

Can some one point me to a simple tutorial which allows you to post or stream an xml to a URL. Does this make any sense? Is this even possible with web services?

[Lasse Koskela]

If you Google for "sending HTTP POST with Java", you'll find plenty of sample code like this. You just need to replace the 'data' variable in that example with the raw XML.

Hi,

I need to post a xml document to a web service using SOAP and not URLConnection class. Could someone please help me with this.

Thanks & Regards,

Not sure if this is what u need exactly, but u can do something like this using SAAJ and DOM apis:

DocumentBuilderFactory dbFactory = 
  DocumentBuilderFactory.newInstance();
dbFactory.setNamespaceAware(true);
DocumentBuilder builder = dbFactory.newDocumentBuilder();
Document document =
  builder.parse("file:///order/soap.xml");
DOMSource domSource = new DOMSource(document); 
 
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage(); 
SOAPPart soapPart = message.getSOAPPart(); 
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPBody body = envelope.getBody(); 
 
SOAPPart soapPart = message.getSOAPPart();
soapPart.setContent(domSource); 
 
java.net.URL endpoint = new URL(
  "http://www.my-orl.org");
SOAPMessage response = connection.call(message, endpoint);
connection.close();

Hi ashutosh,

Thanks for the code. Which SOAP implementation did u use? I mean which vendor's api? And also do we need a proxy server on the application server box.

Well, I used Axis jars, but saaj and dom apis are standard and will work irrespective of which implementation u choose. I don't think there is any need of proxy server on the application server.
