How to convert a string to a SOAPMessage in Java?
This works for me:
SOAPMessage sm = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage(new MimeHeaders(), is);
Convert the String into an input stream, then read it into the SOAP message factory.
InputStream is = new ByteArrayInputStream(send.getBytes());
SOAPMessage request = MessageFactory.newInstance().createMessage(null, is);
You can read about how to do this here.
I've measured feeding SOAPMessage with SAXSource to be about 50% faster than internal SAAJ parsing implementation used in the accepted answer:
SOAPMessage message = messageFactory.createMessage();
message.getSOAPPart().setContent(new SAXSource(new InputSource(new StringReader(send))));
Here is the benchmark testing various XML parsing sources and factory caching impact:
