-------------------------------------
Summary: Inconsistent serialization of SOAPEnvelope
Key: AXIOM-430
URL: https://issues.apache.org/jira/browse/AXIOM-430
Project: Axiom
Issue Type: Bug
Components: DOOM, LLOM
Affects Versions: 1.2.13
Reporter: Andreas Veithen
Priority: Minor
The SOAPEnvelopeImpl#internalSerialize method contains code that skips the
serialization of the SOAP header if it is empty. Presumably this code is there
because SOAPFactory#getDefaultEnvelope() always creates a SOAP header, but one
doesn't want that header to appear in the output if there are no header blocks.
However, this only works when the SOAPEnvelope is serialized to an
XMLStreamWriter, OutputStream or Writer. The header is still present in the
sequence of events produced by getXMLStreamReader or getSAXSource. This can be
shown using the following piece of code:
SOAPFactory factory = OMAbstractFactory.getSOAP11Factory();
SOAPEnvelope envelope = factory.getDefaultEnvelope();
factory.createOMElement(new QName("urn:test", "test", "p"),
envelope.getBody());
envelope.serialize(System.out);
System.out.println();
TransformerFactory.newInstance().newTransformer().transform(envelope.getSAXSource(true),
new StreamResult(System.out));
The output is:
<?xml version='1.0' encoding='utf-8'?><soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";><soapenv:Body><p:test
xmlns:p="urn:test"/></soapenv:Body></soapenv:Envelope>
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";><soapenv:Header/><soapenv:Body><p:test
xmlns:p="urn:test"/></soapenv:Body></soapenv:Envelope>
In addition to that, SOAPEnvelopeImpl#internalSerialize also skips
serialization of whitespace and comments.
