-------------------------------------
Assignee: Benson Margulies
> org.apache.cxf.interceptor.StaxOutInterceptor uses StAX API incorrectly
> -----------------------------------------------------------------------
>
> Key: CXF-1622
> URL: https://issues.apache.org/jira/browse/CXF-1622
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.1
> Reporter: Pawel Lipka
> Assignee: Benson Margulies
>
> Method StaxOutInterceptor.handleMessage(Message msg) calls
> javax.xml.stream.XMLStreamWriter.writeStartDocument(String) assuming that the
> string arg denotes the xml encoding while the StAX javadoc says it denotes
> the xml version. There's another variant that has two inputs
> javax.xml.stream.XMLStreamWriter.writeStartDocument(String encoding, String
> version) that should be used instead.
> The snippet below highlights the erroneous api call:
> {code}
> public void handleMessage(Message message) {
> OutputStream os = message.getContent(OutputStream.class);
> XMLStreamWriter writer = message.getContent(XMLStreamWriter.class);
> if (os == null || writer != null) {
> return;
> }
> // assert os != null;
> // TODO: where does encoding constant go?
> String encoding = getEncoding(message);
>
> try {
> writer = getXMLOutputFactory(message).createXMLStreamWriter(os,
> encoding);
> if
> (Boolean.TRUE.equals(message.getContextualProperty(FORCE_START_DOCUMENT))) {
> writer.writeStartDocument(encoding);
> /*<=====================================================================THIS
> IS THE ERRONEOUS API CALL*/
> }
> } catch (XMLStreamException e) {
> throw new Fault(new
> org.apache.cxf.common.i18n.Message("STREAM_CREATE_EXC", BUNDLE), e);
> }
> message.setContent(XMLStreamWriter.class, writer);
> // Add a final interceptor to write end elements
> message.getInterceptorChain().add(ending);
> }
> {code}
