The MessageBinding implementation throws a NULL Pointer exception if the root
element of the XMLStreamReader i/o message does NOT contain a namespace.

Key: XFIRE-867
URL: http://jira.codehaus.org/browse/XFIRE-867
Project: XFire
Issue Type: Bug
Components: Core
Affects Versions: 1.2.3
Reporter: Scott Seixas
Assigned To: Dan Diephouse
I am developing a solution using XFire that uses MessageBinding to transport
the entire XML input from the XFire client to my defined service as an
XMLStreamReader object. However, the OutMessageSender handler attempts to
serialize the XMLStreamReader object type to the XMLStreamWriter object via the
copy method in org.codehaus.xfire.util.STAXUtils.
During the STAXUtils copy, the writeStartElement method is invoked and if the
root element of the XMLStreamReader object does not contain a namespace then a
NULL Pointer exception is thrown because of the following two lines of code:
//STAXUtils.writeStatElement
//line 168
String uri = reader.getNamespaceURI();
//line 175
String boundPrefix = writer.getPrefix( uri );
When copying the root start element of the XMLStreamReader object, if the
namespace is empty or not defined then the uri string above is NULL, and
writer.getPrefix( NULL ) throws a Null Pointer exception.
I resolved this problem locally by modifying line 175 to the following:
// My fix - line 175
String boundPrefix = writer.getPrefix( uri != null ? uri : "" );
This prevents the NULL value from being passed as the input of writer.getPrefix.
In general it seems reasonable to require that the root element of the
XMLStreamReader object have a namespace, but in the case of MessageBinding the
XFire framework should NOT fail because the XML input/output does not have a
proper namespace. In this case it should not concern itself with the structure
of the XML i/o.
Please fix so that I can implement MessageBinding with XML i/o that does not
contain namespaces.
