This message may be a bit verbose, but please bear with me as I try to
establish background.
I have been working on un-marshalling a FastInfoset compressed binary XML
document to a XmlBean.
The XmlOptions class lets me specify an org.xml.sax.XMLReader, so I do this via
setLoadUseXMLReader(). I am looking at
com.sun.xml.fastinfoset.sax.SAXDocumentParser, as it implements XmlReader.
I FastInfoset compressed a simple XML instance document. As background, my
XmlBean class is DatabaseConnectionDocument.java and my XML instance is
databaseConnection.xml. Now the task is to instantiate a SAXDocumentParser,
set the XmlReader in XmlOptions, and call
DatabaseConnectionDocument.Factory.parse().
My problem is I am getting a RuntimeException related to setting the Namespaces
Feature in FastInfoset. The full text of the exception is below.
I looked into the com.sun.xml.fastinfoset.sax.SAXDocumentParser.java
FastInfoset source code. The setFeature(String name, boolean value) method is
coded to throw a SAXNotRecognizedException if called as in:
setFeature("http://xml.org/sax/features/namespaces";, true);
It looks like this is what is happening at Locale.java line 3320 (I have not
looked at the Local.java source code).
So I modified SAXDocumentParser.java to disable the throwing of
SAXNotRecognizedException. I re-compiled FastInfoset.jar, then successfully
ran my test code. Thus marshalling a FastInfoset compressed XML document to a
XmlBean. My test code also appears below.
The bottom line of this (and my question) is:
Am I not configuring something in XmlBeans properly or is there perhaps an
issue with FastInfoset? Perhaps the FastInfoset code (SAXDocumentParser.java)
ought to no-op the setFeature("http://xml.org/sax/features/namespaces";, true)
call rather than throwing the SAXNotRecognizedException.
Thanks,
Fred Burkley
