WebLogic's High-Performance XML parser

Question

I understand that 6.1's high performance XML parser is the replacement of 6.0's
custom generated parser. Per the documentation, I need to set SAXParserFactory
to weblogic.xml.babel.jaxp.SAXParserFactoryImpl, but I couldn't find weblogic/xml/babel/jaxp/SAXParserFactoryImpl
in either weblogic.jar or xmlx.jar. There are bunch of weblogicx/xml/babel/* in
xmlx.jar.
When I call JAXP code, I got this error:
javax.xml.parsers.FactoryConfigurationError: Failed to find SAXParserFactory.
weblogic.xml.babel.jaxp.SAXParserFactoryImpl
javax.xml.parsers.FactoryConfigurationError: Failed to find SAXParserFactory.
weblogic.xml.babel.jaxp.SAXParserFactoryImpl
Am I missing something, or the 6.1 beta download forget to include the *.babel.jaxp.*
stuff?

Answer 1

Jim,
Please don't use System.setProperty() in any server code. This was intended
as an example only. I think the XMLReaderFactory is not specified in
JAXP1.1.
Thanks,
Chris

Jim,
Here is a code fragment to acess the parser:
System.setProperty("javax.xml.parsers.SAXParserFactory","weblogic.xml.babel.
jaxp.SAXParserFactoryImpl");
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
parser.parse("yourfile.xml",defaultHandler);

I just found out that XML Registry setting on SAXParserFactory does notapply to
XMLReaderFactory() and XMLReader:
XMLReader parser = XMLReaderFactory.createXMLReader();
I have to use SAXParserFactory to get High Performance Parser kicked in:
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
Is this the right behavior? Thanks for the help.

Chris,
Thanks for the reply. It still doesn't work. I think the problem is
that weblogic.jar
and xmlx.jar both does not have eihter
"weblogicx.xml.babel.jaxp.SAXParserFactoryImpl"
or "weblogic.xml.babel.jaxp.SAXParserFactoryImpl". So the current Beta
download
forgot to include the above classes. I might try download Beta again
to see if
any difference.

This is a mismatch between our beta and the final place that the
parser
will
live in the release, you should be able to get the parser by setting
the
SAXParserFactory to weblogicx.xml.babel.jaxp.SAXParserFactoryImpl (it
will
be weblogic.xml.babel.jaxp.SAXParserFactoryImpl in the final release).
A couple notes:
The parser only handles standalone documents, with no entityreferences
and
is optimized for small to midsize documents (IE soap and wsdl type
documents).
Pleas let me know if you can get it to work.
