[jdom-interest] Using Project X SAX Parser with JDOM

[Kevin Swanson]

I'm trying to use Sun's Project X SAX parser in place of the default Xerces
parser. You are probably asking why. I've encountered a weird bug in my IDE
(VisualCafe 4.0), where using the Xerces parser blows up when i run it in
the debugger. So, I tried a bit of code like below where f is an
InputStream.

SAXBuilder builder = new SAXBuilder("com.sun.xml.parser.SAXParserImpl");
doc = builder.build(f);

When this runs, I get the following error:

org.jdom.JDOMException: SAX2 driver class com.sun.xml.parser.SAXParserImpl
loaded but cannot be instantiated (no empty public constructor?): SAX2
driver class com.sun.xml.parser.SAXParserImpl loaded but cannot be
instantiated (no empty public constructor?)

        at com.tallysys.jdom.JDOMTest.main(JDOMTest.java:82)

Is this because JDOM expects a SAX2 parser and Sun's is only SAX1? Is there
a way around this problem?

Thanks,
