java.lang.InstantiationException

Hello,

since I wanted the simplest SAX parser
for parsing non well formed XML,

I wrote a tokenizer & a parser class that throws the basic events (start
element, characters, ...aso),
but when instantiating the class,
I get the following error.

java.lang.InstantiationException 	at
org.xml.sax.helpers.XMLReaderFactory.createXMLReader

The class is abstract and has an empty constructor.

What am I doing wrong?

regards,

Bram
