Hi
I have a query regarding SAX parser. my java class uses SAX
2.0.
It needs a driver. I downloaded xerces 1.4.3 to get the class
which implements XMLReader interface. This class
(org.xml.sax.helpers.ParserAdapter) acts as a parser driver.
correct me if I am wrong. After compiling i give
(java -D org.xml.sax.helpers.ParserAdapter MySAXApp roses.xml)
on the command line. The thing is in classpath I have given
both xerces 2.0.0 and xerces 1.4.3. I have to use 1.4.3 's
adapter classes. How will i use them. is there any other way
to have driver for sax2.0 I am pasting my java class below.
Thanks
Vijay
