If you want to use org.apache.xerces.parsers.SAXParser, you should import it
as you did with org.xml.sax.XMLReader. Alternatively you can just call:
XMLReader parser = new org.apache.xerces.parsers.SAXParser ();
As for your second problem, make sure you remove the 'package sax;' line or
change it to reflect the new directory in which you placed your copy. (i.e.
'package practice;')

Subject: Problem with Xerces-1_2_1(Java)
Hi ,
I have downloaded the xerces-1_2_1 from apache site.I am reading the
Java-Xml Book from Oreilly.
After extracting the xerces files I have set the classpath to
<roo>/xerces.jar and <root>xercesSamples.jar.
Then I have created one folder called 'practice' inside 'Samples' i.e
(<root>/Xerces/Samples/practice).Now I am facing two problems.
1. I wrote SAXPerserDemo.java and saved it inside 'practice' as below:
import org.xml.sax.XMLReader;
public class SAXPerserDemo{
public void performDemo(String uri){
System.out.println("Parsing XML FIle :"+uri+"\n\n");
try{
XMLReader parser =
(XMLReader)Class.forName("org.apache.xerces.parsers.SAXParser").newInstance(
);
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String args[]){
if(args.length == 0){
System.out.println("Usage:java SAXPerserDemo [XML URI]");
System.exit(0);
}
String uri = args[0];
SAXPerserDemo perserDemo = new SAXPerserDemo();
perserDemo.performDemo(uri);
}
}
In oreilly it is given :
XMLReader parser = new SAXParser();
But this line does not compile in this version of Xerces.So I made the
changes as
XMLReader parser =
(XMLReader)Class.forName("org.apache.xerces.parsers.SAXParser").newInstance(
);
then it compiles successfully.
Now what should I do to get the line XMLReader parser = new SAXParser();
compiled successfully.
2. When I copiled the file SAX2Count.java from 'sax' to 'practice'
directory and made some changes and rename it as SAX2CountModified.java
then it compiled
successfully but when I gave the command java SAX2CountModified then it
gave me the exception
as:
G:\Xerces\Samples\practice>java SAX2CountModified
Exception in thread "main" java.lang.NoClassDefFoundError: SAX2CountModified

Waiting for your mail.
