[lupercal hill]

Im running the following code. using jdk1.5.0_04. Do i need to add anything to use sax. I think i might need a package but i dont know.
I get a no class def found error.

The tutorial Im using is here, the code is below

http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/TOC.html

import java.io.*;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
import javax.xml.parsers.SAXParserFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
 
public class Echo extends DefaultHandler
{
    public static void main(String argv[])
 
   {
        if (argv.length != 1) {
            System.err.println("Usage: cmd filename");
            System.exit(1);
        }
        try {
            // Set up output stream
            out = new OutputStreamWriter(System.out, "UTF8");
 
        } catch (Throwable t) {
            t.printStackTrace();
        }
        System.exit(0);
    }
 
    static private Writer out;


 

}

I dont need to do anything to import SAX. The problems I had were due to me using argv instead of args.

public static void main(String argv[])

public static void main(String args[])

If your code looks exactly like the above, the problem was not in the fact that you used the name "argv" instead of "args". It's just a variable name, it does not cause a ClassNotFoundException.

You probably hadn't your classpath set up correctly.

Lupercal Hill,

I'm not really sure what you mean by this:

public static void main(String argv[])

public static void main(String args[])

I feel the name in the parameter should not matter, as long as you use the same name inside your method body. Of course you wouldn't want to use any of the keywords here.
