[shantimudigonda]

Hi All,

I am new to Java, I have written a program where i am getting the error

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0

here is the code.

import java.net.URL;
import java.io.*;
import org.w3c.tidy.Tidy;

public class TestHTML2XML {
private String url;
private String outFileName;
private String errOutFileName;

public TestHTML2XML(String url, String outFileName, String
errOutFileName) {
this.url = url;
this.outFileName = outFileName;
this.errOutFileName = errOutFileName;
}

public void convert() {
URL u;
BufferedInputStream in;
FileOutputStream out;

Tidy tidy = new Tidy();

//Tell Tidy to convert HTML to XML
tidy.setXmlOut(true);

try {
//Set file for error messages
tidy.setErrout(new PrintWriter(new FileWriter(errOutFileName), true));
u = new URL(url);

//Create input and output streams
in = new BufferedInputStream(u.openStream());
out = new FileOutputStream(outFileName);

//Convert files
tidy.parse(in, out);

//Clean up
in.close();
out.close();

} catch (IOException e) {
System.out.println(this.toString() + e.toString());
}
}

public static void main(String[] args) {
/*
* Parameters are:
* URL of HTML file
* Filename of output file
* Filename of error file
*/
System.out.println("url" + args[0]);
System.out.println("abc.xml" + args[1]);
System.out.println("123.xml" + args[2]);
TestHTML2XML t = new TestHTML2XML(args[0], args[1], args[2]);
t.convert();
}
}


Please help me out where i am doing wrong.

thanks in advance.

My guess: you're not passing any parameters to your main( ... ) method.

kind regards,

Jos

ps. the exception also tells you exactly where the error happened; look there.
