Big5 encoding problem

[mikeliu1976]

regards:

I use Current Version (1.5) to parse the web location "http://www.yzu.edu.tw/"
and output to test2.txt.

"javac ToHtmlDemoBig5" is ok.
when 
"java ToHtmlDemoBig5"

monitor says:
unable to determine cannonical charset name for big5 - using ISO-8859-1

Do I miss something important? 
thank you
Followings is my code.
---------------------------------------------------------------------------
import org.htmlparser.Parser;
import org.htmlparser.util.NodeIterator;
import org.htmlparser.util.ParserException;
import java.io.*; 

public class ToHtmlDemoBig5
{
public static void main (String[] args) throws ParserException
{
// PrintWriter out= new PrintWriter(); 
try{ 

FileOutputStream htmlparserOutput = new FileOutputStream("test2.txt"); 
PrintWriter out=null;
out = new PrintWriter(htmlparserOutput); 
Parser parser = new Parser ("http://www.yzu.edu.tw/");
parser.setEncoding("Big5"); 
//StringBuffer html = new StringBuffer (4096);
for (NodeIterator i = parser.elements();i.hasMoreNodes();){
// out.print (list.elementAt(i).toHtml ()); 
// html.append 
out.print(i.nextNode().toHtml());}

// System.out.println (html);

out.close();
htmlparserOutput.close();
}
catch(IOException e)
{
}
// test2.close();

}
}

It seems java.nio.charset.Charset.forName ("big5") has failed.
Try using "Big5" (with the capitalization).

regards: 

I change my jdk edition from 1.4.0 to 1.4.2_08.
It is OK.
