Java Programming

Hi,

I am new to java..

I am trying to calculate MD5 checksum for an xml input. Below is the code i am using

package Md5Package;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class MD5Checksum
{  
    public static void main (String[] args)
    {
        String md5val = "";
        MessageDigest algorithm = null;
        try
        {
            algorithm = MessageDigest.getInstance("MD5");
        }
        catch (NoSuchAlgorithmException nsae)
        {
            System.out.println("Cannot find digest algorithm");
            System.exit(1);
        }
        
        for (String arg : args)
        {
        	md5val = getHexString( algorithm,arg);
        
         }

    }
    
    public static String getHexString( MessageDigest algorithm,String arg){
        byte[] defaultBytes = arg.getBytes();
        algorithm.reset();
        algorithm.update(defaultBytes);
        byte messageDigest[] = algorithm.digest();
        StringBuffer hexString = new StringBuffer();

        for (int i = 0; i < messageDigest.length; i++)
        {
            String hex = Integer.toHexString(0xFF & messageDigest);

if (hex.length() == 1)

{

hexString.append('0');

}

hexString.append(hex);

}

System.out.println("md5val");

return(hexString.toString());

}

}





It actually calculates the MD5 for a string. But i need it for an xml type input. Any suggestions on this? I am new to java sorry if its a basic question. Appreciate your suggestions. Thanks
