Actually, Forte and netbeans are both free.  Forte and netbeans can
debug at runtime.  You can set break points and everything.

hi trenton,

if u have some fancy IDE like Visual Age/Visual Cafe' u can debug
applications at runtime...but sadly the vast majority of us cannot
afford such tools..so we print to the console...however my box is win98
and the console window does not scroll beyond 50 lines..so i wrote a
simple log file.. and i pipe the output to the file.....in a production
environment u can then parse this logfile for errors,excptions etc using
any regexp package or perl scripts..i have found it very useful..here is
the code

import java.io.*;

public class LogFile {

    /** Creates new LogFile */
    public LogFile() {}

    public static void log(String str) {

        try {
            File f = new File("C:/wclog.txt");

            f.createNewFile();

            RandomAccessFile out = new RandomAccessFile(f, "rw");

            out.seek(out.length());
            out.writeUTF("\n");
            out.writeUTF(str);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

import this file in ur servlet/JSP and use LogFile.log("<ur commenrts
etc>")....

hope this is useful..
