//Create a file object
File file = new File("c:\\temp\\log.txt");
//Create a FileWriter for easy output
try {
FileWriter fw = new FileWriter(File);
} catch(Exception e) {
System.out.println("Problem opening log file");
System.out.println(e);
}
//Any time you have an error message, do this
try {
fw.write("This is an error message!");
} catch(Exception e) {
System.out.println("Problem writing to log file");
System.out.println(e);
}
If you have trouble with security messages, you need to either sign the app
with a Verisign or Thawte ID or modify your java.policy to allow writing of
the file(s). Add this line to java.policy for the program above:
permission java.io.FilePermission "c:\\temp\\log.txt", "write";
Good luck,
Brian

Subject: Logging in Java
Hi all:
I have created a front-end user interface in Swing which communicates with
the middleware server.
Till now I was using "System.out.println()" statement for debugging but
since we have to ship the product, I have to remove all the print statements
and instead log all the messages in a log file.
Can u guys give me a headstart as to what I should do ??? maybe some link or
piece of code which will help me get started.
Cheers
Harry
