System.out redirect

Anyone know of a way to redirect the output that the java engine creates to a text file? For example, if your program crashes due to a null pointer, the dos-console window prints out a list of like 15 lines or so with the error and where it occurred. Well, my console window's buffer is not always large enough for me to see what the last line of code that was executed.  Id like to somehow send this to a text file for reading.  Thanks!

use System.setOut and System.setErr passing a PrintStream opened on a FileOutputStream

Hai epastoor,


   It is very simple.  In order to redirect your console messages to a file,

you need to the following

for eg.,

java MyClass > console.log


after your program completion, you can open the console.log to see the outputs (System.out.println's)


All the best

Depends on which OS your running, and which version of Java.

The following will redirect all exception stack trace to a file named "errors.log":

try {
  System.setErr(new PrintStream(new FileOutputStream("errors.log", true)));
} catch (FileNotFoundException fileNotFoundException) {}

u can also use the following

javac -Djavac.pipe.output=true myfile.java > errors.txt
where myfile.java is your class file for compilation

cheers
