Java output console error message to file?

Question

I have a simple piece of code that outputs console text to a text file in Java:

PrintStream out = new PrintStream(new FileOutputStream("test2_output.txt"));
System.setOut(out);

However I require this text file to contain the error messages that is produced in the console but they are not included.

How do I do this?

Add:

System.setErr(out);

at the end.

Thanks very much. Did the job perfectly. I can't believe I couldn't find this statement anywhere on Google.

There is also a System.setErr() call to redirect stderr.

You're currently redirecting the standard output stream to a file. To redirect the standard error stream use

System.setErr(out);

System.setErr()^javadoc

Try:

PrintStream pst = new PrintStream("Text.txt");  
System.setOut(pst);
System.setErr(pst);
System.out.println("Hello, Finally I've printed output to file..");
