Hello! I'm making some program (not in java - in PHP if it matters but its really irrelevant). I need to compile some java files with javac.exe (and later run them) To compile it I first copy all necessary files into a folder called "temp" and then compile it. Example batch code: cd temp D:\Programs\Java\bin\javac.exe Tester.java > compile_log.txt java Tester > log.txt When the java code is correct the program creates a file named "compile_log.txt" which is empty, and a file called "log.txt" with all the output from the java program. (Which is perfect). Now, when there are java compilation errors, I've expected compile_log.txt to contain all the errors, but its still empty. How can I output the compilation errors into a file using batch?

Have you tried D:\Programs\Java\bin\javac.exe Tester.java 2> compile_log.txt

Wow! Thank you for the quick (and correct!) reply! It works like a charm! But I would really like to know what the "2" stands for. The second "section"? second "echo statement"? Thanks again, Daniel

Standard error.
