When I use batchfile.bat >> logfile.txt command in the Windows commandline, it correctly outputs the normal output into the text file, but the Java exceptions get output to the console. Can I make it so that exceptions are written to log file as well?
Java exceptions are printed on the standard error stream.
To pipe the standard error stream (file descriptor 2) into a file you can do:
batchfile.bat 2>> errorlog.txt
To pipe both standard error and standard out into the same file:
batchfile.bat >> logfile.txt 2>&1
You can do the same on Unix and Windows
