I am facing a strange issue. My code runs just fine from Netbeans or cmd with
> java -jar MP2.jar
but when I try to run it from the .bat
"%JAVA_HOME%"\bin\java -jar .. \dist\MP2.jar > test_mp2_out.txt
I get just error in my text file
DataIn\nrmavg.txt (The System cannot find the path specified)
or a null pointer exception at the line I have new
I can provide more code if needed, but I think this may be a windows problem.

This is a guess, but the file you're trying to read is probably in some folder relative to your working directory, and the working directory is different when you run the code from your batch file.
I agree. Here's the link:
