executing java -jar via classpath vs in the jar file dir

Question

After having used NetBeans to create a Java program call it Addition and then having successfully cleaned and built an Executable Jar File in a folder c:\\Users\\Ben\\Doc\\NetBe

Answer 1

because java doesn't look in classpath to launch jar file for this command it needs file as input

so if you set the directory where your jar file is placed and try to execute java -jar command and expect it to pick up jar from that directory because it is in classpath it is not valid

you can give full path to jar like from any directory

java -jar c:\Users\Ben\Doc\NetBeansProjects\Addition\dist\Addition.jar

Answer 2

The -classpath argument is ignored when you use the -jar option. See the documentation.
