Using java -jar

[Scott Harper]

If I want to run the command:

java -jar myApp.jar

does myApp.jar need to be in the $CLASSPATH, $PATH, or do I simply have to
give the fully specified path on the command line?


thanks

Your jar file needs to contain a valid manifest file that specifies the
Main-Class property. Apart from that, it's sufficient to give java the
fully qualified path.

As an aside, I always avoid using a CLASSPATH environment variable. At
best it is unnecessary and at worst it is dangerous.

Neither. You need to specify a valid relative or absolute path to the file,
just as if it were any other data file.
