How to run a jar file in a linux commandline


How to set the classpath to the current directory and also run the jar file named load.jar present in the current directory by providing the argument as load=2 from a linux command line.

I did try to run the jar as follows but its executing classes from some other directory.

java -cp ./load.jar:$CLASSPATH load.Start load=2

The Best Answer is


Running a from class inside your JAR file load.jar is possible via

java -jar load.jar

When doing so, you have to define the application entry point. Usually this is done by providing a manifest file that contains the Main-Class tag. For documentation and examples have a look at this page. The argument load=2 can be supplied like in a normal Java applications:

java -jar load.jar load=2

Having also the current directory contained in the classpath, required to also make use of the Class-Path tag. See here for more information.

For example to execute from terminal (Ubuntu Linux) or even (Windows console) a java file called filex.jar use this command:

java -jar filex.jar

The file will execute in terminal.
