Open your favorite text editor with a new file and save it as ~/.local/bin/java-app with below content - the ensures that any arguments to the script is passed on to the java-app.jar file #!/bin/sh If you want to launch the program from your menu or the terminal - create a script and a launcher as follows.Īssuming it is in Downloads mv ~/Downloads/java-app.jar ~/.local/bin To run the application contained in the jar java -jar java-app.jar Or the complete environment sudo pacman -Syu jdk-openjdk

RUNNING JAVA JAR FILE WITH ARGUMENTS FULL
The jar requires at least JRE (Java Runtime Environment) - some requires the full JDK (Java Development Kit).

Main-Class: com/mycomp/myproj/dir1/MainClass1 We can add our java file to manifest file so that we no need to pass the class name to java command while running it from command line.Įxample with custom class in Manifest.mf file : Implementation-Vendor: Oracle Corporation Implementation-Title: Java Runtime Environment Specification-Title: Java Platform API Specification Here, is what a default manifest file looks likeīelow is from official java version jrt-fs.jar from java 11.
Although the default manifest file contains just two entries, but complex manifest files can have way more. Default manifest file is named as MANIFEST.MF and is present in the META-INF sub-directory of archive. Each JAR file have a manifest file by default. MANIFEST.MF file: Each JAR file contains a manifest file that describe the features of the archive. Java -cp myJavaJar.jar 2.MainClass2 /home/myhome/datasource.properties /home/myhome/input.txt Then : Just need to pass the complete fully classified name of the class. You can create your jar without Main-Class in its Manifest file. Solution: The solution for this issue is described below. (In the above command, '/home/myhome/datasource.properties' and '/home/myhome/input.txt' are the command line arguments). Jar cfe myJavaJar.jar 2.MainClass2 com/mycomp/myproj/dir2/MainClass2.class /home/myhome/datasource.properties /home/myhome/input.txtĬom/mycomp/myproj/dir2/MainClass2.class : no such file or directory But is there any way by which I can specify some argument on command line to run whichever class I wish to run? I know that I can specify one class as main in my Manifest file. It has directory structure for the main classes as follows:
I am trying to run it from command-line on Linux box. I want to be able to run each one of those as per the need. I have a JAR with 4 classes, each one has Main method.
RUNNING JAVA JAR FILE WITH ARGUMENTS HOW TO
How to run a class from Jar which is not the Main-Class in manifest file: Here, flag cp is to set the jar in the java class-path.
