Autostart Glassfish on startup in Ubuntu

To make the Glassfish Server auto start with startup, we need to setting up an init script, which helps us to manage all Glassfish Server startup events easily. And also make Glassfish start up automatically whenever Ubuntu is rebooting.

This script file is glassfish to be created at /etc/init.d/. For managing all Glassfish Server startup events, it ships with the asadmin tool. Use this tool in the startup script as follows,

  1. Create or edit glassfish file sudo nano /etc/init.d/glassfish
  2. Paste the following lines in the file #!/bin/sh #to prevent some possible problems export AS_JAVA=/usr/lib/jvm/jdk1.8.0 GLASSFISHPATH=/home/glassfish/bin case “$1” in start) echo “starting glassfish from $GLASSFISHPATH” sudo -u glassfish $GLASSFISHPATH/asadmin start-domain domain1 ;; restart) $0 stop $0 start ;; stop) echo “stopping glassfish from $GLASSFISHPATH” sudo -u glassfish $GLASSFISHPATH/asadmin stop-domain domain1 ;; *) echo $”usage: $0 {start|stop|restart}” exit 3 ;; esac :

Now, glassfish startup script is created. We need to add this file in startup to make Glassfish Server autostart during Ubuntu startup. Follow these steps,

  1. Make the startup script file executable sudo chmod a+x /etc/init.d/glassfish
  2. Add this file to Ubuntu startup boot sudo update-rc.d glassfish defaults

That’s it. Now, restart Ubuntu and check if it really autostart the Glassfish Server.

You can also manage Glassfish Server startup events as follows,

  • Start the server /etc/init.d/glassfish start
  • Stop the server /etc/init.d/glassfish stop
  • Restart the server /etc/init.d/glassfish restart  

How to execute a .jar file from the terminal

To execute .jar file, java command should be used as below:

java -jar {path_of_the_file}/{file_name}.jar

And to execute above command, Java package must be installed on Ubuntu PC. To check if java package is already installed, execute below command in a terminal:

java -version 

It should display current version of Java package installed.

If it¬†displays “The program java can be found in the following packages”, It means Java hasn’t been installed yet. Execute below command in a terminal to install java package,

sudo apt-get install default-jre

This will install the Java Runtime Environment (JRE) only not Java Development Kit (JDK). If Java Development Kit (JDK) is needed, which is usually needed to compile Java applications, execute the following command in terminal:

sudo apt-get install default-jdk

That is everything to install Java. Now run first command to execute .jar file.
