Installing GlassFish on Ubuntu 22.04

GlassFish is an open-source application server that implements the Java Enterprise Edition (Java EE) specifications. It provides a runtime environment for developing and deploying enterprise Java applications. This powerful application server offers features such as web services, advanced management capabilities, and support for clustering and high availability.

Step 1: Update System Packages

sudo apt update
sudo apt upgrade -y

Step 2: Install Java Development Kit (JDK)

Before installing GlassFish, you need to have the Java Development Kit (JDK) installed on your system. Run the following commands to install OpenJDK 11:

sudo apt install openjdk-11-jdk

Step 3: Download GlassFish

Visit the official GlassFish download page (https://glassfish.java.net/) and download the latest stable version of GlassFish.

Alternatively, you can use the following command to download GlassFish directly from the terminal:

wget https://download.oracle.com/glassfish/5.1.0/release/glassfish-5.1.0.zip

Step 4: Unzip GlassFish

Once the download is complete, navigate to the directory where the zip file is located and unzip it:

unzip glassfish-5.1.0.zip

Step 5: Set Up Environmental Variables

Open the '.bashrc' file using a text editor:

nano ~/.bashrc

Add the following lines at the end of the file:

export GLASSFISH_HOME=/path/to/glassfish
export PATH=$PATH:$GLASSFISH_HOME/bin

Replace '/path/to/glassfish' with the actual path to the GlassFish installation directory.

Save the file and exit the text editor. To apply the environmental variable changes, run the following command:

source ~/.bashrc

Step 6: Start GlassFish

To start the GlassFish server, use the following command:

asadmin start-domain

Step 7: Access GlassFish Admin Console

Open a web browser and enter 'http://localhost:4848' in the address bar. This will bring up the GlassFish Admin Console.

At this point, GlassFish is successfully installed on your Ubuntu 22.04 system. You can now deploy and manage Java EE applications using this powerful application server.
