When you build a Java application, the final packaged artifact is often an EAR (Enterprise Archive) file. In enterprise setups, deploying this EAR into a JBoss Application Server manually can be time-consuming and error-prone.

That’s why we use deployment scripts — to make the process reliable, repeatable, and faster.

In this post, we’ll break down a sample Bash deployment script for JBoss.

The Script

Here’s the complete script:

#!/bin/bash
set -euo pipefail
...
# (full script shown above)

Now let’s walk through it step by step.

Key Sections Explained

1. Safety and Logging

set -euo pipefail

• Stops execution if a command fails (-e), if an undefined variable is used (-u), or if a pipeline command fails (-o pipefail).
• This makes the script more robust.

- The error_exit Function

error_exit() {
    log "Error: $1"
    exit 1
}

🔹 Purpose

• Provides a centralized way to handle errors.
• Whenever something goes wrong, this function is called.

🔹 How it Works

• $1 is the first argument passed to the function (the error message).
