   • Basic understanding of networking concepts, including protocols (HTTP, HTTPS) and network configurations relevant to server deployment.

10. Linux/Unix Command Line:

    • Familiarity with the Linux/Unix command line, as many server environments, including JBoss, are often deployed on Unix-like operating systems.

11. Security Concepts:

    • Basic knowledge of security concepts related to web applications and servers, including authentication, authorization, and secure communication.

12. Version Control Systems:

    • Experience with version control systems like Git for managing source code and collaborating with a development team.

13. Scripting Skills:

    • Basic scripting skills, such as Bash or PowerShell, for tasks related to server administration and automation.

14. Troubleshooting and Debugging:

    • Proficiency in troubleshooting and debugging Java applications and server-related issues.

15. Continuous Learning:

    • A mindset of continuous learning, as technologies and best practices in Java development and server administration evolve over time.
