JSF

Hello guys, my first time here, and for requesting advice.

I am a JavaScript Developer MERN Stack with a focus on Frontend Development. I wanna go more to Backend Development.

Which Language has a Solid Ecosystem and not so many changes like JavaScript Frontend, quite Frankly that's freaking me out nowadays!

In my Location Germany Industries, Finance, Utilities, Insurances, Retails, and Healthcare dominate Java in the Backend. In my case Java is the logical choice BUT, XML, old codebase, JSP/JSF , boring and verbose syntax without Syntactic Sugar, test Battle, and so on make me crazy.

I have Java, Python, Golang, and Node.js/TypeScript as a choice, but because of a lack of Backend knowledge, I can't make a decision. Which Language and Ecosystem should I learn and master for a long time, my Goal is to work with a selected stack for 10+ years and I don't do Data Science only Software Engineering.

Thanks for reading and Advice! Important! !!! I see via Email somebody send me an Advice, but unfortunately i can't see/read your Advice here :( Users like: Jose Manuel Ortega or nullStack65....

Hello guys! I would ask for your advice. Our situation is like that there will be a project to revamp workflows and introduce new services like mobile apps, machine learning, and some online services that would use cloud storage. We use JSF, JavaScript, Ajax, Spring, Oracle 12c running on Linux (VM) and providing online services to internal users and the public. But, we are not technically savvy enough to evaluate what tools should be introduced. Personally, I am evaluating whether to take this opportunity to change our practice/PM approach from Prince to Scrum/Agile (It seemed that DevOps is popular) ... Since we adopt ISO 27001 and ISO 20000, security is a crucial factor that we consider. Would you please help to recommend a list of tools and explain the reasons why you recommend them? Thanks in advance~!

I need to modernize a Java web application that runs on JSF. I am used to building websites, so Bootstrap kinda feels like "home." But when it comes to applications, I feel Bootstrap is not the right way to go. Can someone explain to me what PrimeFaces is capable of in comparison with BS?
