Why web developers still widely use Java frameworks?

Question

Nowadays very different and easy to use frameworks as Django is developed by companies. But big development companies in my country still using Java frameworks as Wicket, JSP, Spring for backend web development.

Answer 1

The main reason is likely an old developers generation is in the top now. If they have the machine and services running for it you will always see some of it going. Banks still mainly run on Java and even Cobol cause it's a costly operation to switch to a newer technology. However nowadays you see that Cobol developers are rare and they are forced to switch. The same thing will happen to back-end java frameworks.

Couple reasons to move on:

1. accessibility, the learning curve for Java is quite big compared to javascript or PHP. HTML5 also has a far lower learning curve and is powerfull enough

2. webservers aren't main frames, Java runs fine starting it once and probably will run on any webserver a couple times but when all sessions a webserver has with it's clients would run in Java it wouldn't take it.

3. The client is required to install java, Oracle doesn't do that to access their website for the simple reason that HTML is much better at this task, since web browsers have native support for html.

Answer 2

SEO methods attract more traffic, not a specific language.
Tech leaders choose tools and frameworks for development. So, Java developers tend to choose this language for web development as well as for mobile and desktop development. And with frameworks the development process becomes more easier, cheaper and satisfying.

Answer 3

I can be wrong but maybe main reason is in java security?

Answer 4

It's been noted, that Java powered websites tend to attract more traffic, than other languages.
It could also be because those companies wouldn't like to refactor their codebase
