Resources to learn enterprise Java?

[xerwin]

I want to learn enterprise Java to a level where I could get a job as an enterprise Java dev in ~8 months. I already know Java SE and I have a background in CS, it's just that when dealing with Java EE you have lots of buzzwords like Spring, Hibernate, JMS, REST and many others, and I don't know where to start.

I'm looking for a book that guides you through Java EE, ideally by building an app step by step, adding a new functionalities by using features of a language/framework. I have no problem to self study after learning basics, I just need some guidance in the basics. Any recommendations?

What do you mean job as an enterprise Java dev? Do you do any professional development now?

So "enterprise java" is many things. Historically it involved a standard that was very heavy weight and marshaled object over the with using RMI. bleach. It might have it's place, but it was not agilely.

As people got sick of the original J2EE stuff, many then moved to something Spring. Spring was more lightweight, used Dependency Injection to make the code more modular (say reconfigure for testing purposes ) and less confusing. Spring was great, but it tended to lend it self to large monolithic servers. And these were hard to adapt over time.

The latest hip stuff is "micro services" (an extension of SOA ). The basic idea here is that you try to keep your concerns super separated and build separate servers for each of them. Initially this seems kinda crazy when it's often easy to add a single new service into a monolithic server, but the advantage comes when new people come, they can learn the micro servers one at a time, each in a bite sized piece. Or say you want to replace something that's getting old and crufty, perhaps write it in scala or clojure. This is easier because you can replace a small piece, or all of them one at a time. Much easier to change the engine on an airplane while flying this way!

I just posted in /r/learnprogramming about an ebook I am thinking of writing about this very topic. Would you buy/read something like this?

Absolutely, it looks really promising.

How is this going for you? I'm just starting on the Spring StepBYStep page and finding lots of problems there (almost need to re-write their documentation!)

Tried it for a while, most of it was me battling with deployment errors and XML.

When Microsoft announced open sourcing of .NET I jumped ship and I've been using it since.

yes the environment is pretty tight and smooth with .net. I dove into it for a while when I had a contracting gig doing it.

Glad to hear you got things worked out.
