How to learn Java EE?

Question

Java

Hello!
Question for those who work with Java EE.
I will describe my situation: I
have basic knowledge of Core (I continue to study more deeply, I read books about concurrency, generics, and so on). I have experience in developing one project in Yii2 (php-framework). For about a year I worked part-time as an HTML/CSS coder, so I had a chance to work with JS a little (without frameworks, only JS and jQuery). Wrote several modules for an Android application. I have basic knowledge of Linux (for the last 2 years, my main operating system, I set up and configured all kinds of Apache and nginx both on my own and on the project's combat server). I also had some experience in C # (I wrote in Xamarin, something like a cross-platform framework for mobile OSes). Well, the rest of the little things. I have not yet worked for my uncle (the second year, they do not take it).
There is a goal - to train yourself in such a way that by the third year they would take the position of junior without hesitation and so that there would be less to the middle. If in Russian - it is necessary for the remaining year to do something as useful as possible.
Question - tell me in what order to study? Can you tell me some classic test projects (something like a calculator for beginners to code)? I fully understand that I won’t make a big mistake in my choice, and it will be useful one way or another, but I just want to use my time more efficiently.
The most accurate wording of the question is you are a cool senior, imagine that you are me with my experience that I described above. Looking through the lens of your experience, how would you study EE?

Answer 1

Start by learning JSP + Tomcat. Write a simple CRUD application using servlets and JDBC. Then move on to JPA. Next you can try Spring

Answer 2

Take Spring, explore spring.io/guides and write a toaster clone.
This is junior level.

Answer 3

My advice is: Java SE => JDBC => Servlets + JSP => JPA, Hibernate (Surface) => Spring (Surface) => Small Web Project => And then learn Hibernate and Spring in more depth.
Well Tomcat by itself. Java EE for me is more complicated and more sophisticated than Spring.
