I decided to try java EE and ran into a typical problem “a lot of information”.

Now more specifically. I found such a wonderful site in which there is a description of how, thanks to spring, you can display "hello world".

Approaching the essence - knowing java SE (omitting any knowledge in android, as I understand it, they will not be useful) how to overcome this gap between java SE and java EE. After all, the appearance of configs, maven, a variety of springs (protection, web, MVS, etc.) are introduced into a stupor.

Specifically, in the above site, with "hello world" I do not understand at what point xml is connected (taking into account the java EE syntax) and the usual model (class) from java SE.

Now briefly: I do not understand the moment in which these technologies are intertwined, the site simply has xml as a given, and I do not understand what it is sticking to. Push in the right direction?

Abstract explanations like "there is a bean, it goes from the page sent by the server on the unicorn to the 3/4 station and is processed there" will not be informative. I ask the specifics.

Please correct the question so that it describes the specific problem with sufficient detail to determine the appropriate answer. Do not ask a few questions at once. See “How to ask a good question?” For clarification. If the question can be reformulated according to the rules set out in the certificate , edit it .

  • What is there is not clear? There is a spring framework, and this is its xml. He reads it and on the basis of it creates all these bins. Establishes connections between them, shoving each other. Using spring, you create a program under the spring framework. Well, what is the relationship between SE and EE? Yes, the dog knows it. SE is the base for everything written in java? EE add-on for its own purposes, for EE. - Sergey
