    Default Clearing up the air on javaEE

    Hi guys please I want someone to throw light on a somewhat "stupid question" for me. Am a budding java enthusiast with so much interest and passion for the language. I have resorted back to my first love and as a result, dedicated the latter part of my past year and the whole of this year to get to know at least at an elementary level the need to know of most if not all of the java technologies before I finally specialize in an area I find intriguing and challenging.

    I am weeks away from getting my OCJP in java SE7 but I noticed how the exam curriculum never even touched on the network infrastructure of java. So it got me thinking in the following direction;

    1. Just how much of core java knowledge is prerequisite or enough to step in to the real world( competitive industry) and be able to offer something without seeming half baked and incompetent.

    2. My eventual target is to be an java enterprise savant. The only internet knowledge I have is a bit of html and CSS which dates back to almost 7 years of real life working experience with either of them. Do i need to brush up on those skills and which
    other do I have to acquire to arm my self with before I take upon javaEE.

    3. Is it possible to design a website from scratch solely upon knowledge of java and does java provide tools that reduce designing web
    UI and styles to a drag and drop event.

    Finally, this is more like a request. I won't mid mentor-ship from any of you "java gurus" out there. my email address is ayoolagunju_muna@yahoo.com

    Because networking (like AWT/Swing, NIO, RMI, JDBC, etc...) is not part of SCJP/OCJP. The APIs I have mentioned are "advanced" APIs. While these exams mainly cover the "core" language (up to threading). If you have a very good knowledge of the core language you can virtually understand and use all (many, if not all) other APIs.

    In the real "industry" world it's surely necessary to have a very good knowledge of the core Java language plus ...
    - generics & collections
    - threading, concurrency
    - basic I/O, at least the entire java.io package (SCJP/OCJP only cover a small part of it)
    - regular expressions (sometimes are very useful)

    Then depending on the work context, you can need to know JDBC, AWT/Swing and/or other more advanced technologies/frameworks (JPA, Servlets/JSPs, etc...). And it's possible that you need to acquire a higher certification like the SCWCD.

    About networking, it depends on what precisely. In real industry world it's very rare that you need to use directly, for example, Socket/ServerSocket/DatagramSocket, unless you are asked to develop an implementation of an existing or a new applicative protocol. Which is certainly not a common task.

    About the JavaEE, the basic part at "presentation" level is composed by Servlet/JSP. And this is the main topic of SCWCD (now "Oracle Certified Professional, Java EE 5 (or 6) Web Component Developer").

    Many people can tell you that there are better technologies, like JSF, Spring, Struts, etc... It's true, these are more modern and widely used. But a minimal knowledge about Servlet/JSP is however a good "base".

    If you mean Java at "server side", no, the core Java language and Java SE framework are not sufficient. You need to know at least Servlet/JSP.
