How learning J2EE?

i've been learning java for one year.now i want to learn J2EE,but as a student,i have no
chance to "do Projec"t,it is impossible to "do J2EE" for only one.
so,how could I learn J2EE ?
3X!

Go download, install and use tomcat, http://jakarta.apache.org/tomcat/index.html . Go through its samples, write some jsp, build some servlets, write and understand taglibs and learn what a war file is. Doing this will get you started and you can do it all with tomcat.

  • How easy/difficult is it to learn J2EE yourself and importance for intervws

    Hi,
    I m in the process of learning Java [ I ve learnt quite a bit over the last few months and also took a 5 day class which definitely helped.] and have this opportunity to take/or not take, this class in J2EE...
    However, mainly due to $$ reasons... I am debating if I can just learn J2EE by myself instead of going to a class [ online sun tutorials, and other sources ] ....and how important it is to know this for inteviewing or could I just get by with:
    " knowing Java well and stating I have 'familiarity with J2EE' and want to do more work on J2EE."
    P.S. I am also preparing for SCJP.
    Any thoughts welcome.

    I guess the other way for a "beginner" in JAVA I really don�t see the need for talking EJB, Transaction... With few years of exp in J2EE, my strong feeling is only if you are really "STRONG" with the basics. Thinking about the HIFI stuff will be useful.
    Just imagine, if a beginner can do an EJB. How much can we trust on the stability of the system that is developed?
    It took nearly 2 years for me to appreciate the need and the usefulness of what J2EE or Sun with regard to J2EE has offered the developers. I have hardly attended any course on Java/J2EE. But I had to learn this stuff for pursuing a job and still living with the help of other developers around me over here.
    I have taken the full or maybe most of the potential that was given by the search engines that helped me in doing this good stuff. I also recommend that firstly become an expert on the basics and mastering the rest is simple.

  • Please, help me learn J2EE...point me out to better tutorials or something!

    Hi,
    Guys, I really need help in trying to learn what J2EE is.
    I've got prior knowledge and experience on Java (I thought), but ever since I came across the terms J2EE, EJB, JNI, JSP, JDBC and all that crap, I now don't know what I actually learnt!
    Please bear with me I beg of you! :)
    1.0: What I've learnt.
    ===============================
    So far, I've learnt (I think) the core/basics of the Java language, covering uhm...the basics up to GUIs, Arrays, IOStreams...yeah I think that's it.
    I code using notepad and compile them using the SDK...which up to now I still don't know if it is an SE or EE edition. It's j2sdk1.4.0 the last time I checked. I didn't use any IDE.
    I've done (school) projects like a Library System (involves loaning of books and charges etc etc), a Chalet Organizer (Loaning out chalets/rooms and charges etc etc) and an Appointment Organizer.
    So what was that which I learnt? Am I right to say that that is only core Java and nothing else and is next to worthless in the working world?
    2.0: Why I want to learn J2EE.
    ===============================
    Okay so why do I want to learn specifically J2EE? Well, most employment opportunities here require J2EE and EJB (and maybe some other alien terms) as prerequisites to being a "Java Programmer".
    I really need the job as soon as possible (for family's sake) and the job market here is already saturated with webmasters..
    3.0: What I have tried.
    ===============================
    Believe me, I tried for like 2 months already to try learn this thing on my own.
    I have followed almost exactly to the J2EE "Beginner's Tutorial" found on http://java.sun.com/j2ee/tutorial/ but no matter how far I read, I'm still just as clueless as I was when I was in my mother's womb about what J2EE is all about, even though I did the examples. I stopped somewhere in the middle of "Getting Started" because I realized I wasn't learning anything at all.
    4.0: Help meeeeeee...
    ===============================
    4.1:
    Can anyone please help me set my head straight and either point me to a REAL beginner's tutorial on J2EE and what the heck it is, or help explain to me slowly what J2EE really is and how to learn it?
    4.2:
    What's the difference between J2EE and J2SE?!? I initially thought that J2SE was simply just a smaller download which didn't include some of the heavier stuff that the EE carried, but boy was I wrong when that same tutorial asked me to install BOTH of them!
    4.3:
    Is it right for me to think that EJB are just files which are precoded to facilitate programming? e.g.:(I could've written up my own Date class instead of using the standard Date class that everybody uses.)
    4.4:
    What the hell is Jakarta Ant? Is it a builder and not a compiler, and may allow me to run built programs just by double-clicking on an e.g. executable? Like C++? So that I don't have to go to command prompt and type "java myApp.class"? (OT, but I think it's ridiculous that Apache has this and not Sun!!)
    4.5:
    Is there a simpler, much much much simpler example of a J2EE tutorial besides the overly vague tutorial "The Duke's Bank Application"? I need more examples of smaller scale maaaan... Better yet, is there a tutorial around that covers the very very very basics of Java all the way up to J2EE, step by step and with ample explanations?
    =========================
    Thanks all, I would really really appreciate any heads up you can provide me with.
    Sincerely, Kai.

    Lee and tsith - same fella -
    Run Tomcat as a standalone critter - the install of the current ver (4.1.12?) on a Windows machine sets it up nicely, and you don't have to worry about web connectors and stuff. Just create a few JSPs and dump them somewhere under the ROOT directory of your webapps directory and you should be able to hit them via a URL like http://localhost:8080/test.jsp (assuming you have it running on port 8080). Once you get your fill of the JSP thing, make a serrvlet and look into creating WAR files - then copy your WAR file into webapps subdirectory of your Tomcat installation and play with that. When you've had enough Servlet fun, then look into JBoss and making EAR files and you'll have all sorts of fun with JNDI and JDBC and all those other acronyms.
    Ant is just a build tool, not a compiler. Compiling simple java classes is no big deal, 'cause you just type javac MyClass.java or some such. But when you get into complicated build processes (like, compile these classes, making sure to include the J2EE jar and all the other jars I need, and create a WAR file, and deploy it to Tomcat) then Ant really helps.
    If you want help documenting your classes, the javadoc tool is for you.

  • How a J2EE web application access CR reports stored on the CR Server XI?

    Hi,
    I'll be working on some crystal report templates that will eventually be hosted/publish on the CR Server XI.
    My questions are:
    1. How my J2EE web application access those reports?
    2. Do my web application uses some CR API for the connectivity and integration?
    3. What will happen to the database connectivity of the report template? since the report are created locally.
    4. Can the report template be edited/updated on the server?
    5. How the CR XI login functionality be involve in the integration (web application ---> CR Server XI)?
    6. Is the J2EE web application be deployed on similar web/application server where the CR Server XI resides?
    7. What is the role of RAS, Universe, Business View Manager to this whole CR integration?
    I hope you can provide some guidance on this journey to Crystal Report world

    1) Your application connects via the Java SDK using the appropriate JAR files.
    2) It can.  You can set the database information at runtime or use the already populated information from Enterprise.
    3) Same as 2.   Typically when you save the report to Enterprise you set up the database information there so that it runs against the database you want without prompting.  You can change this via code to hit whatever equivalent database you want.
    4) Yes.  You would have to use RAS and the RCAPI to accomplish this via code.  You can also make changes in the designer and overwrite the existing report template.
    5) You will log in via code. The information on how to do so is in the SDK documentation, which I will link.
    6) It can be deployed to the same machine as CR Server, though we recommend against that.  Typically you will want to deploy it to a seperate web server and allow it to connect to the CR Server across the network.
    7) RAS can be used to run reports, as well as the page server.  The universe and business view manager are not directly used in code.  If a report runs against a universe or business view then it will use them for data, but you wouldnt do anything with them directly.

    You will find the Java SDK information under the BusinessObjects Enterprise SDK section.

  • How does J2EE SDK provide JNDI DataSource ?

    Still new to J2EE and working my way thorugh Wrox press "professional java server programming". Im using the deploy tool and im wondering how does J2EE provide JNDI names for a DataSource ? Im somewhat familiar with JNDI and I thought you had to use a directory service such as OpenLDAP to use JNDI.
    my questions then are:
    (1) What kinds of things can you do with JNDI without using a directory service ?
    (2) How does the J2EE SDK physically store references to a DataSource without using a directory service. In otherwords, how does the J2EE server provide for using JNDI names for a DataSource and is this a typical feature of J2EE containers ?

    i wish someone would answer this. i curious myself about these exact same things.

  • What's the flow of learning J2EE at present?

    I know that many techniques are emerging nowadays. I studied J2SE already. Now I want to learn J2EE development. Who can tell me what's the structure and the flow to study J2EE?

    start with servlets, JSPs, JSTL, and JDBC. You can go a long way with those.
    when that feels comfortable, learn Spring.
    No need for EJBs.

  • Hi i want tp start learning j2ee can anyone suggest any book or site for th

    hi ,
    i am MCA final year student i wana start learning j2ee can anyone suggest any site or book for that.
    i know JSP n wana learn the remaining technologies in j2ee.
    what all does come under j2ee.plzz help.

    Hi Vikas,
    This sun site contains all the information u need to get started in becoming the best J2EE programmer.
    just browse under technologies...> J2EE (Enterprise Edition) there u'll see a lot of tutorials covering the J2EE platform..such as Web Services, portals...jsp, servlets, xml, xsl, JAPX, javabeans..e.t.c too many to mention.
    Also there are other sites that can put u on the run try IBM..it has good resources for J2EE programmers www.ibm.com/developerworks or http://www-106.ibm.com/developerworks/ .
    or simply open up google and type "Learning J2EE" or "Understanding J2EE" and what u'll get will stun you.
    cheers.

  • What book should I read to learn J2ee!!

    i find that j2ee turorial is a hell of mess!!there's not enough real sample code out there,definition is vague,is there any one who can tell me which book should i turn to or in what way should i familiarize myself with J2ee
    thanks!

    thanks,english is my second language,my native is
    chinese,so there may be errors!!No errors really. It's a little irritating to the eyes when there are no spaces after the comma or full stop. It's almost similar to writingasentencewithoutspacesinitthatmaynotbeintendedtoirritatesomeonebutitdoeseventually.
    is there any book which concentrate on real project?It depends on what your real project is going to use. You can start by looking at the introductory J2EE text and decide which part of J2EE you want to start with. Servlets and JSP are usually the easiest to start with.

  • How learn to program in xcode 5.0?

    Hi everybody
    I would like to start programming in xcode, but i don't know any other programming language yet.
    I once bought a book to learn it all at once (objetive c with xcode) but it was dated and it was for an old
    Version of xcode.
    Now i wander if i should learn the old xcode 4, or  start at once with xcode 5?
    If you also have good tips for (e.g. Good (free?) guides, or books, or ibooks, or videos...) i would really
    Appriciate it if you could share your experienced thoughts with me!
    (I apologize for my typingmistakes, but i speak Dutch as first language)
    Thank you very much!

    Have a look to the Mac Developer Center (developer.apple.com). There you will find a complete Mac Developer Library with lots of documents. Reading the "Getting Started" section is the best initial step to get a general knowledge.
    More specific help can be found on the programming guides, always on the Developer Library (in the "Guides" section).
    If you need a general overview on Objective-C, I suggest you to read the following book:
         "Become An Xcoder - Start Programming the Mac Using Objective-C" by B. Altenberg, A. Clarke and P. Mougin.
    It's an extremely simple and basic text, but very clear and useful at the beginning.
