Time to learn...... Java

Hi all,

ok. The train has catched me.... and i'm willing to learn Java / JSP / WebDynpro and all the stuff that is related to Java and SAP.

I have some questions what you think is the best way and the best books around to learn the Java Basics :

- I want to use the SAP Netweaver Developer Studio to learn Java. It's based on Eclipse. Is there any book around for learning Java with Eclipse ?

- What book to you think is worth to read about Java ?

      That was exactly what i mean.

      OK. I have this book. I i also never heard of a "Sap NetWeaver Developer Studio for Dummies" book.

      Ok.

      Thanks to all.

    Hi Henning,

    you want to learn "alltogether now", but - begin at the beginning...

    Start with Java. It really doesn't matter what IDE you use, for the beginning, they are all more or less the same, so no need to be focused on Eclipse.

    When you have got the feeling that you are somehow "fit" in Java, start with web development.

    If you have made this step, go on with further technologies like WebDynpro (even if WebDynpro is sometimes sold as "Programming almost without programming", I wouldn't advise you to start which such a technology, it would contaminate you).

    See http://www.javashelf.com and http://www.javaranch.com for books.

    Hope it helps

    Detlev

    PS: If it was helpful, please consider rewarding points. Thanks in advance!

      Hi Henning,

      as Detlev said, go, learn the basics first.

      I would recommend the following books (and they are good preparation if you think about a Sun certification):

      - Sun Certified Programmer & Developer for Java 2 Study Guide

      - Head First Servlets & JSP

      These are from the founders of javaranch.com and are even fun to read.

      Don't think about developing portal stuff or web dynpros without having a good knowledge about java & servlet basics.

      Regards, Karsten

    Hi Henning,

    You really don't need a book to learn Java.

    The only three url's you will need in a very long time are:

    http://www.javasoft.com (same as http://java.sun.com)

    http://www.javasoft.com/tutorial (THE tutorial, which you can download as well).

    http://forum.java.sun.com (a forum where you will find answers and examples to most of the problems you will encounter).

    Since the start these three places have been so much more helpful than any books in learning the language and also updating the knowledge about new features and doing troubleshooting.

    Also they don't cost anything so it is a fairly good deal 😉

    There are a number of books about the usage of Eclipse, but again, as stated before just concentrate primarly on the language, the tools are a lot easier to learn once you understand the language they offer features for.

    Your biggest challenge (but by no means unlearnable) is the Object Oriented concept of Java. Especially if you come from a procedural background.

    Good Luck with your learning experience!

    Cheers,

    Kalle

    Hello Henning,

    from your name I guess you are german. There is a very good online book for learning Java with eclipse (after all german language only, I think):

    http://www.galileocomputing.de/openbook/javainsel4/

    I use this as reference over and over again.

    Cheers,

    Timo
