    Question Java for the web?

    Hi all,

    I have learned Java at school to create offline programs, such as command line programs and swings.

    And now, I am wondering what kind of Java is used for the web. One of job requirements on many of job postings for web developer is Java. So, I wonder if it is Java applet, or something else that I didn't learn from school?

    Regards,
    Dhimoet

    Java used for the Web is still Java, however there are technologies that go with it.

    Basically when you make Java Web pages you can do it a few different ways, one was is to use a Java Servlet while another is to use a JSP (JavaServer Page). A JSP is basically a high level Servlet that allows you to mix in Java code with your html in the form of Scriplets or JSTL Tags (Special Java Tags that resemble HTML Tags).

    If you are looking for more information on this subject, theres a decent overview here: http://java.sun.com/developer/techni...ols/webapps_1/

    You can still do Java Applets however I generally think of JSP and Servlets when people say Java Web Development.

    Hi welsh,

    Thank you for the answer. I have looked at the page you gave, but unfortunately I could not imagine of any simple real life application. It is hard for me to learn something when I could not figure the final state.

    If it is possible, could you also give me some examples?

    Regards,

    I'm fairly positive that for the Air Canada website for booking your flights is Java. Go to http://aircanada.com/en/home.html and search for any flight.

    I know for 100% Certainty that the Build Your Nissan for NissanUSA located at http://www.nissanusa.com/buildyourni...build/2012/ZRD is developed with using Java.

    Another one is UnionBank for their online Banking website: https://banking.unionbank.com/web/Banking/SignOn.jsp You can tell for sure its done with Java due to the .jsp extension.

    Another big thing with Java for the Web is developing Enterprise level Applications, for that there is Java Platform Enterprise Edition or J2EE which you can read the wiki here: http://en.wikipedia.org/wiki/Java_Pl...rprise_Edition or you can see the sun page here: http://java.sun.com/j2ee/overview.html

    Hi welsh,

    Thank you again for the awesome inputs. I searched a flight (from toronto to vancouver) and noticed that the file extension is .do. I found this on the internet:
    The .DO file is used by the Oracle Application Server to dynamically make a HTML page (just like a PHP server uses a .PHP file).
    Thanks to you now I know the general idea.

    Regards,
