    Beginning S60 development. Is Java a good starting point?

    hello everyone, I hope this type of thread is ok.
    I want to begin learning developing applications for my S60 3rd phone(E61i).
    Since I am just starting, I want to "play" around a bit, like test using the camera, messaging, etc. Can I access those features with Java?

    Java is a good starting point, if you want a less steep learning curve than with Symbian C++. It is also a good starting point, if you want to develop for other devices than Symbian based.

    Note that with Java, the full power offered by native Symbian/S60 C++ development is not available to you.

    However, the easiest way to get onboard is probably by installing S60 Python and starting with that.

    yup as mentioned above java is a good starting point...
    just take into account that u wont be able to access much information and control regarding hardware (think in terms as : battery levels, bluetooth signal strength etc)...
    so Java is kinda simpler to learn but depending on what application u want to develop u'll have to take into account the limits of J2ME...

    Hi ares623! Welcome to Nokia Developer Discussion Boards!!

    Your test area like accessing Camera(JSR 135), Messaging(JSR 120, 205) are quite possible with Java ME. But keep in mind that Java ME have certain limitations as well.

    You can read more about Java ME application development here.

    Hope this helps!

    thanks everyone.
    I think i'll stick with Java since I have a little experience with it on the desktop and it's syntax is familiar to me.
    Will the apps I develop be cross-platform by default?
    What are those JSR ###'s?
    I downloaded the S60 3rd (no FP#) SDK and NetBeans mobility, are those enough to get started?

    If you are not using any device/vendor specific API's your apps could work cross platform. Also make sure that the API's that you are using in your app is supported by the phone as well.

    Java Specification Request (JSR) is the actual description of proposed and final specifications for the Java platform. JSRs are reviewed by the JCP and the public before a final release of a specification is made.
    More info : http://jcp.org/en/jsr/overview
    http://jcp.org/en/introduction/overview

    The SDK's that you have downloaded are ok to get started.
