    Default about to launch a new website with several applets

    Am I going to have trouble when launch a website with several photo slide applets?
    I mean people will not be able to see the photos because:
    -do not have java installed?
    -there will be security issues where users have to grant permission which the refuse;
    -or what ever reason I am not thinking of (I read some comment ones saying:
    "where have all the applets gone?"

    applets were very popular about 5 years ago, right?
    Has that changed?
    Did eg java-script take over some stuff?
    (Am I political incorrect to ask these things at this forum.....)

    Actually, I still occasionally write applets. But I believe most web servers today are based on Java Server Pages (and similar technolgoy like Active Server Pages) and Servlets. Here is a link to a pretty good resource. I went thru the entire site over a year so I definitely recommend it. Free Online Version of Core Servlets and JavaServer Pages (Second Edition) in PDF. You will need to have the Enterprise Edition of Java installed to write client and server side code.

    If a visitor falls into one of the many categories that don't allow them to see an applet, they won't see your website content. Its that simple. If you are dead set on this route then break down and evaluate how you can overcome each point of failure. For instance, if a user has an old version of java - meaning you should compile with a min-available minor version. If a user has Java disabled/not installed: provide an alternative. All this being said, in my opinion for simple conveyance of information which most websites fall into the category of, Javascript and css provide (this is my opinion here) a better, faster, cleaner, more maintainable client-side browsing experience, not to mention a more web-crawler friendly experience. For heavier lifting, sure applets (or better yet webstart) have their place. For something like a photo slide show, it's something that can easily be done with css/javascript

    Default Re: about to launch a new website with several applets

    Before continuing with the applet discussion, IŽd like to tell you some more about myself and my goals concerning Java. I am 56 years old and my forum activity will tell you that I was already doing things in Java several years ago. Than I learned Java for fun, but now I am studying java more systematically.
    I have no professional background in computers, I am a musician and a teacher at an important conservatory in Spain. But I believe firmly that Spain soon will get into a similar mess as Greece and I fear (as an immigrant) for my job (especially because music education is irrelevant for a diminishing society). I know I should probably be thinking about me be pensioned soon..... but as things go in Spain (and in other parts of this world as well) there will hardly be any pension fund left (grabbed by governments, controlled by international banks).
    So I am developing a series of plans and the website (with the applets) I am doing form a part of these plans. Java also fits into the above --without really knowing if I am being realist here--!

    I studied all basic issues of Java, from simple classes, to threads and streams and understand most of it (I believe). (I still have an issue with static inner classes since they form some kind of "mirrored logic"). Of course I am still far of being really fluent in java (which obviously shows the previous thread about "I get this enormous error message...."). So in this context you server link, jim829, might be interesting, but in conclusion of this personal intervention I should say that the Java-learning-process is still pretty overwhelming to me, so be patient in your helpful assistance please.

    Since I (partly) know Java I thought it would be fun to create the web photo slide show as an applet.
    Since I write it myself I set al my needs by picking up several parameters by using params.
    So the applet tag sets:
    -size of the photo screen (with automatic scaling);
    -background colour;
    -play/forward/backward buttons, or any buttons, instead using a timer (time can be set as well);
    -optional: a maximum of two text lines, commenting on the current photo,
    -and several fade outs cross over functions (still to be programmed/ copied) to make the slide show more attractive.

    -My next question, would be: can I do all the above stuff, using Flash or java-script or what ever?
    -How serious is my trouble concerning the applets when my real-estate sale website in six languages (Russian included) will go on air
    (where the applet show is of course important)?

    thanks for all your help
