    The Java on the client knows what version it is.
    It can check what version the applet was compiled with...each class has a version stamp identifying the Java version it was built on.
    The applet tag (I think, or this might be jnlp) can specify a version of Java to use.
    Please do not ask for code as refusal often offends.

    Thank you for your kind answer. I am looking for something more specific: how does java know when he's up-to-date when facing an applet? Java shows a pop-up when he's not up-to-date, i'd like to know where he asks if he is up-to-date or no. I know this may be an unusual question
    Thanks for any help i will receive :)

    No it doesn't.
    It only does that if the applet requires a later version of Java.

    I'm pretty sure it doesn't do an update check whenever it is started up.

    Ok, thank you. So this is my environment:
    i have 1.7.0_17, the site uses 1.7.0_21.
    The pop-up "Your version of Java is insecure... " appears: Does Java Checks its version on a particular site when facing an applet?-javapopup.jpg
    How does that pop-up come out? What does Java check? Do u know how can i stop this from appear? Even touching the registry?
    Thanks again

    Because it that was added into various browsers because of security flaws in u17.
    Apple went so far as to completely disable pre-u21 Java from executing.
    You can stop it from happening by updating your Java.

    Thank you, but i must not update my Java (it's the policy - i know it's strange). Thank you for your support, I'll keep searching for that site where Java asks for the latest version!
