"This sentance no verb". Similarly there's a problem with your question. There is a specific thing known as applet which implies a Java program designed to execute on a web browser - client side. Follow the link for the full scoop on "applets". Your language references vary between client-side and server-side but none are "applet"s. JavaScript normally executes in web browsers and is perfectly fine for what it is - the defacto web browser scripting language. VB Script is Microsoft's proprietary language which also executes with Microsoft web browsers. Both are browser scripting languages (JavaScript is obviously preferrable) and are useful as long as you don't comprimise your functionality by depending on them. I gather that PerlScript is a sort of add-on that ActiveState came up with. I understand it's supposed to allow Perl to run in a web browser but that's even less supported than VBScript (since ActiveState Perl isn't everywhere). So for client-side web browser scripting you mean to run JavaScript.

For server side there is a server side JavaScript but I think it's only used on Netscape's web server software. VB Script is again, supported by Microsoft on their IIS platform which is for many reasons frequently a poor technology choice. From there you go on into installable languages like the various mod_ packages (mod_perl and PHP included). And from there you go on to general CGIs which can be in pretty much any language.

I can't answer your usage question in any case but no one can answer the question until you're clear on what you're asking for. The literal interpretation of your question is that Java is 100% of all applet implementations.
