As far as I know, the 3DS cannot run Java files or other executables, and even if it could, you're running system homebrew on a 3DS at your own risk. This topic pertains to use of the 3DS browser for creating client-side apps in HTML/JS.
I use html,css,php,Java Script,jquery,html5(some),and css3(some) but you can use almost every web-base coding language but you just need to know what your doing :P
I have read through questions and thought i may aswell post the question answer.What is the exact width?the width is 300px<hr>what scripts are supportted?all scripts execpt java,flash and any you need a download for.<hr>what scripting language can i use?you can use all the avalible scripts
The width of the bottom screen is 320px and the top is 400px. There are a lot of stuff that isn't supported on the 3DS like HTML5 video/audio. Scripts that you should be using is HTML, CSS/3, JS. You can also use more than half the stuff in HTML5.
depending on what your doing, the html5 canvas can make alot of stuff so much easier. long story short, if you have a platform game, you just have to paint something like this only once http://i.imgur.com/p1KyoFn.png and there you go, using that image as the example, the 160 divs../images you were using before magically changes into 1 html5 canvas image. and moving that left/right is almost nothing.
thats actually a block game im making btw. 1 million blocks too.
is there any way to have the 3ds touch screen react instanting to mouse coordinates? like, on the wii u gamepad, there was a painting website where the very instant you touch the screen, you start drawing. but on the 3ds, you have to hold the touch screen for like 1 second before you can get the coordinates. is there any way around this? im sure i can make instant trigger effects, using a scroll bar since the 3ds reacts to those instantly, but i want to continually get the mouse coordinates instead.

That's not possible at all. On the Wii U and DSi it's completely different. The reason for that is because in order to get the coordinate is that it has to start highlighting on the DSi and 3DS, I don't know about the Wii U but the DSi highlights instantly and the 3DS takes 3 seconds to.
