Puzzle

[Craban]

I played with paths and 2D graph approximation to create a random jigsaw puzzle shape. The result is here: http://secretpaste.org/puzzle/pic1.html

Currently this is considered a beta. It is and will be free to use. Parameters control the picture and number of tiles. Just have a look at the HTML code.

DiTo: I hope you don't mind I use a picture you posted here. If you have any objections let me know and I'll replace it.

It never loaded for me. IE8. anyone else?

You need a Java plugin and as I used the simple old-style APPLET tag it won't warn if you don't have a Java plugin installed.

Hmm, maybe I should switch to the object tag instead.

I tested with Firefox, Chrome and IE8.

[Slipstone]

No joy at all...

Using Firefox - got message saying applet loading had failed

then this:

Oops, there are still Java 5 plugins out there?

I assumed that everybody uses Java 6. :(

[Greebo]

The Java app failed to run and threw up an error.
I'm using Ubuntu linux 9.1 (Karmic Koala) and Firefox 3.5.7 with Java version 6 update 16 (The latest update at the moment is 18 but 16 ought to be okay I would have thought)

[Craban]

Well, that should work. Can you please send me the stacktrace (the console message that is)?

Thanks for all the feedback. It's very appreciated.

Firefox 3.6.1 : Your browser does not support the applet tag.
:-(

[Greebo]

The error details I get are:-

@Greebo: There was a text file in the jar and that may have caused some issues. I changed it to pure code now so it should work for you.

@astringues: I changed the html from applet to a more portable way using Javascrïpt. From what I found this is the recommended way to start an applet (found on java.com).

[Craban]

Are there more Java 5 plugins out there? As soon as you get an error saying the class version is bad it's the runtime version. I just thought about using a JDK 5 but then I saw it has already reached it's end of service life so I'm a bit hesitant to jump on this old wagon.

[DiTo]

I love it Craban, just use them to your likings

[Craban]

Cool, thanks. And that implies that at least for one it's working ;-)

[DiTo]

hehe, well it took me more than half an hour to solve it, so .... Wonderful Craban, much obliged

[Greebo]

Hmm - I still get the same error info except the final section

gets repeated. I think I'll try closing Firefox and restarting it - maybe it's having a funny turn!
