Mozilla/Blackdown

[Jörgen Cederlöf]

The goproblems Java applet doesn't seem to work at all for me. I have tried it during the last months with the newest versions of Mozilla (currently 1.2.1) and Blackdown Java (currently 1.3.1_02b) in Debian Unstable. Sometimes it crashes Mozilla completely, today it just seems to freeze the applet window. It is never playable. Other Java applets works fine.

that's unfortunate, but there's not much i can do. an applet should never crash java or the browser, so clearly it's blackdown's bug, not mine.

When Mozilla crashes, there is a Mozilla/Blackdown bug, yes. There might also be a bug in your applet which triggers this bug, or Blackdown might crash for perfectly legal applets. It doesn't really matter. What matters, for me, right now, is that I really want to try some Go problems, but I can't. And there must me many more people with the same problem.

It might be possible to create some workaround in the applet to make it run on Blackdown? (Don't tell me you haven't done any workarounds in the HTML/CSS to make it run on different browsers:) ) Or there might be a different Java plugin that works? My Java knowledge is close to zero, mainly because I don't like problems like this one.

yeah, there's surely some way to make it run on blackdown. since i don't have a linux box right now, i can't do it. however, the applet is open source so anyone is free to debug it.

once i worked around a bug in apple's java implementation so the applet would run on macs. it was a pain. i wish java VM's weren't so buggy.

I also have problem s viewing the goproblems on the site with opera and mozilla. I have previously learned that Opera is quite strict in requiring correct html in order to function properly. I tested the webpage with the 360-problem (the EASIEST problem) on http://validator.w3.org/ and the result
(see: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.goproblems.com%2Fprob.php3%3Fid%3D1703%26psetid%3D9930 )
and it is not correct html (but probably easily correctable).

Somehow I doubt that incorrect html would make a java-client crash, but suspect (due to previous personal experience) that a large portion of the problems users run into on the site is due to the incorrect html.

Fortunately I have netscape and have learned that goproblems.com really rocks! Thanks for a great site.

Hi,

I am using Opera and the applet crashes when I try to see a problem on the site. Meanwhile, the same browser can very well see the problems "off-line", after downloading the tar.gz file.

Is there the same applet in both cases? Or not?

Cheers,

yeah, it's the same applet.

there's some tricky javascript in the problem page to try to figure out the size of the window. that causes some browsers problems.

when an applet crashes, it should give you an error message in the java consul. what does it say?

Could there be a problem with the authentication on the proxy?

I tried with Opera on a computer that is not using proxy authentication to go on internet and the applet works fine.
