Why is getting a LWJGL applet to display in the browser utter hell!?

Newbie & Debugging Questions
#1

I’m serious… I’ve tried… I put in hours a night for over a week and a half now, and I cannot get (http://kappa.dreamhosters.com/bubblemark/bubblemark.html) to display in a webpage. I know it can be done, I can see it on bubblemark.html!

Do I suck!? Should I light my CS degree on fire!? Why is it such a bitter pill to place an applet running slick/LWJGL in a browser?

I tried following the tutorial here: http://ninjacave.com/lwjglapplet and I get one error after another. Is there anyone out there that knows how to get this thing running, I’m fresh out of ideas…

Hi

I’m sorry, but I know nothing of this subject yet, but you need to post some code. Something you’ve tried. Your main way of setting it up. We don’t even know if you’re using webstart or whatever. Give the guys something, and I’m sure they’ll help you.

Thanks Ultroman, I’ll post something up here in just a second. :slight_smile:

So basically this is what I’ve got:

I’m sure many of you guys area aware… but I didn’t write any of that code, and I plan on rewriting it once I can get the applet working in a browser.

applet.html

</body></html>

When I run the code, this is what I get:

java.lang.ClassNotFoundException: org.lwjgl.util.applet.AppletLoader

I’d really appreciate any help… Like I said, it’s going on two weeks, and I’ve told myself I’m getting this game done one way or the other… lwjgl seems like the only way to go for what I’m trying to do though.

Works fine for me.

EDIT:

Same setup and everything!? man… what am I doing wrong : /

This might be helpful, I don’t know:

Ok, I added the following files to the /bin directory:

and I now get the following error:

I also noticed the following in the output:

–no lwjgl natives files found

  • I placed ( linux_natives.jar, windows_natives.jar, solaris_natives.jar, and macosx_natives.jar) all in the bin directory… still get msg.

– java.security.AccessControlException: access denied

  • I’ll try signing the .jar file and see if that fixes this problem. (I thought it was signed)

The link you put at the top seems to work fine for me, the applet loads fine?

#10

The link works fine for me as well… but that’s not something I put up… I’m trying to duplicate what they did on that link.

That bubblemark applet is pretty old now and doesn’t use any of the latest slick/lwjgl stuff (there have been tons of bug fixes to both libraries since).

I’d suggest you download the LWJGL Applet Package from the downloads page and start from there as it contains a working applet example inside.

#12

Well it looks like I’m actually making headway :slight_smile:

When I run applet.html, It will display a popup asking the user if they want to run this signed applet, then windows asks if I want to block the applet.

After clicking yes to run the applet, and then clicking “no, don’t block”, I get the following error:

Anyone know what’s wrong with this? or how to get around it?

I got it working!

Thanks to all that helped me, especially Nate and ctomni231

Now I can finally begin reworking my game :smiley:
