Jar not working?

General Discussions
#1

I had a bunch of applets I wrote that played various games, I turned them into webstart apps because that seemed the way forward. Then the Java security model changed and none of that worked. I now just provide a link to the jar and let people save the jar locally and then run it from there. Unfortunately it’s difficult to really test what happens on other peoples machines.

A friend has a apple computer and tells me he’s enabled Java and lowered the security but can’t get my chess program to work. Any body know why? or what I can do to fix this? Is releasing things as a jar the best way forwards for me? it’s such a pain having to get people to download jars when the original code worked perfectly in their browser. It’s also a pain because now I have no idea what version of the code people are running - with webstart I could ensure that everyone had the same bug fixes etc.

Many thanks

PS can anyone confirm that my little connect 4 program works? on apple or linux or PC?

Thanks for confirming it works on Windows guys - I was beginning to wonder if it only worked for me.
Did you try the connect 4? (you don’t have to play it but just say if it starts up).
Can anyone say if the chess works on apple?
Is there a better way of releasing the programs? downloadable jars seem a bit naff to me.

They both work on mac, though I’ve to shake those windows and minimise and reopen the windows to get those painted.

I’ve not lowered any security settings.

I’m confused then. My (not so IT literate) apple friend sent me the following error and said it just wouldn’t run on apple.

PS - I’d just like to say thanks to you all for replying so fast - I’d didn’t expect any responses for a few days!

Ask him what the version of Java he’s running. Maybe it’s an old version I guess. Could you ask him to show the terminal output?

#8

I’ll ask him and get back.

Maybe you can try this trick (OS X 10.8 and later):

He mentioned that he’d updated his OS (on apple) and it must have upset Java. He then uninstalled Java and re-installed and things worked again. I’m not sure why this would of happened but at least I have an answer if anyone else has the same issue. Thanks for helping.
