   Hmm…there might be a problem. Zip uninstalls correctly but when launchng the app the icon appears in the dock, then disappears after a second or so with no message displayed.

   This is on a MacBook Pro 2.4 Ghz Intel Core 2 due (running Tiger).

   Interesting note: when I tried to unzip the BingoCardCreator.jar file, I got this:

   Note that filesystems are case insensitive by default on mac, and you have both a b.class and B.class file. That may be the source of the problem.

   Thanks much. That is a relic of the obfuscation software I use. I turned off uppercase filenames and re-built and uploaded. Does it work now?

   There is no more collision with the file names, but I still get the same error as before. The problem must be somewhere else.

   Ahh, I know what I did — compiled on 1.6 on my laptop when the Mac version is set to run as 1.4 for compatibility reasons. Let me fix that and try again…

   Browsercam.com lets you remote into a Mac.

    Ps/ I don’t understand why you would use zip. The vast majority of mac apps seem to use compressed DMG (disk image) format.

    I use a little utility called DropDMG to take the pain out of creating DMG files.

    Ps/ Java, write once, debug everywhere? ;0)

    You know it. I’m going to see if I can’t get Browsercam working, although they don’t appear to be letting me log into an account which can run arbitrary Java programs. Grrr….

    The only reason I use zips instead of DMGs is because I can edit a zip on my PC and I don’t know how to edit a DMG on my PC.

    Ahh well, Mac users get to wait a week, this website is going live today.

    Mac minis are fairly cheap and connect to PC USB keyboards and VGA or DVI monitors. They are quite adequate for porting if you up the memory to 1GB.

    My main issue would be where the heck to put the thing… I recently moved into a Japanese apartment which is shoebox-esque…

    If you can’t fit a mac mini, then I’m amazed. I knew Japan had small [everything]s, but still…

    I imagine someone’s got a spare dev/test box they’ll let you VNC into (sadly, I am not one of them).

    Mac mini’s are about 15cmx15cmx5cm – the size of a overfilled sandwich. If you buy a usb/dvi KVM switch you can even share your Windows keyboard, monitor and mouse.

    OSX 10.4 comes with a VNC server. It needs to be enabled by the mac owner, once enabled you can use VNC to remote control the computer.

    How do you make 1.6 the default VM on a mac? I installed the download off apple’s website, but I still get that error!

    TeamViewer runs on Mac and windows. If u have a Mac and install this please email me ur code because I need to convert a DMG file.
