I have my Windows work computer set up with JDE 5, but the plugin for the Mac OSX Eclipse on my home computer is JDE 6 and I can't seem to find a source to download it from.
I found a blog post about MacOS BlackBerry development, but it is from before the official MacOS plugin was released. Anything new on this front?
Ahh. Seems like Apple removed java 5 and below from Snow Leopard (10.6). Leopard (10.5) still supports 1.4.2 and 5.0 and 6.0. You can find them in "/Applications/Utilities/Java Preferences.app".
RIM has only released an Eclipse Plugin on OS X. The JDE is Windows-only and probably will always be Windows-only (RIM is trying to phase out the JDE and is encouraging all developers to move to the Eclipse platform).
Keep in mind that the Eclipse plugin for OS X is still VERY new and still has some rough edges - I tried it out and it crashed on more than one occasion! Also, there is no simulator available on OS X yet so you'll need a physical device to deploy and test on (I think it has to be a 9800 but I could be wrong). RIM has promised a simulator on OS X but probably not for another 6 months or so.
