Mac OS X Java Update Causing Problems with Java Web Start?

The most recent Java auto-update through OS X (Leopard) is causing some problems with Java Web Start, the program used to launch the MDO Transporter program. If you’ve gone through the update and your Java Web Start is no longer available it means that the update wasn’t completely successful.

A symptom of this is trying to launch a Java Web Start Application (Transporter for My Docs users) and having it open something that looks like a text file.

Fortunately there is a fairly simple solution to the problem. You can manually re-install the Java Update from this Apple location.

Uploading Keynote Files to your Account

Unlike PowerPoint, Apple’s Keynote uses XML and folders called “bundles” to package multiple files and folders into a presentation.

As a result, when uploading or downloading you are actually uploading and downloading a folder structure, and a lot of files.

To make things trickier, OSX and Safari understand the special nature of Keynote “bundles”. The Finder will treat the folder bundle as a presentation, and if you try to upload one to My Docs Online via Safari, it will be grayed out (you can’t select it for upload).

If you use FireFox, you can select the “presentation” but it won’t upload, because it isn’t really a file.

However, if you use the Transporter to upload the presentation it will upload the entire bundle (all folders and files).

Then, when you want to download the presentation to another Mac, use the Transporter again to “download folder” and the result will be a working Keynote presentation.
