Re: Creating Document Bundles in Java

Strange.

 .xyz extension to a FILE works. The bundled Java application launches as expected. 

 .xyz to a FOLDER does nothing at all. Opens as a regular folder and the Java app bundle is not called.

I restarted the computer. I used .truemediapackage instead of .xyz but can't see how that would effect anything. pList is shown below.

You can simply create a directory named with a particular extension (.xyz), and then claim that file type in your app's Info.plist. As long as your bundled app and it's claimed file association is known to Launch Services, any directory with that extension will be your "document" format. It is also the only reliable way to ensure that your app is launched when the file type is double-clicked on.

We actually use this exact technique in "Java Preferences.app" to claim .jdk bundles.

Thanks for asking!

Trying to create an app that creates document packages. You know, like application bundles but for files. Have an idea that depends on this function.

Do we have access to NSFileWrapper in Java 1.6 or 1.5?

No, there is no bridge to NSFileWrapper in Java. What are you trying to do?
