问题
I would like to associate a specific file type with my application, so when I double-click one of the files of this specific type, my application opens. This works just fine, but the file I double-clicked does not get passed as an argument to my program.
If I for instance associate my application with txt files and I double-click todo.txt, my application opens, but I have no idea which txt file I double-clicked.
From what I can read, this is how it's supposed to work on OS X, and instead of relying on the default behaviour (how it works on e.g. Windows), I should use ApplicationListener.handleOpenFile(); from com.apple.eawt. When I attempt this, however, I'm being told that I'm not allowed to do so:
Access restriction: The type ApplicationListener is not accessible due to restriction on required library /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Classes/ui.jar
In another question here, one guy says he found the solution on some Chinese website, and the other says it isn't legal according to Java's license agreement terms.
I can find no mention of it in the Mac OS X Developer Library, and whatever links might seem useful on this site about JAR Bundler just sends me to a dead page on Apple's Developer site.
What am I missing? Is it supposed to be nearly impossible to do this, even though it's trivial on other operating systems?
It's probably worth mentioning... since JARfiles can't be associated with programs on OS X, I've created an OS X Application Bundle using JAR Bundler; an Apple tool made specifically for the purpose of being able to treat Java applications as native OS X applications. Using this is what allowed me to associate the file type with my application in the first place.

I've used OSXAdapter for preferences, about, and quit functionality. You might be able to leverage it's introspective approach to avoid the restriction. As com.apple.eawt.ApplicationListener is deprecated, you might try com.apple.eawt.OpenFilesHandler instead.
