Unable to get Applescript Engine on some computers
In my code I have: ScriptEngineManager mgr = new ScriptEngineManager(); ScriptEngine engine = mgr.getEngineByName(AppleScript); this works fine for me, but for some customers in returns null for engine. We are using Java 1.8.0 25.0-b69 64bit (build 129) Customer was on Mac OS X 10.9.2 x86_64, I've upgraded to same version still don't get the problem. Applescript does exist because earlier in my code I run some applescript using osascript and Runtime class and that works fine Any ideas ? Paul

I assume you have /System/Library/Java/Extensions/AppleScriptEngine.jar but some of your customers don't. The JDK does include the AppleScriptEngine but is missing the service configuration file that is needed to locate it. There is a bug open for this but it does raise the question as to whether the JDK really needs to bundle this scripting engine or not. -Alan

This is what I did and what I made available on github at… https://github.com/mik3hall/AppleScriptEngine All you really need are the jar and dylib. Put the dylib in the application's MacOSX folder. appbundler adds that to LD_LIBRARY_PATH. Put the jar in the application's Java folder, this should get it into class path. Done and should work on any configuration. 2). Fix the openjdk configuration error yourself. This means adding the AppleScriptEngine entry to the config file in resources.jar. I believe the bug report I gave earlier details how to do that. 3). Wait for openjdk to correct the configuration file in resources.jar My understanding on that one anyhow.

Re: Unable to get Applescript Engine on some computers
It's probably sufficient to put the necessary configuration anywhere on the classpath? I doubt one actually has to hack resources.jar?

As more machines come to exist which have only ever had Java 7 or greater on them we'd see this issue more often, unless it is fixed. Right now I think this masking makes it impossible to estimate how widely used this engine is.

If so then move it where because that directory is used by the extensions mechanism (all JAR files in there are searched). -Alan.

Ah yes, I renamed to .old file thinking that would do it, but moving it out completely does replicate the issue thanks Paul
Re: Unable to get Applescript Engine on some computers
From what I understand from working with the service loader framework in general if the relevant config file is present on the classpath, either loose as a file or in any jar it will be used. The file would be META-INF/services/something. Given that jar is in the extensions directory I think it will be loaded regardless of name. Try moving it to another folder temporarily?

FileAttributeView for tags and colors?
Hey there, I was wondering, wouldn't the tags/colors API in OS X 10.9 be a really nice candidate for a java.nio.file.attribute.FileAttributeView? Is an appropriate implementation planned? I wasn't able to find an RFE on https://bugs.openjdk.java.net Cheers, -hendrik

I wasn't able to find an RFE on https://bugs.openjdk.java.net Again fwiw, my trz package has support for a lot of different OS X file attributes, including old 'classic', file colors. I sort of liked the idea of color being a file attribute myself. Not your usual one. I am not 10.9 yet but when I get there if this API concerns this same sort of thing I would be happy to include it in trz anyhow. It is quite possible to add something like this along with a 'pass through' type file system. So you could possibly come up with it yourself without excessive effort.

For my own needs, I will probably just roll my own (since the API is trivial), but for the future I wouldn't mind seeing APIs like this exposed through the regular JDK. And if nobody asks for it, it never gets done...so I ask. ;-) Cheers, -hendrik
