Given no one has tried answering this I would either assume sandboxed settings aren’t different or people who know if they are different aren’t following the list anymore. It doesn’t seem all that bad an idea to me. With applications getting more complex having different possible settings for some of these properties could make sense. Say signed and sandboxed versus not MAS targeted could have different user.dir settings. Meanwhile, since I am not currently MAS targeted I will see what I can do with Application Support, although that is really not all that different from using user.home/user.dir. javapackager user.dir I think had user.dir set to the app path itself. Useful for read access of your own app files, but not for storing data assuming you are in the Application directory with no write permissions. Again since the Apple jvm’s (user.dir was always the app's directory as I remember) I think this setting has changed a couple of times. javapackager may of changed again I vaguely remember. My last couple tries with javapackager didn’t successfully get me valid application bundles at all, but it wasn’t anything I needed critically. I will take a look at your links. Thanks. Michael Hall
nio.2 file attributes for OS X
fwiw, After a recent discussion I have updated my github trz project, the ant file now at least includes something to compile the java, which after a couple tweaks it did last night successfully. Still a little thrown together so if anyone tries it and has any problems please let me know. It must of been very thrown together last time, it was a mess. In the interest of ‘eating my own dog food’ I have just added the jar and dylib to my HalfPipe app. I intend to do some things with external files and I think the Mac specific file attributes in trz could be useful. The app does still launch so changing the default FileSystemProvider appears to cause no initial problems. For about everything except additional OS X specific nio.2 file attributes it should fall back to the jvm provided default FileSystemProvider. https://github.com/mik3hall/trz <https://github.com/mik3hall/trz> https://www195.pair.com/mik3hall/halfpipe.dmg <https://www195.pair.com/mik3hall/halfpipe.dmg> Although HalfPipe with the nio.2 related hasn’t been uploaded yet.

OK, should be a long term fix unless they decide for some reason changing this should not be allowed and that is for some reason the ‘expected behavior’. I think one of the posts I had a url on said it doesn’t work on Linux systems either. I could add it to mine based on your code, or you could I guess, the source is on github. As I remember you would need to specify my OS X specific filesystem(provider) as a jvm launch parameter. It is the same as the usual I think (falling through to the default filesystem(provider) for about everything except adding the additional OS X file attribute views. Again a lot of the api’s don’t support update as I was sort of waiting for interest on the read only attributes, which hasn’t yet really been indicated, before making the code ‘more serious’. It does have a currently non-functioning WatchService, so if you need one of those that works it might not be for you. Although, I may of had a property switch or something that let you fallback to the default there as well. It’s been a while for most of this, I don’t remember. Michael Hall

I’m assuming ‘what it’s documented to do’ means it changes something other than
finder creation date/time.
Maybe the stack overflow link I posted wasn’t concerned with changing Finder
related.
These suggest using the ‘touch’ or ‘SetFile’ commands could accomplish this...

My trz code does support some cocoa/NSFileManager type attributes…

<https://github.com/mik3hall/trz/blob/master/src/us/hall/trz/osx/test/MacAttributesTest.java>
shows junit tests of some of the api’s supported.
For Cocoa it has this.
@Test
public void testCocoa() {
try {
File f = new File("build.xml");
Path p = f.toPath();
Map<String,Object> attrs =
Files.readAttributes(p,"mac_cocoa:*");
assertEquals(17,attrs.size());
assertFalse(((Boolean)Files.getAttribute(p,"mac_cocoa:NSFileBusy")).booleanValue());
assertEquals(Files.size(p),((Long)Files.getAttribute(p,"mac_cocoa:NSFileSize")).longValue());
attrs =
Files.readAttributes(p,"mac_cocoa:NSFileModificationDate,mac_cocoa:NSFilePosixPermissions");
assertEquals(2,attrs.size());
}
catch (IOException ioex) { fail(ioex.toString()); }
}
Updating may not be supported. But could be added if you or anyone else want to
use it. I didn’t want my first feedback on the code to be that someone tried it
and something got messed up on their machine. “Hey, I tried your code and it
turned all the files orange”. (I think I did include that possibility for
FinderInfo though…
Files.setAttribute(p, "mac_finder:label", "orange”);
it was just kind of fun).
This would do all the native for you and allow you to do what you want in the
nio.2 way. Assuming I can get it to work. Despite the last stack overflow post
it doesn’t seem like it should be all that difficult.

I looked at the last appbundler source I have downloaded, which may not be

To be sure you could download the latest and check yourself.
From this, APP_ROOT would not work, you might show how you specified fullpath?
Path wrong could still be a reason it doesn't work that doesn't mean a bug.
yes it runs through command line and I'm trying with both 1.8.0 and u20
In the most current version of the source that I have, again possibly not the
actual latest - then it should work application launched.
The source has…
// Get the VM options
NSArray *options = [infoDictionary objectForKey:@JVM_OPTIONS_KEY];
if (options == nil) {
options = [NSArray array];
}
…
// Initialize the arguments to JLI_Launch()
int argc = 1 + [options count] + 2 + [arguments count] + 1;
char *argv[argc];
int i = 0;
argv[i++] = commandName;
argv[i++] = strdup([classPath UTF8String]);
argv[i++] = strdup([libraryPath UTF8String]);
for (NSString *option in options) {
argv[i++] = strdup([option UTF8String]);
}
So it just copies in the options, no editing, skipping or additions. Should be
just like command line.
So if path is good, and it doesn't correctly handle the splash option, then
something is broken somehow that isn't broken in command line and you probably
have a bug report?

this is my problem, I'm not able to see other folders in the same
/Contents/Java. it seems the classes are executed as part of the classpath
and not the working directory that it should be in.
I believe the way this works is that any jars in the Java directory are added
to classpath _but_ the Java directory itself is not classpath. The Classes
directory it contains is in classpath.
For example:
set java.class.path
java.class.path=/Users/mjh/HalfPipe/HalfPipe7.app/Contents/Java/Classes:/Users/mjh/HalfPipe/HalfPipe7.app/Contents/Java/antlr-2.7.7.jar:…[Other
jars in the Java directory automatically
added].../Users/mjh/HalfPipe/HalfPipe7.app/Contents/Java/weka.jar
Notice Java directory itself not there. Java/Classes is there.
So that you can access resources off of that with something like…
try {
ClassLoader cl = new
java.net.URLClassLoader(new java.net.URL[0]);
BufferedReader rdr = new BufferedReader(new
InputStreamReader(cl.getResourceAsStream(Scripts/loader.js)));
jsEngine.eval(rdr);
}
catch (Exception ex) {
ex.printStackTrace(org.cmdline.common.Configuration.getSysOut()); }
Where Scripts/loader.js is located in the above mentioned Classes directory.
user.dir I would still suggest is not a reliable way to access application
files going forward.
i will try now with Joe suggestion to go with the new fx packager, it is
certainly the way forward.
If this provides equivalent functionality and is active this would probably be
the way to go. Given the time, I will look at it. Any handy OS X specific
documentation links would be appreciated.

Applescript does exist because earlier in my code I run some applescript using osascript and Runtime class and that works fine l don't know that it was precisely determined what caused this. Possibly some change in an OS upgrade where Apple removed something from their java distribution? Although we didn't know it, we were relying on the Apple code being in place. Your three options would be… 1) Provide the code in the jar and dylib yourself. 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.

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.

Requiring R_HOME to be set in the environment seems sketchy to me. At worst you should be able to set it through a system property, not rely on the environment. Is it open source? Maybe it could be fixed and contributed back. The ugly workaround might be to drill down through JNI to call setenv, if it can be done early enough. Given LSEnvironment not seeming to work at all. I should probably set up some other test cases and see if this seems to hold consistently. But given that, I am already considering the workarounds. The property is required by the native code, getenv(), where System.property not quite as preferred as in Java? Anyhow, current efforts on the 'ugly workaround'. Somehow do a setenv myself. Thanks.
