hi everyone,

I hope I can get some info here, otherwise, please redirect to another more specific forum.

I'm deploying an application for Mac, it is not a common application in term of structure. It is basically an Adobe AIR application but started by a java class.

Here is the structure of the app:

/MyApp/Info.plist
/MyApp/MacOS/
/MyApp/MacOS/JavaApplicationStub (this starts the runnable jar)
/MyApp/MacOS/SomaUI (this is started by the runnable jar and starts the AIR app)
/MyApp/PkgInfo
/MyApp/Resources/
/MyApp/Resources/Java/
/MyApp/Resources/Java/MyApp.jar
/MyApp/Resources/icons.icns
/MyApp/Resources/rest of my air application...

when I type in the terminal:
java -jar MyApp.jar

java starts, start the air app (which is basically the content of a AIR app install: MyAirApp.app)

Everything works so far.

But when I try to start the real app (made with jar Bundler) by double clicking on it, I got:

LSOpenFromURLSpec() failed with error -10810 for the file /Users/romuald/Desktop/MyApp/MyApp.app.

I guess my runnable jar is not found?

Here is my Info.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist SYSTEM "file://localhost/System/Library/DTDs/PropertyList.dtd">
<plist version="0.9">
<dict>
<key>CFBundleName</key>
<string>MyApp</string>
<key>CFBundleVersion</key>
<string>10.2</string>
<key>CFBundleAllowMixedLocalizations</key>
<string>true</string>
<key>CFBundleExecutable</key>
<string>JavaApplicationStub</string>
<key>CFBundleDevelopmentRegion</key>
<string>English</string>
<key>CFBundlePackageType</key>
<string>APPL</string>
<key>CFBundleSignature</key>
<string>????</string>
<key>CFBundleInfoDictionaryVersion</key>
<string>6.0</string>
<key>CFBundleIconFile</key>
<string>icon.icns</string>
<key>Java</key>
<dict>
<key>MainClass</key>
<string>Main</string>
<key>JVMVersion</key>
<string>1.5*</string>
<key>ClassPath</key>
<string>$JAVAROOT/MyApp.jar</string>
</dict>
</dict>
</plist>

Can anyone tells me what I'm missing?

Thanks in advance.

I don't know that I can solve you problem directly, but I do have a pair of notes:

- Apple has been seriously depreciating the Cocoa-Java bridge that it seems you are depending on. I would strongly recommend finding another route for this.

- Why are you doing this fancy redirection using Java to launch an AIR application? I can't figure out why you would do that. If you can share your reasoning the group can probably come up with a better supported route of getting what you want done done.

[Romustep]

Absolutely, I'm using a java-AIR bridge (Merapi project). This bridge allows me to send and receive messages from java in AIR app (making me able to execute files and use the java-power from an AIR app). The java instance has to be started before the AIR in order to work correctly, so the best way is start java -> java is starting the bridge and then launch the AIR app.

Everything is working correctly on Windows and it is just a matter of having a app folder that is starting correctly the executable jar. As I said, when I start my executable jar from the console, java starts and the AIR app is launched. Only when I double click on the app (that should start that jar), it fails. I can see this error when I type "open MyApp.app" in the console, double clicking make it fail silently (I see the icon in the 1 sec though).

I can share files if someone would be kind enough to have a look, I'm a bit lost on that one.

Please help

Thanks in advance.

I'm mostly just an end user, but I'm wondering if, aside from looking up that particular error code (if you haven't already), you could try inspecting a working Java app package that does something similar to verify that your plist is all correct.

[Romustep]

Basically I used something similar I've already built using java SWT (with a startOnMainThread property, so it was working), but it doesn't work for that one. This app was starting a executable jar, exactly what I'm trying to do.

I believe something is wrong in the plist but I'm not pretty sure :/

Wish I had more help to offer.

Have you confirmed that everything (that ought to be) is set as executable?

[Romustep]

that's a runnable jar, so yes it is.

I think I found the problem and it is a java one. When java is starting the second app, I found out that an absolute path was working!

But impossible to make it work with a relative one, I tried everything.

So the trick is calculate the absolute path of my app, append the relative one I need and use those relative path to execute the other.

Not done yet, I'll try this evening but it should work.

Thanks for your help guys!

[Romustep]

Still not right, I can't get it work.

It means the path I get in Java using : new File("").getAbsolutePath()
is not returning me the one of the jar :s

Any idea?

[Romustep]

I finally found it, I post the solution here in case other non-java developer like me have the problem:

My first try was to launch the app using a relative path: no success

Second try was getting the app absolute path using in my main class:
String absPath = new File("").getAbsolutePath();
substring "/Resources/Java" and add the other relative path
still no success

The solution is using the Class.class.getResource():
String absPath = Main.class.getResource("/").toString();
// remove "file:" at the beginning and "/Resources/Java" at the end
absPath = absPath.substring(5, absPath.length() - 16);
// MyAirAppToLaunch is the script created by the Flex AIR exporter when the app is created
String path = absPath + "/MacOS/MyAirAppToLaunch";

Hope it helps
