Mac Java Application Resource Path

Question

Using the appbundler ant task from oracle ( http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/packagingAppsForMac.html ) I can create a working Mac application with JRE7 enabled, but loading some resources like native libraries failed because the path at the seams of Info.plist is invalid.

In the build.xml ant task that I use, for example (my own libraries are copied to the Content / Java folder inside the application package):

a) <option value="-Djava.library.path=Contents/Java/" /> b) <option value="-Djava.library.path=$JAVAROOT/" /> c) <option value="-Djava.library.path=$APP_PACKAGE/Contents/Java/" /> 

All results in UnsatisfiedLinkError. No other resources were found, such as splash-image:

 <option value="-splash:Contents/Java/my-splash.png" /> 

Any idea how to set the path for JVMOptions correctly here?

Edit: The Java7 appbundler application does not use the same plist syntax as Apple's Jar Bundler, which comes with jdk6, for example. there is no “Java” to add SplashFile.

According to the appbundler task documentation, the magic variable you are looking for is $APP_ROOT :

 <option value="-Djava.library.path=$APP_ROOT/Contents/Java/" /> 

This also works for <argument value="..."/> (arguments for your main class, as opposed to JVM parameters).
