Also, I already know my apps work under Java 1.7 on Windows, I was referring to the fact that the Oracle site says that drag and drop is not yet implemented in Java 1.7 on the Mac port which is in progress.

Duplicate the project file, add your JARs and resources, and build.

Not to completely crowd-source this, anyone has step-by-step instructions for how to build the new JavaAppLauncher and repackage your app, please put them here: <https://wikis.oracle.com/display/OpenJDK/How+to+embed+a+.jre+bundle+in+your+Mac+app>.

Also, this discussion is more appropriate on the macosx-port-dev at openjdk.java.net list, since it is an OpenJDK technology, and more Oracle people are on that who can help.
