There is no need for another starter application. Try adding the JAR
files to the ImageJ plugins directory, or sub-directory. ImageJ's
PluginClassLoader can load classes from JAR files located in the
plugins directory. If that doesn't work, try adding the JAR files to
Java extension directory, ..\ImageJ\jre\lib\ext on Windows and Linux,
or /System/Library/Java/Extensions on Mac OS X.
