If you run a Java application that uses Carbon via JNI, the application is not registered with the OS as a ‘normal’ UI application. As a consequence, it has no entry in the dock and it cannot be activated. AWT (or Swing) based applications don’t have this problem because they seem to use undocumented SPI to register themselves. To work around this problem you’ll have to use the executable ‘java_swt’ that is part of the Eclipse distribution (you can find it inside the Eclipse application Eclipse.app/Contents/MacOS/java_swt). Basically it is a replacement for /usr/bin/java and the ‘JavaApplicationStub’ used in bundled applications.
