title: How to run Java based .app without JAVA / JRE
body: <p>We have deployed a Java based application for MacOS and Windows. We have now the issue that some users don't have Java installed and seem to be unable to figure out the error message and install Java on their own. This is only the problem for MacOS users, as we used Lauch4J for Windows, which redirects directly to Oracle in case Java is not yet installed. Is there any possibility to do this also for MacOS?
  The alternative would be to ship the application directly with JRE or make it runnable without JRE at all. What are the alternatives and which is the easiest?
  Thanks in advance!</p>
