Fixing Runtime Components in the short term
But, I completely understand if you just need those fixes, you can skip ahead to there too. I’ll talk a little about why this is happening, because it has to do with JavaFX’s custom windowing and rendering systems. If you’ve got a Jar that won’t run, feel free to skip on down. I’ll start with launching from the IDE, because that seems natural. The solutions in each case can be similar, although if you can’t make your app modular you will have to apply command-line arguments both in the IDE and with your Jar. It won’t run, but you’re smart enough to run it from the command line. You’ve got a JavaFX application packaged as a jar.You’re in an IDE and when you hit ‘Run’ the IDE delivers the error.Generally, there are two situations you could be in to find this error. The good news is there are several easy ways to fix your app. So if you’ve had this error don’t be disheartened. When I first came back to JavaFX after using it in Java 8, every single one of my old prototypes crashed. However, it can be corrected by adding JavaFX modules, using command line arguments.
It is generated for all non-modular JavaFX projects since Java SE 9. But this is one of the few awkward stumbling blocks that trips a lot of people up.Ī “Runtime Components are Missing” error is generated by the Java Launcher. Honestly, JavaFX should be a very intuitive and easy to use piece of software. One side effect of Oracle removing JavaFX from the JDK was to make it harder to get started. Even if you consider yourself to be pretty Java-savvy. It can be a huge frustration if you’re trying to get into JavaFX. Import you’re not familiar with Java modules, you’re almost guaranteed to get hit with an error: “Runtime Components Are Missing”. It simply give you a taste of machine learning in Java.ĭownload stable.XX.zip, unzip the file, add weka.jar to your library path of Java project in Eclipse.Ĭreate a txt file "weather.txt" by following the following format: outlook This is a "Hello World" example of machine learning in Java.
