Missing javax.inject when trying to run a javaFX application

Question

I got the following stacktrace when trying to run my javaFX application, how to fix this? What is actually causing the problem? I haven't removed anything other than an old dataFX lib. I am using eclipse with the latest version of java, and the javaFX plugin.

Exception running application application.MainApp

Answer 1

javax.inject is a JavaEE framework, it is not included in a JavaSE 8 distribution. You will need an additional library bundled with your project which includes a javax.inject implementation. I believe afterburner.fx is an example of a thin framework for JavaFX which includes a javax.inject implementation.
