安装jdk 7u9后无法识别javafx

Question

I installed jdk 7u9 and added it to the build path of an eclipse Java project. However, when I'm trying to import some javafx classes eclipse can't recognize them:

       import javafx.scene.media.Media;

I read at Oracle's website (and a lot of other websites) that javafx is already included in jdk 7u9 and there is no need to install any additional addons.

What could be the problem?

Answer 1

The jfxrt.jar is in the jre/lib folder of your jdk, but not on the default boot classpath. That is why Eclipse won't add it to the "JRE System libraries".

The issue is tracked here . The fix will be made in Java 8.

You should add the jar manually to the project build path or use e(fx)clipse and setup a JavaFX Project.
