JavaFX is not recognized in Eclipse

JavaFX is supposed to be included with the latest release of the JDK. I'm using 1.7 v 17. Imports like:

import javafx.fxml.Initializable;

are not recognized. I would prefer not to have to link to the jar manually.

I heard that this was a bug before, but that it should have been fixed. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7166330

Does anyone have an answer on how javafx can be recognized. I don't want to have e(fx)clipe do it for me and I don't want to have to link the jar. As far as I understand, it;s now included in the latest release of the jdk, therefor I should be able to do an import like above right?

Solution 1:

JavaFX isn't on any of the default classpaths in JDK7 - please see in which version the bug has been fixed!

In JDK8 this is fixed and JavaFX is on the ExtensionClasspath but still you'll get warnings from Eclipse because stuff on the extension classpath is considered an implementation detail - you'll can fix this yourself in the JRE-Runtimes.

What's your problem with e(fx)clipse? It would fix all your problems no matter if you develop against JDK7 or JDK8?

Solution 2:

On Ubuntu 14.10 I had to install first openjfx

sudo apt-get install openjfx

then I created a default project using e(fx)clipse and the default JRE (java-8-openjdk-amd64).

Solution 3:

You can add the "jfxrt.jar" manually! Its in the installed JDK. Example:

• Windows XP: "C: \ Program Files \ Java \ jdk1.7.0_17 \ jre \ lib \ jfxrt.jar"
• Windows 7 (32 bit): "C: \ Program Files (x86) \ Java \ jdk1.7.0_17 \ jre \ lib \ jfxrt.jar"
• Windows 7 (64 bit): "C: \ Program Files \ Java \ jdk1.7.0_17 \ jre \ lib \ jfxrt.jar"

Copy the jar file and put it to a subfolder in the project (for example, / lib).

Now add the "jfxrt.jar" to the classpath. Click the right mouse button on the project and select from Properties -> Java Build Path -> Libraries -> Add JARs from ... and add the jar file.
