在Windows上使用OpenJDK运行JabRef

Question

although I'm just trying to install JabRef, I am quite surprised that this seemingly easy task is giving me so much trouble.

I am using Windows 10 and I want to use JabRef (the most current version, which is 4.3.1). I do not have the JRE oder JDK for Java 8, but I have the Oracle Java 12 JDK. JabRef requires a JDK 8 but I cannot download it from Oracle without login. (And since they are quite nosy, I refuse to sign up to get the download.)

So, I tried to use OpenJDK but that does not come with JavaFX, which JabRef requires. I also downloaded OpenJFX but now I am puzzled how to put everything together. OpenJFX is not "installed", so JabRef still complains that there is no JavaFX:

So, my question is:

• How can I define where my OpenJFX is?, or
• Where can I get a JDK or JRE that contains JavaFX for Java 8?

Best regards!

Answer 1

OK, I found a solution that worked for me. I simply used a JDK for Java 8 that includes Java FX: ZuluFX .

I unstalled JabRef and reinstalled it. I was prompted to say where my JRE ist when I reinstalled it. After that, it seems to work fine.
