在Windows上使用OpenJDK运行JabRef [英] Running JabRef on Windows with OpenJDK

问题描述

尽管我只是在尝试安装JabRef，但令我感到惊讶的是，这个看似简单的任务给我带来了很多麻烦.

我正在使用Windows 10，并且想使用JabRef(最新版本为4.3.1).我没有Java 8的JRE oder JDK，但是我有Oracle Java 12 JDK.JabRef需要JDK 8，但是如果没有登录我就无法从Oracle下载它.(而且由于他们很管闲，所以我拒绝注册以获得下载.)

因此，我尝试使用OpenJDK，但是JabRef要求JavaFX不附带.我还下载了OpenJFX，但现在我很困惑如何将所有内容放在一起.OpenJFX未安装"，因此JabRef仍然抱怨没有JavaFX:

  java.lang.NoClassDefFoundError:javafx/application/Application在java.lang.ClassLoader.defineClass1(本机方法)在java.lang.ClassLoader.defineClass(ClassLoader.java:763)在java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)在java.net.URLClassLoader.defineClass(URLClassLoader.java:468)在java.net.URLClassLoader.access $ 100(URLClassLoader.java:74)在java.net.URLClassLoader $ 1.run(URLClassLoader.java:369)在java.net.URLClassLoader $ 1.run(URLClassLoader.java:363)在java.security.AccessController.doPrivileged(本机方法)在java.net.URLClassLoader.findClass(URLClassLoader.java:362)在java.lang.ClassLoader.loadClass(ClassLoader.java:424)在sun.misc.Launcher $ AppClassLoader.loadClass(Launcher.java:349)在java.lang.ClassLoader.loadClass(ClassLoader.java:357)在com.exe4j.runtime.LauncherEngine.launch(LauncherEngine.java:81)在com.exe4j.runtime.WinLauncher.main(WinLauncher.java:94)在com.install4j.runtime.launcher.WinLauncher.main(WinLauncher.java:25)引起原因:java.lang.ClassNotFoundException:javafx.application.Application在java.net.URLClassLoader.findClass(URLClassLoader.java:382)在java.lang.ClassLoader.loadClass(ClassLoader.java:424)在sun.misc.Launcher $ AppClassLoader.loadClass(Launcher.java:349)在java.lang.ClassLoader.loadClass(ClassLoader.java:357)...另外15个 

所以，我的问题是:

• 如何定义OpenJFX的位置?或
• 在哪里可以获得包含JavaFX for Java 8的JDK或JRE?

最诚挚的问候！

解决方案

好的，我找到了适合我的解决方案.我只是使用了包含Java FX的Java 8 JDK: ZuluFX .

我取消安装JabRef，然后重新安装.当我重新安装它时，系统提示我说我的JRE文件在哪里.之后，它似乎可以正常工作.

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:

java.lang.NoClassDefFoundError: javafx/application/Application

at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
... 15 more

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!

解决方案

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.
