What version of Java do I require?
I got a noClassDefFoundError
The windows version ships with it's own installer which bundles the latest version of java and will work simply. If you are on linux/mac or want to use your own java first check your version like so:
This error is occurs when you try to run JPad with a JRE or possibly an older version of the SDK. If you are on windows the easiest solution is to download the installer.
If you are on Linux or Running OpenJDK
JPad relies on javafx for displaying HTML results. Not all versions on the JVM, particularly OpenJDK ship with these libraries.
Check your repos for a javaFX/JFX package in themand install it. Then try to run jpad again.
