I'm trying to install Java FX again from download software section in eclipse. I did the procedure multiple times but this time I'm having troubles finding a Java FX version (eclipse can't even find it in any available site).
Online or from the official site there is no trace of it..
So... it is dead?
Are there any alternatives for Java? (No swing please, it's too old)
Since Java 11, OpenJFX is decoupled from the Oracle JDK (this was already the case for OpenJDK), and needs to be installed separately on the Java level. You should not install it in Eclipse, because Eclipse is an IDE, not your Java installation.
To be clear, Java FX is not dead, the decoupling just allows releases to be developed at a separate pace and your Java installation being more modular.
How you install this depends on your operating system.
For example on Arch Linux with the OpenJDK, you install java-openjfx from the extra repository.

Nashorn JavaScript engine removed from Java 16. I am running Java application (Minecraft server) which using plugin which using Nashorn Engine to run JavaScript snippets. I recently updated my server to Java 16 and now this plugin wont load.
Plugin (https://github.com/TabooLib/TabooLib) using for example import jdk.nashorn.api.scripting.NashornScriptEngineFactory;, etc...
Is there any replacement I can install to make this plugin work again? Or I need to ask developer to deal with it in repository?
I was reading about GraalVM, but I am not sure it will work as drag-drop replacement and also I do not work to switch from OpenJDK just yet...
There's a standalone Nashorn distribution now; version 15.2 allows you to run with JDK 11 and up. See answers https://stackoverflow.com/a/66190018/252858 and https://stackoverflow.com/a/65983899/252858 for more discussion about Nashorn on JDK 15 and up, and https://github.com/szegedi/nashorn/wiki/Using-Nashorn-with-different-Java-versions for information about what happens if you use 15.2 on JDK 11-14.

I remember in the past there was an infrastructure given to the public to check the compatibility of the JVM and its libraries itself. If I am correct, that was Java Device Test Framework, which now has magically disappeared. In its place is only the Java Device Test Suite, which is actually only for ME edition (and commercial) or Java Compatibility Kit, which again is not open source & publicly available.
What I'd like to accomplish is to use these tests myself on other non "full JDK" JVMs, like Avian, MobiVM, CrossMobile or TotalCross, in order to have a rough estimation of what is missing and what to expect.
Definately I don't need to check the full JDK -- that would be out of concept. What I am more interested is more base functionality, i.e. things that one could find on the java.base (at most). So, is there any (preferably) open source toolkit available?

So this is a complete newb question. I have learnt a bit of java and am moving on to Spring. Could I do all my development on Digital Ocean instead of setting up an IDE like eclipse on my laptop? I have created an Ubuntu droplet on Digital Ocean. I am sure i can run some sudo commands to install eclipse. How would I run a graphical IDE though? I wouldnt be able to do that through putty.
Does it make sense to try what I am saying or am I completely on the wrong track?
I think you may be a bit confused here.
DigitalOcean is a provider for virtual machines on which you can run your application on. These remote servers are usually not suitable to develop software.
Normally you want to develop you application with an IDE you have installed locally and then run the finished, tested and compiled version in your production environment on the server.

I have exist weblogic and JDK old versions on Windows platform. I want to update them. But when I search document about update steps on internet, I couldn't find anything. They just mention about installing process.(I know how to installing on systems but I don't want to delete and re-install).
So I really want to see step by step updates. Anyone can share doc or link about it?
7 STEPS as below to do upgrade weblogic 1036 from JDK6 to JDK7
Install JDK 7;
Stop all processes that use the your MW_HOME.
Edit $MW_HOME/wlserver_10.3/common/bin/commEnv.sh and change the JAVA_HOME location.
For every domain, change the domain "setDomainEnv.sh" script to accomodate for the net JAVA_HOME .
Change the JDK location specified in nodemanager.properties for the default and any other existing nodemanager process
Replace the new JDK location on all the minor tools used in the same MW_HOME, such as BSU, uninstaller, etc.
Restart the processes as normal, they should take the new JDK version.
Please refer to this for more details.

I just finished writing a Java program that has some tools for debugging and working with Android phones. The program itself executes ADB and FASTBOOT commands from the Android SDK.
Is there an easy way to create some kind of installer that will install my Java program as well as check/install ADB and FASTBOOT?
(I know creating an installer defeats the purpose of Java, but I know this software will only be run on Windows machines)
I think the freeware version of Advanced Installer should have everything you need.

You can make an executable version of your Java program using RCP.
Since ADB and Fastboot are just small executables you could include them with your project rather than depending on a separate install.
