Non operative JDK 10

[markh2016]

Will you be making the corrective adjustments in line with the new JDK ? This is non operative with JDK 8 or 9 , or 10 Many of the jar files have been discontinued or ar no longer available for download Oracles new policies have discarded many of the jar files now needed for this to compile and run

Probably not, since this project is discontinued. I keep it online for the public, because there are many requests for that.

That's a bloody good program you've written I managed to get this all up and running eventually but had to use jdk8 instead of nine I still use it You should continue with this I was very impressed with this

Just in case someone else comes here looking for a solution, this is what worked for me on a Windows 10 machine:

• Download and install a working version of the Java 7 JRE.
• Modify Win_Start.bat in the BlackBoard folder to use the Java 7 java.exe, e.g. (in my case);
  "C:\Program Files\Java\jre7\bin\java" -jar BlackBoard.jar
• Use Win_Start.bat rather than BlackBoard.exe to start BlackBoard.

I successfully got it running on OpenJDK 17. Hope my PRs get merged, then up to date builds could be provided automatically by Github. This is indeed a really good application. I am impressed.

I can't get it running on OpenJDK17. But i can't see any related PRs either.

[HiranChaudhuri]

Since I saw this repo is more in archived state I removed my fork. That's likely where the PRs vanished.

[klauweg]

Ok, i see. It's really a pitty that this project isn't maintained any more.
But at least i found another fork which makes blackboard useable again with OpenJDK17:
https://github.com/oflebbe/blackboard

I got it not running either in Linux Mint with OpenJDK21. Installation procedure itself was successful. Starting the app I get the splash screen but without loading modules - so it is stucked at this stage. The fork does not work either. Any hints?
