Thanks! I noticed that NullPointerException, and it made me wonder if the problem’s similar to what I was experiencing when trying to get the CF11 Server to run - i.e., that it’s expecting a .jar file that no longer exists in the JDK.
After reading the SO post, and considering the success I’ve had connecting with newer versions of CF, it makes me wonder if the problem isn’t that the CF11 Admin is expecting an older version of the MySQL Driver than I have, especially since I had to set the Java version to “openjdk8” in server.json. In which case, I’d think getting the latest MySQL driver (8.0.33) won’t help. Is there a way to check what version of the MySQL driver I currently have, and might there be another setting I should put in my server.json file?
Thanks - I’m trying to think this through on my own steam, but the way forward isn’t clear yet…
P.S. - Just found the answer to my first question, after looking at “Downgrade mysql-connector-java - #2 by bdw429s”. Looking in cfusion/lib for that CF11 server, I see the MySQL connector I have is mysql-connector-java-commercial-5.1.25-bin.jar. Still unsure how to proceed though - do I want to replace that with a different driver?)
