How to install Oracle jdk-8u333

[woodcockj]

Does anyone know how to install Oracle jdk-8u333 on Pi3 or Pi4?
I'm running the latest version of 64 bit Raspberry Pi OS on both a Pi 3B and a Pi 4.
I'm using jdk-8u333-linux-arm32-vfp-hflt.tar.gz
The installation instructions I have tried are these:

sudo tar zxvf jdk-8u333-linux-arm32-vfp-hflt.tar.gz -C /opt
sudo update-alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_333/javac 1
sudo update-alternatives --install /usr/bin/java java /opt/jdk1.8.0_333/java 1
sudo update-alternatives --config javac
sudo update-alternatives --config java

But when I execute:
java -version
javac -version

I get an error that says it can't find java or javac.

Does anyone know how to do this?

I don't know, do you need specific this version of Oracle java? There is OpenJDK 8u312 available via the utility "Add/Remove Software".

You say you are running Raspberry Pi 64 bit OS but you are installing jdk-8u333-arm32 which is for 32 bit OS.
Why are you not installing jdk-8u333-linux-aarch64.tar.gz (from https://www.oracle.com/java/technologie ... loads.html)?

Java 8 is long deprecated. Java 17, the long term support version is in the repository, just load that.

Java 8 is long deprecated.

Oracle has said Java 8 is supported indefinitely for personal usage and will have at least 18 months notice if they change their mind. The latest update was only a couple weeks ago.

Java 17, the long term support version is in the repository, just load that.

Some stuff is only compatible with Java 8. I've got a few "enterprise" tools that require it which means keeping a VM around just to run them. It is annoying.

The arm32 version won't run on Raspi OS 64. Download the aarch64 version and try that.

Does the software you are trying to run refuse to run under a later version? One of Java's features is that software created for an earlier version will still run on a later one.
