Hello!

I habe the following java installed on my beagbebone black:
java version “1.8.0_161”
Java™ SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot™ Client VM (build 25.161-b12, mixed mode)

I programming small applications on my windows PC and there eclipse show me:
JavaSE-1.8

But when start my applications, some .jars are missing … I always need to search them int the web and add it to my application.

How can I install a full java on the beaglebone black?

Thank you!

I see JRE and JDK are way beyond 1.x.x and on 11. See here: Java - Debian Wiki

Java 1.8.x coresponds to openjdk-8, this shipped with Debian 9.x Stretch, which is really eol at this point: Debian -- Debian “stretch” Release Information …

Feel free to install: sudo apt install openjdk-8-jdk to get the full OpenJDK Development Kit…

Hello Robert!

Thank you … but is openjdk-8-jdk not the near the same as installed?
When I run the command, I get

openjdk version "1.8.0_332"
OpenJDK Runtime Environment (build 1.8.0_332-8u332-ga-1~deb9u1-b09)
OpenJDK Client VM (build 25.332-b09, mixed mode)

Or did you maybe mean a higher version like 17 or 18?

Debian traditionally ships only one version of Java per Debian release cycle…

Java “1.8” aka “8” aka openjdk-8 aka : 8u332-ga-1~deb9u1… shipped with Debian 9.x Stretch…

Java SE 11, openjdk-11, shipped with Debian 10.x : Debian -- Details of source package openjdk-11 in buster

Java SE 17 (LTS) , openjdk-17 shipps with Debian 11.x : Debian -- Details of source package openjdk-17 in bullseye

Thank you … so I can only use openjdk8, right?

Unfortunately I miss always some java classes. As example:
Caused by: java.lang.NoClassDefFoundError: javax/net/ssl/HostnameVerifier

This seems not installed on the beaglebone black.

Sorry, not sure, either bug the java maintainer at debian.org …

Or maybe transition to Java 11 in Buster…
