Zulu openJDK

[nodiaque]

Hello everyone,

I'm trying to do something that should be simple but is not. Installing Zulu openJDK. I followed part of the instruction on there website, starting with downloading the jdk here:
https://www.azul.com/downloads/zulu-com ... ackage=jdk

extract the tar and move the content to /opt/zulu11. Then, I create a symbolic link in /usr/lib/jvm that point to it.

This is working great, I now see both my old and new jvm in eselect

Code: Select all

eselect java-vm list
Available Java Virtual Machines:
grep: /usr/share/java-config-2/vm/zulu-jdk-11.0.9.1: No such file or directory
  [1]   oracle-jdk-bin-1.8
  [2]   zulu-jdk-11.0.9.1  system-vm

But once I set system to zulu-jdk and I try to run java, I get this message:

Code: Select all

java
* java is not available for zulu-jdk-11.0.9.1 on x86_64
* IMPORTANT: some Java tools are not available on some VMs on some architectures

What I don't get it is why I have this message. java is present in the same path, either ./bin or ./jre/bin and if I put full path to /opt/zulu11/bin/java, it work.

Thank you!

it seems all I had to do is to create a file under /usr/share/java-config2/vm with the same name and put the path and everything in it like oracle (I simply copied and paste back). wonder if there's a way to generate this file instead

This file is created in ebuild you can see skel in /var/db/repos/gentoo/dev-java/openjdk/files/openjdk-11.env.sh, in my system for openjdk-11 file become

problem is it wasn't an ebuild, just a tar.gz I unzipped and extract to a folder, ready to use.

[fedeliallalinea]

I know but you can try to create file manually, like openjdk example I posted, and put it in /usr/share/java-config-2/vm/

[nodiaque]

oh yeah, that's what I did and it solved it. Just unsure if all I put in it is ok but seems to be running fine.

Thanks!

i'm running into a similar problem... i downloaded the tar file, and placed in /opt/ and made a link w/ friendlier name:

and i created /usr/share/java-config-2/vm/zulujdk-bin-18.0.2:

but when i list using eselect, i get:

Code: Select all

  [1]   openjdk-bin-17  system-vm
  [2]   zulu-jdk-18.0.2

[root /opt %]

which confuses me, because 1) /usr/share/java-config-2/vm/zulu-jdk-18.0.2 shouldn't be a directory anyway, right? and 2) i set up the zulu config file to mirror the openjdk file...

what did i do incorrectly?

needless to say, if i set it to (2) and run java, i get an error:

Code: Select all

[root /opt %] eselect java-vm set 2
[root /opt %] java
* java is not available for zulu-jdk-18.0.2 on x86_64
* IMPORTANT: some Java tools are not available on some VMs or some architectures
[root /opt %]

so clearly something is broken...

thanks!

just bumping to the top...

need to get zulu running to use TD Ameritrade's ToS application. thanks for any help!

Does it work without using Gentoo VM configuration? Like

Code: Select all

export JAVA_HOME="/your/path/to/zulu-jdk/"
export PATH=$JAVA_HOME/bin:$PATH
java -version

i use thinkorswim and i love the customization of gentoo. after thinkorswim upgraded to java 11 from java 8, i didn't know how to get it to work until i came across an ubuntu solution:

download TOS recommended Java Zulu 11 from their official website:
http://www.azul.com/downloads

unzip the download to home folder:
tar -xzvf zuluPackage.tar.gz

verify it is working:
/home/user/installation_folder/bin/java -version

i made a custom script similar to the ubuntu solution:
#!/bin/bash
export PATH=/home/user/zulu11.60.19-ca-jdk11.0.17-linux_x64/bin/:$PATH
/home/user/thinkorswim/thinkorswim

and got it working! i tried emerging openjdk ver 11 but that did not work for me. thinkorswim complained that there was not enough memory.
hopefully this helps others
