Hi Jacques,
we are using Ubuntu for all our servers and I cannot confirm that.
update-alternatives is used to generally set the envoronment to a
specific JDK through JAVA_HOME. You can still set and thus override this
environment variable in the shell session for the demo user.
On our developer machines (Mac OS/Unix based) we use simple aliases to
change the JAVA_HOME variable to the needed JDK and can change fluently
between them.
sudo is not required for this.
Regards,
Michael

Hi,
I got it to work, as often this was not as simple as expected, long
story as short as possible.
It was not possible to set java env vars (JAVA_HOME and PATH). Because
The VM uses "Ubuntu 20.04.5 LTS".
Ubuntu by default uses update-java-alternatives to handle Java
versions. We had only JDK 11 so far, it's easy to add JDK 17 with
"alternatives".
Update-alternatives uses symlink to handle env vars. So setting java
env vars in scripts (or even in terminal) simply does not work.
So I thought that by using something like*
|update-java-alternatives -s java-versionexport
JAVA_HOME=/usr/lib/jvm/|||java-version|/||export PATH=$PATH:$JAVA_HOME|
||
in scripts it would be easy to set the necessary versions.
But update-java-alternatives requires to use sudo.
And, for security reason, all demo scripts must be run with ofbizDemo
user.
Again for security reason, ofbizDemo is not a sudoer.
So update-java-alternatives was not an option.
I did not know anything about "SDKMAN!"** but it seemed to be a solution.
Again, not as simple as expected. SDKMAN uses BASH to set env vars and
Ubuntu uses DASH behind "sh".
So few adjustments were necessary. You can see them at***

Enjoy!

Hi Michael,
I'm sorry, somehow I missed your email. I can't give you access,
that's Infra's privilege.
We recently had a discussion with Daniel on Slack OFBiz channel about
that, here is the relevant part copy
<<To get SSH access to the demos VM just
followhttps://infra.apache.org/vm-for-project.html#ssh-keys
<https://infra.apache.org/vm-for-project.html#ssh-keys>
You need also to ask Infra for being a sudoer as explained
athttps://infra.apache.org/vm-management.html
<https://infra.apache.org/vm-management.html>So first you need to ask
the PMC>>
As your are a PMC, I think you don't need need to ask the PMC.
I thought that setting different JAVA_HOME environment variable
values in one of the scripts would have undesirable side effects on
the other scripts.
Anyway let me try your trick as it seems indeed easy.

Hi Jacques,
I have no access to the server right now so I cannot see where the
Java installations reside or which Linux distro we use.
Can you give me access, preferably per ssh/public key to the machine?
On Ubuntu and Mac, you just install the different JDK's beside each
other and point to the JDK which should be used by setting the
JAVA_HOME environment variable in the start script. Easy.

set JAVA_HOME to the right JDK in the OFBiz start/stop scripts
Hi Michael,
That's a good news, how would you do that? A patch at
https://github.com/apache/ofbiz-tools/tree/master/demo-backup would
be welcome
Thanks
Jacques
