ImageJ with OpenJDK with Windows 7/10

[Philipp Schneider]

Hi there,

in our company we use ImageJ quite a while - but cause of the new restriction using oracle Java we try to use imageJ with OpenJDK and Windows as Operating System. At home I use Ubuntu Linux with OpenJDK and ImageJ - but it seems to be different with Windows.

Is there a useful possibility with ImageJ and OpenJDK using Windows 7 or 10?

Thanks in advance

I believe ImageJ 1.x [1] should work with OpenJDK 11 on Windows.
ImageJ2 [2] (and therefore Fiji [3]) currently has issues with OpenJDK 11,
but does work well with OpenJDK 8. Unfortunately, to my knowledge, there is
no OpenJDK 8 build available for WIndows (https://jdk.java.net/8/ only has
Oracle Java builds).

More information about what you want to do, and what is not working for
you, would be helpful:

* What did you try -- and do you receive an error message?
* Which version of OpenJDK do you want to use? 8? 11?
* Which version of ImageJ do you want? ImageJ 1.x? Or ImageJ2 via Fiji?

Regards,
Curtis

As I know (and understand)
even the use of JRE could cost money when used in commercial environment
and Oracles new license model will be active.
So we try to use openJDK using ImageJ.

Can you please cite a source? I have not seen anything to that effect. Only
the fact that Oracle charges a license fee for "commercial features" (none
of which ImageJ uses) of their distribution of the JDK.

Regardless, I agree that using OpenJDK for ImageJ is certainly the best way
to go.

P.S. Regarding OpenJDK 8 builds for Windows: I forgot about at least two of
them:
- JetBrains: https://github.com/JetBrains/jdk8u
- Zulu: https://www.azul.com/downloads/zulu/

And you can also get openjdk 8 via conda:
https://anaconda.org/anaconda/openjdk

Hi Curtis,

> I believe ImageJ 1.x [1] should work with OpenJDK 11 on Windows.

We currently use ImageJ 1.52h with self-written scripts (that's why we want to keep it :-)) and tried OpenJDK 11.
We don't use clean Java, but JRE - guess I need to find out
the version here

I am not that firm in switching between Java Versions (Oracle and OpenJDK) using Windows - its better documented using Linux.
ImageJ for Windows always comes with build-in JRE - just deleting the JRE Folder and installing OpenJDK hoping it will work or I just need to configure the "Java Path" did not lead to success. How can I teach ImageJ to use OpenJDK in the windows world?
Is there any idea or experience to use ImageJ with OpenJDK and Windows?

Hi,

its just a german source but a good one - one of the most famous IT magazines:

https://www.heise.de/developer/artikel/Wird-Java-jetzt-kostenpflichtig-4144533.html

You can use: https://www.deepl.com/translator
for getting the stuff into 'good' English.

"Verschärfend kommen wichtige Änderungen hinzu, die den Einsatz des Oracle JDK beziehungsweise des Oracle JRE in Produktion betreffen: Ab Java 11 sind beide nur noch in Entwicklungs- und Testumgebungen kostenfrei nutzbar. Zwingende Voraussetzung für den Einsatz der Oracle JRE in Produktion ist der Abschluss eines kommerziellen Supportvertrags bei Oracle. "

-->

"Important changes are also aggravating which concern the use of the Oracle JDK or the Oracle JRE in production: As of Java 11, both can only be used free of charge in development and test environments. The conclusion of a commercial support contract with Oracle is a mandatory prerequisite for the use of the Oracle JRE in production."

Is there any way to download Imagej for Windows without any Java and
configure Imagej in that way it can use OpenJDK? Which config files have
to be edit to do so?

Hi Philipp,

for plain ImageJ under Windows, you can edit the ImageJ.cfg file to give
the path to the javaw.exe of your desired Java installation:

     .
     C:\path\to\your\jre\bin\javaw.exe
     -Xmx1500m -cp ij.jar ij.ImageJ

where '-Xmx1500m' means 'use 1500 MB memory'.
(You can change the memory settings later in
Edit>Options>Memory&Threads, then restart ImageJ)

You can see which Java Runtime Environment (jre) you are using with
Plugins>Utilities>ImageJ Properties in the line 'java.home:'

In case there is no ImageJ.cfg file and no jre folder in the ImageJ
directory, the ImageJ Launcher will try to find the default Java
installation and create a ImageJ.cfg file for it.

Hi Michael,

took a while for testing - but it works - thanks a lot.

Ciao und schöne Weihnachten :-)
