Installing Capella vs Capella Studio and the need for JMV

KaBe · 10 November 2022 17:38

Hello,
I noticed 2 things:

Older versions of Capella Needed Java installations, whereas newer version of Capella had “their java” within the installation, or something like that? I might be wrong.
Capella Studio, on the other hand, ALWAYS needed a java installation!

I was using a computer that had no possibility to upgrade Java or Java Virtual Machine (JMV) and I noticed that:

Capella V6: worked fine!
Capella Studio v6: It needs a java update! (or JMV update)

Isn’t it possible to release versions of Capella Studio that do not need JMV upgrades? Having their “own JMV” sort of thing?
Thus, making it easy to “develop” with CS, in any environment.

Hi,
Yes indeed, capella embeds now its own java.

Not perfect solution, but if you have installed both capella and capella studio, you can edit eclipse.ini of the capella studio installation to refer to the java of capella installation

something like : (relative or absolute path to the jre/bin)

-vm
..\capella-6.0\capella\jre\bin

at the top of the capella studio eclipse.ini

= Prerequisites =

For a successful installation of Capella, your computer must meet the following recommended requirements:

*  64 bit computer with Windows, Linux or Mac Operating System. (Linux and Mac have not yet been field-proven tested).
*  An unzip software such as 7-Zip or equivalent
*  2 GHz processor
*  4 Go RAM
*  15 GB of available hard disk space

'''Note:''' If you intend to install a previous Capella release, follow installation instructions below but please consult the [[#Previous releases installation]] as there are some slight differences on previous Capella releases

== Java Runtime Environment ==

Starting from Capella 6.0, a JDK [https://adoptium.net Temurin (from adoptium.net)] is directly embedded in the product. Having an additional Java environment on your machine is no longer a requirement.

'''Note:''' This distribution is a production-ready open-source build without legal requirement to subscribe to a commercial support contract and distributed under [https://openjdk.java.net/legal/gplv2+ce.html GNU General Public License, version 2, with the Classpath Exception].

'''Note:''' Notice that only the embedded JDK has been field-tested.

It worked!
But you have to put the “-vr” before “-vmargs” in order for it to work.
Great
