i am having issues launching designer from the gateway for ignition 7.9, it is running on a linux ubuntu 24.04 PC, are there instructions on the manual or somewhere on how to do that. the ignition installation was fine
Issue i am having is a compatibility mismatch, when ever we try downloading icedtea it does a reinstallation of java 21 and produces an error message of compatibility mismatch even though I have java 8 installed and have made it the default. I need to figure out why that is happening and why its not launching, I was hoping there is an ignition installation and designer launch manual for linux.
You should upgrade to the latest 7.9.x and use its designer launcher with its packaged java.
Phil's suggestion is certainly the easiest and recommended approach.
If you must, then perhaps try removing JDK 21 and the icedtea package that you installed from your package manager.
Instead, install JDK 8, preferably AdoptOpenJDK 8, and then try manually downloading and installing IcedTea from here: IcedTea-Web | AdoptOpenJDK - Open source, prebuilt OpenJDK binaries
I have removed JDK 21 several times and the icedtea package, forced javaws to use Java 8 and reinstalled the icedtea package but it continues to fail the launch and generates a package mismatch error even through its is forced to select java 8 and does an auto install of java 21. I will try to install the latest version of 7.9 and see if that solves the issue and as Kevin mentioned it might be the specific IcedTea package installed that is causing the issue.
It's coming back because the icedtea packaged for Ubuntu 24 depends on the default-jre package, which is JDK 21.
Your screenshot shows usage of JNLP, from launching from a link on the gateway instead of using the designer launcher.
JNLP was removed from java for security reasons, and should not be used, and cannot be used in modern java.
IIRC, Ignition v7.9.10 was the first to include a designer launcher. That does not require JNLP. Try it.
how do i get native designer launcher to run, is there something on that gateway webpage the does that or a link i have to use
You download it from the gateway webpage, it should be a .sh file for the Linux version.
Execute it from a terminal.

i wanted to project designer to launch not the client view, i was not able to get the designer launcher to work
Why?
(Help us help you, by posting all possibly relevant messages and errors from any terminal sessions.)
i will provide screen grabs, it takes me to this page when trying to get desginer launcher to run even though version 7.9.19 is installed
You don't run the designer launcher from a URL in the browser. You run the launcher script after downloading and expanding the launcher package from the gateway.
You add the target gateway to the local launcher's configuration, then use the open designer button in the launcher UI. Not in a browser.
(It is a single launcher package in v7.9. In v8+, client and designer have separate launchers.)
Thank you for the help. I was able to download native client launcher and open the designer from there. Worked fine.
