Ajax error while creating OpenEMS "Getting Started",

DominikDHBW · April 25, 2024, 10:28am

I’m trying to run OpenEMS and use OpenEMS getting started, but when I want to
do the first step I want to create the scheduler All Alphabetically. An Ajax error occurs. How can I fix it?

Best regards

Do you start the jar file inside an IDE? I think it is a problem with the runproperties. There you need to specify where OpenEms stores the configuration. Default is C:/openems/config and C:/openems/data. I assume you are on a linux distribution. Please update EdgeApp file to use runproperties with a path that is valid for your os.

You can also overwritte these parameter when starting the .jar file

felix.cm.dir
openems.data.dir

I hope that helps. Greetings!

Use the precompiled Version for starting purposes. Is easier to understand at first glance.

I run this JAR file in a terminal using this command as you described: java -Dfelix.cm.dir=/etc/openems.d -Dopenems.data.dir=/home/root/openems/data/ - jar openems-edge.jar
Unfortunately this gives me this error

did you maybe forget sudo?
