BackendApp error at Run OSGi

Hello!
I got this error when I try to run the BackEnd app in Eclipse (“Run OSGi”).

Hi @gyukov,

this might be an issue with the Java version you are using to run OpenEMS. OpenEMS is still using version Java version 8, and it seems that javax.xml.bind was dropped in more recent versions. I found this on Stackoverflow:

Could it be, that you are running it with Java 11?

For a OpenEMS Edge-Backend-UI setup that “just works”, I can also recommend our gitpod setup:
