Calling .jar in theia extension

[glsp-bot]

I'm currently developing a theia extension and need to call a .jar file.
I oriented myself on how the EcoreFileGenServer works in ecore-glsp.
There is is done by injecting the processFactory
@inject(RawProcessFactory) protected readonly processFactory: RawProcessFactory,

When I try to do the same I get a lot of inconclusive errors when calling yarn.
This is probably because it will only work on the server side and not on the client side.

The question now is how I can realize this in my extension?

Hi @leo-knoll(leo-knoll) ,
you can't call a jar or any file from the frontend/client. This always needs to be done from the backend/node part of theia.
You can find an example on how to provide a custom theia extension with a backend here: https://github.com/eclipsesource/eclipse-theia-examples

@eneufeld(eneufeld) thank you for the answer, the backend-example actually helped a lot how to set up a backend and how the communication with the frontend works :)
