Calling the Kura API methods? [message #1786855]

Hey,

I am experimenting with the Kura API and would like to use some of the methods within the API in the near future.

For now, I am interested in the "SystemService" as I would like to create a simple API that returns the Kura version as an example. The custom API is working, the problem is however to use the "getKuraVersion()" method that actually returns the version.

Does someone have any idea how that can be done?

Hi,
I'm sorry, but the question is not clear to me.
Could you please formalise it with an example?

Thanks
Best regards,
Matteo

I created a custom REST API that runs in Kura and I access it via

localhost:8080/services/sf/version

which currently just returns "Hello". Instead of that I want to return the currently running Kura version when someone makes a GET call. I assume that I'm am required to call the

getKuraVersion()

method from the "SystemService" class but I am not able to and I am wondering how I could get the current version?

Hi,
maybe have a look at the way we did for the existing Kura REST Apis: https://github.com/eclipse/kura/tree/develop/kura/org.eclipse.kura.rest.asset.provider
If you need to use the SystemService, you need to get the corresponding dependency, as done for example here: https://github.com/eclipse/kura/blob/develop/kura/org.eclipse.kura.rest.asset.provider/OSGI-INF/asset_rest_service.xml#L14
and then embed those references in your code: https://github.com/eclipse/kura/blob/develop/kura/org.eclipse.kura.rest.asset.provider/src/main/java/org/eclipse/kura/internal/rest/asset/AssetRestService.java#L58

Best regards,
Matteo

Hello,

I think the question pertains to how to use the Kura OSGi services. I have responded to the same question in StackOverflow [1].
