Re: [equinox-dev] Issue with Felix SCR and Dependency manager Annotation

[Mark Hoffmann <m.hoffmann@xxxxxxxxxxxxxxxxxx>]

Hi,

you should try to annotate you SCR Components using the OSGi annotations:

- org.osgi.service.component.annotations.Component

- org.osgi.service.component.annotations.Activate

- org.osgi.service.component.annotations.Deactivate

and so on.

But remember that these annotations are build time annotations, So you need tools like bndtools or the PDE (PDE only support DS until 1.3) that generate the metadata (componenten - xml files) for these annotations.

Felic SCR is the implementation for OSGi Declarative Services:

It is the implementation for OSGi Declarative Services:

https://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.component.html

https://developer.ibm.com/articles/osgi-demystified-part-5-using-declarative-services/

I hope this helps.

Regards,

Mark

Hi All,

I am working on an OSGI project where I am upgrading jetty and OSGI versions from R-4.9 to R4_19_maintenance and Jetty version is getting upgraded from 9.4.11 to 9.4.44

I was using org.eclipse.equinox.ds(1.4.400) as a bundle earlier which was using org.apache.felix internally.

Since org.eclipse.equinox.ds dependency has been removed from R4_19_maintenance,

I have added dependency of org.apache.felix.scr(2.1.24) but the issue is org.apache.felix.scr.annotation services are not getting activated.  (Activate method is not being called)

Also,  the same is happening with  org.apache.felix.scr.dependencymanager.annotations (3.2.0) and the services are not getting started (Start method is not being called)

Can you please help me in knowing if it is the version of org.apache.felix.scr.annotation that is causing the issue, if yes, which version it supports or what could be the possible issues that might be causing this.

I appreciate your quick response and thanks in advance.

Thanks,
