Hello,

 

I have multiples OSGi bundles that use the same configuration properties.  Now I create a below service for each bundle:

@ObjectClassDefinition(name = "My configuration service", description = "Configuration for bundle")
public @interface MyConfig {
           @AttributeDefinition(name = "My API:", description = "API endpoint for project", type = AttributeType.STRING)
           String myPropAPI() default "....";
...
}
@activate
protected void activate(final MyConfig config) {
         this.api_endpoint = this.config.myPropAPI();
}

 

Is it possible for other bundles to share this configuration service? Or  should I create a property file accessed directly by all bundles?  

 

Thanks for any input

You can try to create a factory configuration.

 

OSGi provides a way to configure services and modify those configurations on the run-time. But apart from this there is a another powerful feature that OSGi provides that is : ability to create Factory Configurations. Factory Configurations is a way to create a single service, and bind multiple configurations to it  & then consume those configurations from different classes/Services.
