java - Multiple PIDs for one target service with ds annotations -

i'm wondering if possible leverage explaned @ par.104.7.5 (using multi-locations) of osgi enterprise specs using declarative services annotations. quoting specs:

it possible bundles interested in multiple pids 1 target service, reason can register multiple pids 1 service. [...]

a bundle interested in host configuration register managed service following properties:

service.pid = [ "com.acme.host", "com.acme.system" ] 

the bundle called both com.acme.host , com.acme.system pid , must therefore discriminate between these 2 cases. managed service therefore have callback like:

volatile url url; public void updated( dictionary d ) { if ( d.get("service.pid").equals("com.acme.host"))     this.url = new url( d.get("host")); if ( d.get("service.pid").equals("com.acme.system"))    ... } 

i tried following syntax:

@component(     immediate = true,     configurationpid = "[com.mycompany.ws.rest,com.mycompany.endpoints]",     configurationpolicy = configurationpolicy.require )  public class testimpl implements test {     // ... } 

but fails. of course 1 can reference config admin , browse configuration based on desired pids seems little bit inelegant me since in theory possible delegate ds annotations.

is possible? correct syntax?

thank you!

i don't believe possible using configurationpid , configurationpolicy values. following:

• define service factory pid(s) service property.
• implement managedservice interface.

example:

@component(property = {constants.service_pid + "=com.acme.host",                         constants.service_pid + "=com.acme.system"}) public class testcomponent implements managedservice {      @override     public void updated(dictionary<string, ?> dict) {     ...     } 

of course has disadvantage component activated if there no configuration it, can use 2 pids.
