Question iPOJO

Hello , 

 

I want to know how assign a property to
service in iPOJO ?

I know that in OSGI for
example:

  Properties props = new Properties();

  props.put("Language",
"English");

  context.registerService(DictionaryService.class.getName(),
new DictionaryImpl(), props);

 

And how search a reference of
service using this property?



Thank you for answering me.

Best regards,

It is part of the compendium spec, not the core spec...it will actually 
be moved to the core spec in the next release.

Am asking because I can't seem to find ServiceTracker in R4r3 javadoc.

No. Most people should completely ignore anything to do with any hooks 
in OSGi...

Best to use a component framework like DS or iPOJO.

It worth noticing that the example you are providing is not iPOJO
related it's plain OSGi.

To answer your question:
First you need a ServiceReference you can get it using where you give
a filter with the required service parameters:
http://www.osgi.org/javadoc/r4v43/org/osgi/framework/BundleContext.html#getServiceReferences(java.lang.Class,
java.lang.String)

then you get your service using:
http://www.osgi.org/javadoc/r4v43/org/osgi/framework/BundleContext.html#getService(org.osgi.framework.ServiceReference)

However this is not considered robust coding practice in OSGi world,
you'd better look into ServiceTracker and whiteboard pattern

Guys isn't that called Hooks in R4r3?
