[news.eclipse.platform] how to read the extensions registry outside ecli

["Rashmy" <appanera@xxxxxxx>]

Hi,
I have to write a utility that can be run from command line to read all 
extension contributions to an extension point. I have looked into headless 
RCP and OSGI launchers. All these require eclipse.core.runtime plugin. I 
cannot be dependent on core.runtime since we are running our utils on 
HP-Itanium. Hence I have to write a Java utility class that can read through 
all my jar files (plug-ins) and figure out the extension contributions in 
all plugin.xml files and load these classes. Can you point me to the eclipse 
code that creates and loads the extension contributions to the Eclipse 
registry? Is there some sample code that I can take a look at to read all 
plugin.xml files from all jars and create my own registry?

I have many extension points. Is it worthy to convert all these into 
Declarative Services and create an OSGI application?

Thanks,
Rashmy
