Instead of using regular factory component, I solved my problem by using
configurationFactory and ConfigurationAdmin.
I used my first example to be able to create new instance of my class from
configuration tab in felix console
@Component(configurationFactory = true, policy =
ConfigurationPolicy.REQUIRE, metatype = true, immediate = true)
And then, to create my class instance from java code (actually I want to
allow user to create an instance from RESTful interface)
I used ConfigurationAdmin class as follows in the documentation
ServiceReference reference =
bundleContext.getServiceReference(ConfigurationAdmin.class.getName());
ConfigurationAdmin configAdmin = (ConfigurationAdmin)
bundleContext.getService(reference);
Configuration config =
configAdmin.createFactoryConfiguration(LDPathSemanticIndex.class.getName(),
null);
Dictionary props = new Hashtable();
props.put("key",value");
config.update(props);
Now, i can use both felix console and my restful interface to create my
class instance.
thanks for your answer.
Best regards,
Meric
