Have you tried using a ServiceTracker with a filter?
private <T> T getService(Class<T> type, String key, String value)
{
String filterString = "(&(objectclass="+type.getName()+")
("+key+"="+value+"))";
logger.info("Looking up services: " + filterString);
Filter filter = bundleContext.createFilter(filterString);
ServiceTracker tracker = new ServiceTracker(context, filter, null);
tracker.open();
T service = type.cast(tracker.getService());
tracker.close();
return service;
}
You can filter on any properties that the service is created with.
