Unable to retrieve endpoint for a given service QName
-----------------------------------------------------
Key: SMX4-204
URL: https://issues.apache.org/activemq/browse/SMX4-204
Project: ServiceMix 4
Issue Type: Bug
Affects Versions: 4.0-m2
Reporter: Lars Heinemann
I got the following helper function which used to work in older SMX 3 and 4
versions (latest known of SMX4 is 28th of january?).
Today in the morning I built the latest trunk and the function doesn't work any
longer.
/**
* checks whether the given service is available in the nmr or not
*
* @param context the component context
* @param service the service to check for
* @return true if at least one endpoint is available for the
* given service, otherwise false
*/
public static final boolean isServiceAvailable(ComponentContext context,
QName service) {
ServiceEndpoint[] eps = context.getEndpointsForService(service);
return (eps != null && eps.length > 0);
}
I tried to extend this function that in case there is no such service
registered, I call the method context.getEndpoints(null) to retrieve all
registered
endpoints (like API Doc says) but it ends up in a NPE which is not JBI
compliant.

Any thoughts on that? It must have been broken withing the last few days.
