getServiceReferences(...) returns service references guaranteed to be classloader compatible with your bundle ie. you should not get a ClassCastException when you cast the service instance to the appropriate class/interface. ( basically filters the set with isAssignableTo... ) getAllServiceReferences(...) returns all service references matching the request, regardless of whether they are classloader compatible, so you may get ClassCastExceptions if you tried to actually use the service instance see the method javadoc (http://www2.osgi.org/javadoc/r4) for the algorithms used to create each set of references Kind regards, > -- > -------------------------------------------------- > David Lindelöf > Product Developer > Adhoco AG > Technopark > Jagerstrasse 2 > 8406 Winterthur > tel +41-52-264.5070 > mob +41-79-415.6641 > fax +41-52-264.5099 > e-mail [EMAIL PROTECTED] > url http://www.adhoco.com > weblog http://www.visnet.ch/smartbuildings/ > -------------------------------------------------- > > That money talks, > I'll not deny, > I heard it once, > It said "Good-bye. > -- Richard Armour > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > -- Cheers, Stuart
