1. A method for gaining a reference to a first service by a second service in a computer system comprising:

  • enabling definition of a service connector interface in conjunction with said first service;

    subsequently invoking said service connector interface in conjunction with said second service, wherein said subsequently invoking includes instantiating said service connector interface at said second service; and

    gaining reference to said first service by said second service comprising the steps of;

    retrieving a service instance at said service connector interface;

    obtaining a service reference from said first service; and

    returning said service reference obtained from said first service to said second service;

    wherein said steps of subsequently invoking said service connector interface and gaining reference to said first service are carried out by an application program operative in conjunction with said second service and wherein the service connector has no prior information regarding the first service prior to the gaining reference step, the instantiating including reading a configuration file providing an indicator for said service connector interface;

    identifying a particular instance of said first service that said second service desires to invoke and wherein a latest instance of said first service is invoked if a particular instance of said first service is not specified.
