com.sun.messaging.jmq.jmsserver.service.ServiceManager
This class is the manager which creates Services by calling the service handler associated with the service type.
A service is defined with a minimum set of properties:

jmq.service..type = jmq.service.serviceclass..class = jmq.service.serviceclass..props = < , seperated list of properties to watch>

e.g. a "standard service" uses both a protocol (with its properties and a service
A service called "broker" properties might look like:

# list of known services jmq.service.list = broker,admin,ssl,http,httpadmin # list of active services jmq.service.activelist = broker,admin # definitions for the standard service jmq.service.broker.type=dedicated jmq.service.serviceclass.standard.class= com.sun.messaging.jmq.jmsserver.service.imq.IMQService

This code does a lot of string manipulation when the service is created which will make it fairly slow. Since this code is rarely called after startup, the performance should be acceptable.
