Class ServiceStarter

java.lang.Object
  |
  +--com.wutka.util.ServiceStarter

All Implemented Interfaces:

java.lang.Runnable

public class ServiceStarter

extends java.lang.Object

implements java.lang.Runnable

Handles the starting of services by reading a file listing service names and the class names for the service implementation. It uses the Config class to find out the name of the file (looking for the config item "services.file"), or uses "servstart.dat" as the default file of services. The format of the service file is:

 serviceName serviceClass
 serviceName serviceClass
          .
          .

Lines that start with # or ; are treated as comment lines and ignored

After it loads a class, it starts the class, expecting it to support the Service interface.

Constructor Detail

ServiceStarter

public ServiceStarter(java.lang.String theServiceName,
                      Service theServiceToStart)

Creates a runnable instance that actually starts the service. By starting each service in a separate threads, the ServiceStarter is immune to locking issues caused by one service waiting for another to start before it can start.
