org.jppf.startup
Interface JPPFDriverStartupSPI

All Superinterfaces:

JPPFStartup, Runnable

public interface JPPFDriverStartupSPI
extends JPPFStartup

This interface class represents objects that are run at server startup time.

More precisely, they are run just after the server MBeans have been registered.

Classes implementing this interface must have a public no-arg constructor and implement the run() method.

Server startup classes allow a developer to perform initializations at runtime, such as load specific APIs, create connection pools, subscribe to the monitoring MBeans notifications, etc. The range of applications is quite broad.

They are looked up by using the Service Provider Interface (SPI) lookup mechanism. For the SPI to find them, proceed as follows:

• in the classpath root create, if it does not exist, a folder named META-INF/services
• in this folder create a file named "org.jppf.startup.JPPFDriverStartupSPI"
• the content of this file is one or more line(s) with the fully qualified class name of an implementation of this interface
• to specifiy multiple implementations, just put one per line in the file
• there can also be multiple META-INF/services/org.jppf.startup.JPPFDriverStartupSPI resources in the classpath (for instance in multiple jar files); all of them will be looked up and processed
