org.eclipse.persistence.platform.server.ServerPlatform
PUBLIC: This is the interface describing the behavior for ServerPlatformBase, and any other class that wants to provide behavior for a server. This interface provides the behavior for - Which external transaction controller to use - Whether or not to enable JTA (external transaction control) - How to register/unregister for runtime services (JMX/MBean) - Whether or not to enable runtime services - How to launch container Threads Any subclasses of ServerPlatformBase created by the user must implement this interface. public API: String getServerNameAndVersion() @see ServerPlatformBase
