handle

public void handle(String target,
 Request baseRequest,

Description copied from class: ContainerLifeCycle

Starts the managed lifecycle beans in the order they were added.

Overrides:

doStart in class AbstractHandler

Throws:

AbstractLifeCycle.StopException - If thrown, the lifecycle will immediately be stopped.

Exception - If there was a problem starting. Will cause a transition to FAILED state

doStop
