Class InvocationTargetException

  extended byjava.lang.Throwable
      extended byjava.lang.Exception
          extended byjava.lang.reflect.InvocationTargetException
All Implemented Interfaces:
Serializable

public class InvocationTargetException
extends Exception

InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor.

As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "target exception" that is provided at construction time and accessed via the getTargetException() method is now known as the cause, and may be accessed via the Throwable.getCause() method, as well as the aforementioned "legacy method."
