InvocationTargetException (Java Platform SE 6) (original) (raw)
java.lang.reflect
Class InvocationTargetException
java.lang.Object
java.lang.Throwable
java.lang.Exception
java.lang.reflect.InvocationTargetException
All Implemented Interfaces:
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 thegetTargetException() method is now known as the cause, and may be accessed via the Throwable.getCause() method, as well as the aforementioned "legacy method."

getCause
public Throwable getCause()
Returns the cause of this exception (the thrown target exception, which may be null).
Overrides:

Returns:
the cause of this exception.
Since:
1.4
