public exception 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 {@link #getTargetException()} method is now known as the cause, and may be accessed via the {@link Throwable#getCause()} method, as well as the aforementioned "legacy method."

InvocationTargetException

protected InvocationTargetException()

Constructs an InvocationTargetException with null as the target exception.

InvocationTargetException

public InvocationTargetException(Throwable target)

Constructs a InvocationTargetException with a target exception.

Parameters:

target - the target exception

InvocationTargetException

public InvocationTargetException(Throwable target,
                                 String s)

Constructs a InvocationTargetException with a target exception and a detail message.

Parameters:

target - the target exception

s - the detail message

getCause

public Throwable getCause()

Returns the cause of this exception (the thrown target exception, which may be null).

Overrides:

getCause in class Throwable

Returns:

the cause of this exception.

getTargetException

public Throwable getTargetException()

Get the thrown target exception.

This method predates the general-purpose exception chaining facility. The {@link Throwable#getCause()} method is now the preferred means of obtaining this information.

Returns:

the thrown target exception (cause of this exception).
