Java - Throwable to Exception

I am currently using the play2 framework.

I have several classes which are throwing exceptions but play2s global onError handler uses throwable instead of an exception.

for example one of my classes is throwing a NoSessionException. Can I check a throwable object if it is a NoSessionException ?

Solution

  • You can use instanceof to check it is of NoSessionException or not.

    Example:

    if (exp instanceof NoSessionException) {
...
}

    Assuming exp is the Throwable reference.
