Handling runtime exceptions with ColdFusion tags
Description
In the second try block, catches any errors other
exceptions and rethrows them up to the
outermost try block.
Ends the second try block.

exceptions by displaying an error message that
includes the exception type and the exception's
error message. Because there was no code to
try that is not also in a nested try block, this
tag handles only errors that are rethrown
cfcatch
from the nested blocks.
Exits the custom tag and returns to the calling
page.
Ends the catch block, try block, and initial
block.
