CFCatch Java Exceptions
Did you know that you can catch java exceptions by class name with
cfcatch? It's not documented on the
cfcatch tag documentation (as of CF8), but it works... Here's an example:
<cftry> <cfset list = CreateObject("java", "java.util.LinkedList")> <cfset list.get(5)> <cfcatch type="java.lang.IndexOutOfBoundsException"> Index outta bounds </cfcatch> </cftry>
There is one special exception that Mark Mandel has blogged about, and that is if the exception is caused by a class that was loaded by a different classloader, cfcatch won't be able to catch it by type. Perhaps that's why this feature is undocumented?
