The Command.execute()
, Command.invokeRPC()
, and CommandHandler.executeCommand()
methods must throw exceptions of class atg.integration.CommandInvocationException
. This exception is intended to wrap any underlying exceptions that might be thrown by a particular transport or remote system. This exception must wrap the underlying exception, rather than copying its message, so that stack trace printouts include the information from the underlying exception.
The CommandInvocationException
class has two useful subclasses:
atg.integration.CommandTimeoutException
can be thrown when an RPC call times out. This is a special case, since a timeout doesn’t indicate whether the RPC call succeeded or not.atg.integration.InvalidInputException
can be thrown if the input object passed to theCommand
is invalid.
