All the exceptions that occur in commands are wrapped into ECException and thrown back. This is of two types :
1. ECApplication Exception : Exception due to any application parameters.
2. ECSystem Exception : Exception due to any system issues.
isRetriable() method of a Command
The isRetriable method returns a Boolean value which specifies whether the command can be retried on a transaction rollback exception. The isRetriable method of the new controller command's superclass returns a value of false. You should override this method and return a value of true, if your command can be retried on a transaction rollback exception.
