I assume you are referring to Commons NET here. You should probably use isAvailable() instead as that performs more checks.
However as the method Javadoc says, the only sure way to check if the connection is still available is to use it. Commons NET does not provide idle connection checking and so there is no event for it. You will need to implement your own checks, e.g. using sendNoOp() every so often. Care must be taken to ensure that you only send such probes when the connnection is not being used otherwise you might interfere with other commands. Note that Commons NET is only intended to provide basic access to Internet protocols. For example it is not intended to replace a full FTP Client, merely to provide some building blocks.
