I *GUESS* it is not required if your application is deployed on a single server not configured with clustering.
It is required for clustered environment aswell as for distributed environment, it is because the DTO has to be shipped.

No It's not mandatory to implement Serializable . If you are working in clustered environment / distributed architecture and your DTO is tranfered into another environment the it's mandatory to implement.
