That is useful (for instance) if you are using Session clustering of ... |

In my application, I am implementing Serializable interface for all java beans. I know that, I am doing it for the persistence. But I neither use ObjectInput/OutputStreams to read and write to file system, hard disk and nor handle any other kind of persistence when system crashes/or when ... |
4. Good way to cast unknown Serialized Object types? coderanch.comI have a web application (written primarily using Struts) that allows long database queries (and other processes that could take a while to complete) to run as background Threads.

15. Where Serialization is implemented coderanch.comHi, Java serialization is implemented internally by the JRE itself. You don't need to do anything special, other than marking your application class as implementing Serializable interface.

It's extremely rare for web apps to store data in java serialization ... |
