How to create java desktop application with offline and online database, syncing periodically?

Question

I want to create java desktop application, which stores it's data offline in a database (not just some config files). The application should work fine when the user is offline. When the user becomes online, the offline database should be able to sync with the online master.

Any ideas which technologies can be used to achieve this?

This has been discussed on stackoverflow a lot and it usually boils down to: don't roll out your own solution - This is a very specialized field - Look up SymmetricDS. It does what you want.
