> Subject: Generate ETag with Jersey
>
> Hello,
> I'm developing a RESTful service using GlassFish EJB3 and Jersey.
> My client application is WPF application written in C#.
>
> I would like to be able to have my client applcation "be updated" when something changes on the service side.
> Base on that I'm caching all the entities return from the service on the client side I can pretty easy find which entities are new and deleted by polling on the service resources every so often.
> The problem is how to know when they are updated.
> I though of using Etags which help me notice that an entities has change, maybe even reduce network usage.
>
> 1. Is that a good idea?
> 2. How can I generate ETags with Jersey in the mode no-code-needed way?
>
> Thank you,
> Ido.
