FAQ
This is possible theoretically, but I haven't thought deeply about
Hessian replacement scenario. I am personally planning to use it as a
framework for backup/restore solution for huge databases that allows
to apply custom rules to data filtering and processing of the data.

If anything, this may end up being a replacement of
org.apache.cayenne.xml package. XStream provides a well-defined
(de)serialization lifecycle that allows to build various interceptors
and custom serializers. Also it has "plugins" for serialization
formats. So for example out of the box it can produce either XML or
JSON.

Comparing that to Hessian, my wild guess is that XStream won't be
faster (even with compact JSON output), but it certainly more
developer-friendly (cleaner API, better documentation, etc).

Hi Andrus,

Is this feature a replacement for Hessian serialization? What are the
benefits of using XStream (is it faster, etc)?

Thanks
