Re: Plz Help....cryptography

Hi,

There is no built in query language except java. You query your object model 
using standard java techniques (traversing collections, using comparable, 
equals etc.) See the FAQ for more options.

I've used JXpath in some application i have developed. An example of this is 
in the PetStore port that you can download from the files section in 
sourceforge. There are other solutions that other users have taken. We are in 
the process of standardizing one or two approaches to querying large object 
graphs that will come built into Ozone in the future but that work has just 
begun.

Regards,
Per
