I'm using db4o as persistence engine for my ZK-based Jease-project, maybe you can have a look at it to get some ideas.

The "recommended" approach for using db4o with ZK is:

- Open your db4o-database in a ServletListener and hold a reference to the opened database in a static variable.
- If you need to operate against db4o, just use the reference stored in the static variable in your other classes.

Cheers, Maik

I made it in consultation db4oDB.java file that has a reference to objetcontainer db.

extracted data then stored in a List of objects and display them on the grid.
