Accessing Ozone Objects
Hi!
Thanks for your mail. I do agree with you about writing
database and non-database objects in Java and access
them in Java. This is why I need ozone to store
Java objects so that I can use Java to access them.
Now, for example, I have a Person Java class that contains
attributes/methods that store name, age, etc. I can use
createObject method to create each Person object using
their name as the root object. I can use the same method
to store all people in my list like James, Tommy, Falko,
etc. Next step (where the question I asked), I need to
extract this people out so that I can show/load them
in a grid/treeview. So, how do I do it when ozone
didnt provide me a method to access these objects?
Regards
Kenny Go

One of the main goals of ozone is to close the gap between application
programming and database programming. For many typical Java apps it isn't a
good idea to have different langs, different type systems, different
abstraction levels for database and non-database objects. So the answer to
your
questions ist: both, database and non-database objects, are written in Java
and accessed with Java.
