RE: beginner question: Ozone & java.util collections

Hi, I never got the time to write a full description of how this little app
works but you can take a look and see for yourself. I am not even sure I
implemented everything the right way, but it works and it uses the java

In the attached file there is a gif file with the object model I used.

The way it works is:

You add manufacturers and buyers to an object called uploadProject.

Once you do this you can also add buyers to manufacturers.

Buyers also have files that are related to them but there is a web interface
that handles this using JSP and servlets which I did not include here.

So play around with it and let me know if you have any questions.


It is all compiled so you should be able to run it. Follow the install.html

Subject: beginner question: Ozone & java.util collections

Is there an Ozone example available that uses java collections (e.g. 
java.util.TreeSet) rather than the DXLib collections?

As I understand the documentation all database classes in Ozone must 
implement OzoneCompatible and the remote interface and be postprocessed. I 
understand how to write the remote interface but not how to do the 
collection implementation.

Any guidance would be greatly appreciated.



BTW, I'm curious why the DXLib classes were used for Ozone instead of the 
standard Java collections. What's 'nifty' about them that isn't 'nifty' 
about the Java collections?
