this file was written manually. it is used by the instantDB ScriptTool =
to
perform database operations like creating tables and insertinmg test =
data.

What "other objects" do you have in mind?

The documentation for the instantDB ScriptTool is here:

/idb
4_0/sample-applications.html#scriptool

As far as I see, there is no option to specify  a user or password :-(
So you will have to write the DDL manually... Will not be too difficult =
for
just the two tables...=20

You are welcome to contribute. OJB currently has no tools for forward- =
or
reverse engineering or graphically composing the O/R mappings. So your
know-how in this area will help a lot!
