Oracle 9iR2
Java 1.4
Windows XP
JBuilder 7 SE


I am going to write a Java program which will perform a SQL query
to an Oracle server and display the result, and would like to
review all my alternatives.

The program will be relatively simple:

  - it will run on Windows XP
  - it will NOT make use of a browser
  - there will be a single SQL query
  - the result is just one row

This is going to be my first non-trivial Java application.
I recently purchased Borland's JBuilder 7 SE.  I also downloaded
Oracle's JDeveloper, but haven't tried it out yet.

Some of my concerns/questions are:

  - Are the Enterprise Editions required or just more convenient?
    I am refering to both Borland's JBuilder EE and Sun's J2EE

  - Can I just download Oracle's JDBC driver and somehow (how?)
    make it available to JBuilder SE?

  - Do I need to install the Oracle 9i Client on the Windows PC?

A tutorial program from the Nutshell J2EE book is included
below, that's pretty much what I neeed (plus the GUI stuff,
of course).

  - Where can I find the documentation for the method
    DriverManager.getConnection?  

TIA for your assistance.

Regards,
