I wrote a code generator for Entity Beans. THis is fairly easy because the
DB meta data can tell you about the tables and there relationships. This
code is core to much of the system that I work on and now I can add code gen
for other repetitive tasks that access the entity layer. When writing code
gens you need to understand the task (it's repetitive nature) very well.
After you write parts by hand a couple of times, you will identify how the
task should be done with a code generator.

>We wish to create a Code Generator, which will dynamically generate the

>Doubts:

>The following doubts exist:
>1. Is it advisable to use EJB's or will a simple bean model using MVC
>suffice.
>2. In case we use EJB, which is better CMP or BMP. Remember that we
>span multiple tables.
>3. In case we use BMP, then is it practical to write a code generator
>for BMP's - I mean is it repetitive code, and is it possible to write it by
