I'd be interested in hearing responses to this as well, I'm using a
bookstore in my test, but the error is the same (RH7.2, Torque3-dev,
MySQL). I am having the same problem as well. When I call c.save(), I
get the following stack trace:
java.lang.NullPointerException
at org.apache.torque.util.BasePeer.doInsert(BasePeer.java:762)
at com.kazmier.om.BaseAuthorPeer.doInsert(BaseAuthorPeer.java:169)
at com.kazmier.om.BaseAuthorPeer.doInsert(BaseAuthorPeer.java:435)
at com.kazmier.om.BaseAuthor.save(BaseAuthor.java:337)

at com.kazmier.om.BaseAuthor.save(BaseAuthor.java:285)
at com.kazmier.MyTest.main(MyTest.java:19)
However, if I replace c.save(), with AutherPeer.doInsert(c), everything
works ok. So I would speculate that if you replace your c.save() with
CivilizationPeer.doInsert(c), that it would work. Torque is completely
new to me, but I was able to build the source, get it to create my
database, but I get stuck with my simple test app. Any suggestions?
I've searched the archives for help, but I haven't found anything yet.
In addition, I am also a little confused with the concept of the
"default" database in the Torque properties file. I explicitly set the
database name in my schema file, then added appropriate lines to my
torque properties file, but the id-table-schema.xml doesn't explicitly
define a database name in the <database> tag, so in my sql/create-db.sql
file, I had a lines like this:
drop database if exists default;
create database default;
drop database if exists bookstore;
create database bookstore;
I'm using MySQL and it seems that MySQL gags on the keyword "default".
So I just added a name to the id-table-schema <database> tag to be
"bookstore" and everything was ok. Is this what I should do? Or is the
behavior I saw the result of an error on my part?

I got stuck Sunday evening, so as a peace offering :), before I posted
my questions to the mailing list, I decided to start the creation of a
standalone Torque tutorial that hopefully might someday be included on
the Torque pages for new users like me. I was going to complete as much
as possible before posting to prove that I am not just a leech, but when
I saw this post, I figured I'd chime in here. To prove that I'm not
blowing smoke, here is the start of the tutorial and the general outline
of it. Once I get my first Torque app running, I should be able to
complete it.

Any comments would be welcome, there isn't much there yet, but I tried
to outline what I thought would be in the tutorial, if I am missing
something, then let me know.
Thanks!
Pete
