A status report on my problems.
I went back to square one and managed to get things to work. However, in
the process I found some glitches. Maybe they are finger trouble on my
part, maybe they are omissions in the code or the documentation.
1. The variable ${jcdAlias} is used in repository_database.xml, but
nothing sets it. I also cannot find where it is picked up from.
2. Repository.xml is not included in obj-blank.jar
3. The various DB profiles are not included in ojb-blank.jar
4. JdbcRuntimeDriver has to be added to build.properties before doing
the ant build step.
I now have PB working, but I cannot get ODMG to work. I am using rc5 and
keep getting NPEs from query.create(), sometimes with associated syntax
'errors'. My table already exists and contains about 6M rows. The code,
which is intended merely to verify basic connectivity, is below
select betid from Entity => NPE with no other diagnostic
select count(*) from Entity => NPE with 'unxexpected token "(" found,
expected "from"'
select betid as b from entity => NPE with 'unexpected token "as" ...'
select betid b from Entity => NPE with 'unexpected token "b" ...'

Hi Raphael,
from your stack trace I can see you manipulate many of the default jdbc
settings:

OJB try to perform a validation query "a query", this will fail (not SQL
compatible ;-)). Maybe this is the problem you have.

again, I recommend to use default settings first and only change
settings step by step.

I recommend to set batch-mode false to avoid side-effects. You can try
to enable it when all stuff is working fine.
> useAutoCommit=AUTO_COMMIT_IGNORE_STATE
Again default is '1', you set '0'. But in managed enviroments you need
to set '0'. Do you try to run OJB in a managed environment? This
wouldn't be a good starting point for a newbie ;-)
ahh, now I see in your repository_database.xml what you have done. You
picked up a jdbc-connection-descriptor used for junit testing and set
you DB properties. This will not work, because the used properties don't
be valid.
Did you see
http://db.apache.org/ojb/getting-started.html
http://db.apache.org/ojb/platforms.html
As Brian said before, recommended to use this way first to setup your
environment. In build.properties you can set your DB. In the profiles
directory you can find "templates" for all supported databases. Pick the
oracle file and set your properties.
regards,
Armin
