Subject RE: I hate IdGenerator
Date Mon, 23 Dec 2002 07:43:22 GMT

I found a solution to the problem and sent it already but mail server
failed. Here it is:


It was my stupidity. There was another *big* difference between 
applications, (web and and non-web) Torque.properties. I innocently
commented the torque.database.project.adapter configuration line.

Since Tomcat provides the pooling and Torque uses that pool from the
JNDI I thought Torque does not need to know which adapter to use.

I think Torque documentation should mention if adapter is not specified
Torque cannot manage native auto incremented primary keys.

And I think Torque documentation should be much bigger and more 
comprehensive that it is today. I plan to contribute (if approved 
of course) after this project completed.
