No suitable driver - testing Application Module

Question

I'm using the AVEconnect JDBC Driver which I've registered successfully with the IDE as well as placed in my ClassPath.
I've created entity and view objects using the aforementioned driver and placed them in an application module. To verify the application module, I right click on it and choose "test"... the resulting debug information in the console window shows a "no suitable driver" error.
No changes have been made to the IDE generated code.
What else should I check?

Answer 1

I believe that neither MySQL nor PostgreSQL will work with BC4J as they currently stand. I did my testing with JDev9i, but I would imagine that the issues are the same (and even if you got something working, you'd never get it to work in JDev9i).
Basically, neither database has all the SQL features that JDev9i relies on - including subqueries (sub-selects) and Savepoints (for partial rollbacks). PostgreSQl has most of the features, but poorly implemented drivers at this time. Its updatable resultset implementation is woefully incomplete as it now stands, but I'm not sure how necessary that is for BC4J (I could't get that far in testing).
As somebody mentioned to me in an email afterwards, MySQL may have almost enough features sometime after v4.02 (4.0 is now in Alpha), with the exception of Savepoints (it might be possible to modify the driver to work around that issue - just ignoring the savepoint might work so long as you never have database commit problems). They talk about implementing subqueries, foreign keys, and some other things they'd need to work well with JDev and BC4J. But I bet this stuff is 6-12 months away.
