Hi,

We are hoping to use FreeTDS as the database driver for the J2EE reference
EJB application server.

The J2EE server starts up fine and registers the driver with the JNDI
service.

We have a couple of questions :

1. In order to generate SQL for Container managed Entity beans, the
Deployment code in J2EE tries to get hold of the SQL type info from the
jdbc driver. The method getTypeInfo() on DatabaseMetadata is not
implemented. Are there any plans afoot to do this ? If not i will probably
have a go at it myself - is there any more information that might be
useful ?

2. The reason we want to use a SQL db server rather than the standard
cloudscape server (bundled with J2EE) is that cloudscape seems to have
issues with Transaction Isolation. We were hoping we could resolve these
using a SQL jdbc driver. What level of transaction support is currently in
the FreeTDS code ? again, we may consider working on this if its needed.
