Ok, my class works, after change JDBC-TYPE from FLOAT to REAL.
I will take care of these type mapping.
Thank you.

In OJB.properties you have to configure to use

I'm using 1.0 rc1 with the PB API. I'm noticing that I don't have any isolation
between multiple brokers when caching is enabled. For example:

PersistenceBroker broker1 = PersistenceBrokerFactory

Hi,
I am testing OJB's tutorial 5 using OJB ver 1.0-RC1 to persist to MySQL
ver. 3.23.54 with MySQL JDBC driver ver. 3.0.6. All is fine until I set
autobuild property to true. Once I have set this, I am thrown a connection
closed exception. The detail of the exception is as shown below
[JDO] DEBUG
Probably a dumb question but. is there something like query.bind() that I can with
PB? I want to use PB because it seems more flexible but I *really* like being able to
create a query and use bind() like I can with ODMG.
Thanks

Hi Dogie,
we adopt a new concept to make the PBKey
independent from the repository.xml, by using
the 'jcd-alias' name in PBKey.
Thus in your case you should do somthing like

or
PBF.createPersistenceBroker(new PBKey("default", "sa", "passwd"));
