A workaround for the problem mentioned below is to use addSql:
crit.addSql(upper( INTERNAL_PRODUCT_ID) like '% + new Integer(
theProductModel.getInternalProductID() ).toString() + %' );
Note that in this case you have to use the actual db column name. Is this
the only solution?

In OJB document, I can find information on how to
handle collection mapping. However, I can not find

All,
Sorry again,
Rice,
I have not. It may be common, I was just wanting to see an example. It
may be a helpfull option one day.
From my experience i cannot visualize how an object would relate to
another object with a map. I am not saying your design is wrong. Maybe
I'll learn somthing new ;)

Hi Jose,
There seems to be some config problem with your repository:
From the stacktrace I learn that PlatformMySQLImpl produces a problem.
You should setup repository.xml to use the MsAccess platform and not the
MySql platform!

Sweet, that's perfect. The documentation was just missleading then when it

With the PB api you can ignore swizzling as you can use
optimistic locking

Can you expand on the PB approach a little? How is it that
