Hi,
I've searched the forums and documentation and the Bauer book, and have just downloaded the source and am beginning to pour through that for answers.
But in case someone else knows what's going on (or can at least point me in the right direction)...
I am writing a utility that will allow its end-users to change the database schema (and subsequently the beans too). Basically, this is to allow for user-defined fields. We can't allow the end-user to use the SQL Server Enterprise Manager or anything else because we need to keep db independence.
I'm testing it out, and everything goes ok until I try to run hbm2ddl via an ant task. I don't understand why it's complaining that "No identifier specified for entity: com.hti.ez.sah.generated.TestBean" when I can use code that is generated by the reverse engineering with annotations turned on just fine.
Here's the code I'm trying to compile:
Code:
package com.hti.ez.sah.generated;
