Is there any plugin available for Eclipse or Netbeans or any other IDE which can help me generate the hbm.xml by directly reading the schema from the database. Writing those XMLs seem to be unnecessary waste of time, and feel it should be automated. ...

Looking for something between simply downloading struts and bolting on vs full-fledged portal software such as Liferay or BEA Portal. Would be great if the database connectivity supported EAV models but allowed developers to think in traditional relational 3NF terms. ...
Hello, I have a code using JPA with Hibernate 3.3.x. This Java code can be used with schemas stored either on Oracle 10g or MySQL 5.1.x. Tables are defined with constraints to define unique records. When a constraint violation occurs, I want to retrieve the constraint name from the exception. With Oracle, the constraint name is properl...
I'm having problems with a NonUniqueObjectException thrown by Hibernate. Reading the docs, and this blog post, I replaced the call from update() to merge(), and it solved the problem. I believe I understand the reason for the exception, and why changing the method fixed the problem, in terms of disconnected objects and session boundar...
When working with programmatic transactions in Hibernate, is it necessary to explicitly call rollback if an exception occurs, or will the framework take care of calling rollback if there is an unhandled exception? The code below seems like the safe approach (albeit ugly code) to ensure rollback, but i'm wondering if there is a more elega...

I have debugged this and hib...
I am developing an application which will be integrated with thousands of sensors sending information at every 15 minute interval. Let's assume that the format of the data for all sensors is same.

Example: in my data model I have a many-to-many relationship between Role and Order, via a Permission table that have an extra column for the name of the permission. E.g., the 'admin' role can view and modify orderA, but only view orderB. The permissions' names are, of course, 'view' and 'modify'. In classic db design fashion, the forei...
