Can we get owner tree of an object to see whether object ...

Same question as this, only I'd like to do it in Hibernate (using grails if that matters). So the domain class looks like this class LinkedElement { LinkedElement precedingElement String someData } and I'd like to query all elements in their linked order (where the first LinkedElement has null as the precedingElement). Is this po...

What is the best type for storing IP-addresses in a database using Hibernate? I though Byte[] or String, but is there a better way, or what do you use? @Column(name = "range_from", nullable = false) public Byte[] getRangeFrom() { return rangeFrom; } public void setRangeFrom(Byte[] rangeFrom) { this.rangeFrom = rangeFrom; } ...

Hi. I'm trying to generate a database schema for my project using hbm2ddl. I'm using JPA 2 annotations to specify how the schema should look like. Right now I'm having some issues with inherited id's. I have an abstract super class, let's call it AbstractSuperClass, which looks like this: @Entity @Inheritance(strategy=InheritanceType....
Background: Hibernate connects to a database using a username and password entered into a GUI. Upon failure, instead of propagating the error up as an exception, it comes out as a stack trace in the logger. I don't know where the exception is being caught at. Also a tiny bit troubling is the following block: if (reason != null) { ...

In the sample DDD project written by Eric Evans (http://domaindrivendesign.org/examples) there is a Cargo class which is an entity object and is mapped to db table using hibernate. That Cargo domain object consists of several value objects one of which is Delivery. This Delivery value object is quite complex as it has some 10 fields. Non...
Hi, I was reading the below blog about hibernate optimistic locking. I am planning to use it with hibernate. But, I have one concern. we have java code and c++ code, both connect to one database. While, java code can use hibernate to achieve optimistic locking, I want to make the c++ code do the same thing. Also, c++ code is using some ...

I'm trying to create a domain object that contains objects in a read-only fashion but be able to modify which objects it points to. So in the example below I would like Hibernate to handle populating the Account and Category objects but I don't want to ever update those objects. However I may wish to change which Account or which Categ...
