Is this possible? Situation is that I want to store some XML in my database, but keep it as generic as possible in case we need to deploy it to a difference backend. I realise I could store it as a String, but I believe MSSQL/Oracle optimise and validate XML if you store it this way, and let you search on it? ...
Hi, I look for a way how I can create a ddl for my jpa annotated entities. I prefer a pure java way for this. If possible it would be nice to have generate the drop statements too. ...

The situation : I am saving an entity e1 in the database and then i am adding e1 in another entity e2. when i try saving the e2 it is not able to find e1 and throws an index out of bound exception as i am loadi...
I have a PL/SQL function in an Oracle database that I can't change. This function takes a parameter which identifies an entity, creates a copy of that entity and then returns the ID of the copy. This looks something like FUNCTION copy_entity(id IN NUMBER) RETURN NUMBER I need to call this function from Hibernate. I tried creating a nam...

I'm relatively new to Hibernate and am trying to migrate a relatively simple existing database to something that I can use with Hibernate, and am looking for advice on how to structure my application. I have 3 types of entities: Item Category PropertyType Item and Category and PropertyType are all similar; they both have a name, des...
I have a hibernate mapping which looks like this: <hibernate-mapping> <class name="MutableEvent" table="events" mutable="true" dynamic-insert="true" dynamic-update="true"> <id name="id"> <generator class="assigned" /> </id> <property name="sourceTimestamp" /> <property name="entry...
This is more of a design than implementation question and it's going to be long so bear with me. It's best explained with an example: Let's say I have a business entity called Product with a bunch of properties (name, price, vendor, etc...). It's represented by an interface (Product) and implementation (ProductImpl, mapped in H...
We have a set of interfaces, used as an API, and referenced from other modules. A set of concrete implementations of those interfaces, private to the "main" app module. These classes carry a number of annotations (JPA as well as XStream for XML serialization). I've run into a problem. We have a user class which had a number of fields w...
I have two user Objects and while I try to save the object using sessio.save(userObj) I am getting the following error : Caused by: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.pojo.rtrequests.User#com.pojo.rtrequests.User@d079b40b] I am cre...
In a Java application stack with Spring & Hibernate (JPA) in the Data Access Layer, what are good methods of applying the password encryption (hopefully using annotations), and where can you find out more about getting it done (tutorial, etc)? It's understood that I would use a JCA supported algorithm for encrypting the passwords, but I...
I have a database table using an enum. This is already working with hibernate (using XML), and I'm trying to convert it to annotations as this is one of the last pieces to still be using xml notation. The column definition: enum('Active','Pending','Cancelled','Suspend') The following works: <property name="status" column="S...
OK, this is a follow-up question to this one, since I am really confused now. Suppose I have a one-to-many or many-to-many association between entities Person and Event such that a Person class in Java contains a Set<Event>. (Let's ignore whether Event contains a single Person or a Set<Person>.) Events are entities stored in a database...

I want to get all clients, houses, and problems. Can Rent...
Lets assume a simple Spring MVC Controller that receives the ID of a domain object. The Controller should call a service that should do something with that domain object. Where do you "convert" the ID of the domain object into the domain object by loading it from the database? This should not be done by the Controller. So the service m...
Consider the following code: @Entity @Table(name = "a") public class A implements Serializable { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name="id") public int id; @Transient public B b; public B getB() { return B; } } When I fetch A, I'm manually filling B (another hib...
I'm trying to get started with Hibernate, and when executing my program I get an error during initialization.
