I guess you guys use hibernate's own connection pooling, but it is rather
simple and intended to help you to get started fast. It shouldn't be used in
production systems or for testing. Use a third party pool for best performance
and stability. For example c3p0, dbcp ...

Oracle support siquence. Use it for generating unique id. Why you want to use
String as id? Or you don't want to change generated files? It is better to
chenage id-type to something better, for example int/Integer. How to use
generators see in hibernate documentation, for example here:

Hm... I created java files with all field types String, and getters/setters for
them and SessionFactory is built. I only use other dialect, but I think it

Exception is:
org.xml.sax.SAXParseException: Attribute "generated" must be declared for
element type "property".
Seems like you are using wrong context for element. Give the mapping code with
parent of element.

Try this one:
em.createQuery("from ObjectA o where o in(select b.ObjectA from ObjectB b
where b in(:param))").setParameter("param", param).getResultList();

May be something like this:
"from ObjectA o where o.id in
(select distinct b.fk_objectA from ObjectB.fk_objectA b where b.id in :param)"

Try to play with Count() aggregate function.
For example
"from ObjectA o where COUNT(o.list) >=:param"

Use following code to create index with your's columns:
@Entity
| @Table(name="USERS")
| @org.hibernate.annotations.Table(
| appliesTo = "USERS", indexes =
| @org.hibernate.annotations.Index(
| name = "MY_INDEX",

I created the simplest jpa project. With only 1 entity.
package model;
import javax.persistence.*;

| @Entity
| public class Article implements java.io.Serializable {
|
| @Id
| @GeneratedValue(strategy = GenerationType.AUTO)
| private Short id
