How to create an Index on your Entity Beans?
Written by Mark S.   
JBoss recipe of the day

You can use the @Index annotation with EJB3 in Hibernate 3.2.X to create indexes automatically when an entity is deployed.
This annotation can be put either on the Table annotation or directly on the entity property.

Examples:

@javax.persistence.Table(name = "items")
@org.hibernate.annotations.Table(appliesTo = "items", indexes = { @Index(name = "INDX", columnNames = { "idItem" }) })


@Index(name = "IDX", columnNames = { "idItem" })
public String getIdItem() {
return timestamp;
}
