Im finding a way to generate key for table and it needed to be increment one by one. like we did earlier in hibernate mapping file: like

Code:

<class name="com.Employee" table="Employee">
     <id name="empid" type="long" column="id" >
        <generator class="increment"/>
     </id>

    <property name="empname">
         <column name="name" />
     </property>
</class> 

I want do this in my application and then insert incremented value to the table.

I tried this option:
@GeneratedValue(strategy=GenerationType.IDENTITY)
@GeneratedValue(strategy=GenerationType.AUTO)

but it doesn't work.

Please help....

regards,
Dil.

The increment type generator is not available in JPA annotations.

You need to use Hibernate specific annotations if you want to use the 'increment' generator. See http://www.hibernate.org/hib_docs/annot ... identifier for some information about it.

I found the solution:

Code:

     
    @Id
    @GenericGenerator(name="generator", strategy="increment")
    @GeneratedValue(generator="generator")
    @Column(name="ID")

    public int getId() {
        return id;
    }

This really works........
