Hi folks
i know that this issue has been reviewed a lot of time but i m too confusing what is the right way to implement the auto-increment key using JBOSS 3.2.4 with Xdoclet supported by MyEclipse.
I saw on the www a lot of chunk code example that say everything works on this way …bal bla bla but i was not capable to implement that.

I need someone to confirm me if what i learned about auto-increment is right or not:

a) in the ejb-jar i must insert
* @–jboss.unknown-pk class=”java.lang.Object”
* auto-increment=”true”
* column-name = “IDUtenti”
* jdbc-type=”INTEGER”
* sql-type=”int”
* @–jboss.entity-command name=”mysql-get-generated-keys”

b) i must not implement the getIDutenti …and setIDUtenti cmp method
c) i must not declare in class definition
@ejb.bean name = “Utenti” the primary-field=”IDUtenti” << NOT!!
d) the IDUtenti column in the database must be created with auto-increment option
e) cross your finger and pray

..anyway i did that but the only result i get is “The primary key field is null”. do u have some full example i can try to check if this things works?

thanx

I will ask our XDoclet guru to look at this.

Try putting the following xdoclet tag on your primary key field.

*
* @jboss.persistence
*       auto-increment="true"
*
