Generating OID's for PK

[prashantpatel]

Is there a service or api in jboss to generate unique id's for a new record (ie pkey), i have read in the pervious post that a class named
"org.jboss.varia.autonumber. AutoNumberFactory" which provides this facility is there any api doc to refer to this, does some one have a example on this oid generation for ejb model. Which is the good design to generate unique id's (espically for ejb model)?

download EJB design patterns ( http://www.theserverside.com/books/EJBDesignPatterns/index.jsp )

And read the UUID for EJB pattern.. IT describes a way to generate unique UUID's over time and (cyber)space; real neat :)

Besides that it also features two other patterns; one to get an incrementing counter and one that uses stored procedures (BMP)
