Steps for Converting an EJB 1.1 to an EJB 2.0

To convert an EJB 1.1 bean to an EJB 2.0 bean, you can use the WebLogic Server
DDConverter utility.
BEA Systems recommends that you develop EJB 2.0 beans in conjunction with
WebLogic Server 7.0. For 1.1 beans already used in production, it is not necessary to
convert them to 2.0 beans. EJB 1.1 beans are deployable with WebLogic Server 7.0. If
you do wish to convert 1.1 beans to 2.0 beans, see the
Programming WebLogic Enterprise JavaBeans for information on how to do this
conversion.
The basic steps required to convert a simple CMP 1.1 bean to a 2.0 bean are as follows:
1. Make the bean class abstract. EJB 1.1 beans declare CMP fields in the bean. CMP
2.0 beans use abstract
Beans will use
String getName()
this modification, the bean class should now read the container-managed fields
with the
