Return method CMP The return method for ejbCreate() CMP bean is null as CMP stands for Container-managed persistence which is an EJB container to manage the data by saving it to a designated resource, which is normally a database. The data must be defined in the container so that it can be managed within the deployment descriptors. The container in this case manages the data by saving it to the database and performing operations accordingly. CMP fields are usually mapped in the orion-ejb-jar.xml which is almost done in the same manner as "Primary Key". Have a complex primary key usually contains more than a single field.
