You can use access intent policies to help the product runtime environment manage various aspects of Enterprise JavaBeans (EJB) persistence.
You apply access intent policies to EJB Version 2.0 and 2.1 entity beans, and their methods, by using an assembly tool. A set of default access intent policies comes with the assembly tool. The Rational® Application Developer product provides supported assembly tools. You can also create your own custom policies. Entity beans are not supported in EJB 3.x modules.
