This diagram shows the definition and mapping of roles. A relationship is shown in `ejb-jar.xml` between the `<security-role>` element, and the `<security-role-ref>` element and its `<role-link>` subelement. A relationship is also shown between these elements in `ejb-jar.xml` and the `<security-role-mapping>` element in `orion-ejb-jar.xml`. A relationship is also shown between `<security-role-mapping>` and the `<role>` element and `<user>` subelements in `jazn-data.xml`.
