Customized EJB security in JBoss The current Enterprise JavaBeans specification supports basic declarative, role-based access-control mechanisms, but provides limited support for coding application-specific security checks. Moreover, it doesn't define any way to factor out access-control code from business logic, or to integrate external authorization services. The open source, J2EE-compliant JBoss application server features a protection-proxy security architecture that will help you overcome these restrictions. |
