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. |

Is WSDL the indispensable API? Many developers consider Web Services Description Language (WSDL) the new software design view. WSDL offers a verbose, ASCII, standard, and language-agnostic view of services offered to clients. WSDL also provides noninvasive future-proofing for existing applications and services and allows interoperability across the various programming paradigms, including CORBA, J2EE, and .Net. This article shows a service's WSDL view, then explains how you can generate client and service implementations for Java and C#. It finishes by discussing possible sources for initial WSDL view generation. |
