Exploring J2EE Security for Applications using LDAP
This article is loosely based on prototyping a number of J2EE applications constructs, such as servlets, EJB, MDB (Message-driven Beans) and JSP implemented using LDAP (Lightweight Directory Access Protocol) for application authorization. The applications were built in order to understand standard J2EE security and IBM WebSphere extensions. The article identifies key interfaces within WebSphere Application Server Version 5.x (WAS) or any J2EE compliant application server that need to be configured in order to build secure applications.

Object Slicing and Component Design with Java
Object-oriented systems are usually partitioned into layers of related responsibilities and only dependencies in one direction are allowed, from higher layers (more specific, less reusable) to lower ones (more general, more reusable). Classes in higher layers can extend or wrap classes in lower ones, but not the other way around. Learn more about object slicing. Continue Reading

Part 6 - Securing Web Services with Single Sign-On
Web Services are arguably the most heterogenous distributed technology ever. A typical Web services setup will make use of many different technologies, object models and programming languages, which might include simple Perl scripts and standalone Web services implemented in C++ or Java, through to sophisticated applications build on top of J2EE application servers. Being able to interact across such diverse environments is one of the strengths of Web services, but it has a price: it becomes difficult to secure such systems. It is hard to find a common security standard for all involved technologies. Today we will talk about single sign-on, the security architecture that brings a flexible an interoperable way of securing heterogenous systems. Continue Reading
