Today’s production applications need to be able to allow specific users to perform specific tasks ... and, equally important, need to be able to disallow specific users from performing specific tasks. JBoss uses the Java Authentication and Authorization Service (JAAS), along with the concepts of “users” and “roles,” to meet these requirements. Join Mike Simpson as he tackles these issues on “JBoss and Security.”

JBoss comes with its own lightweight database, which can be handy for testing and for managing transactions that don’t need to survive a JBoss restart. However, you may want to integrate JBoss with your own production database. Join Mike Simpson as he reveals JBoss’ JDBC-integration capabilities on “JBoss and Databases.”

JBoss offers two mechanisms for “persisting” (saving) information to disk: Bean-Managed Persistence (BMP) and Container-Managed Persistence (CMP). Which should you use? What are the advantages and disadvantages of each? How do you configure each in JBoss? Join Mike Simpson as he discusses “JBoss and Persistence.”

JBoss is a Java-based “application server” -- integrating and securing individual modules. But what does that mean for you as a developer? And do you have to use Java for your modules? Join Mike Simpson as he discusses “How JBoss Stacks Up against Other Application Servers.”

Java's collection classes provide ordered logical means of dealing with user-defined groupings of objects. Generics – a new feature of Java 5 that has been improved in Java 6 – allows a programmer to specify that a particular collection should only support a particular type of object. Join Mike Simpson as he leads you on a tour of “Collections and Generics in Java.”

There is a pithy aphorism in software design that says “There’s never time to do it right, but there’s always time to do it over.” The best way to assure software quality is to design and test your software to “build in” quality instead of trying to “bolt it on” afterwards. Join Mike Simpson as he discusses how to use testing and design to “Assure Software Quality.”

Testing is an integral part of assuring software quality. However, determining what tests to perform is as much art as science. What should you test? How should you test? What should you measure in your tests? Join Mike Simpson as he tackles “Software Quality Testing.”

Software quality requires that modifications and additions be thoroughly documented and verified. How do you create, design and verify your tests to assure software quality? Join Mike Simpson as he discusses techniques of “Quality Assurance.”

ISO (International Standards Organization) 9000 certification is an eagerly coveted and yet murky certification that an organization, process or piece of software meets certain quality standards. What does ISO 9000 certification mean for software and how can a company use that certification to its advantage? Join Mike Simpson as he discusses “ISO 9000 Requirements and Their Effect on Software.”

Software quality is an ill-defined term. Yes, everyone wants high-quality software, but how does one define and measure it? Join Mike Simpson as he clears the alphabet soup of “An Overview of Software Quality Assurance.”

Developers often wish to extend the capabilities of a Web server, either by creating custom extensions for a Web server or by creating dynamic Java Server Pages that add automation and animation to static Web pages. Java supports these extensions and dynamism by permitting the creation of small classes, called servlets, that carry out the dynamic behavior of Java Server Pages or accept and process custom input from a Web page. Join Mike Simpson as he explores the power of “Servlets in Java.”

We all want our programs to work well, but sometimes they encounter unexpected situations. Java provides an elegant mechanism for handling single or multiple anomalous situations during program execution. Join Mike Simpson as he shows you how to handle “Exceptions in Java.”

Most of our programs today have to do more than one thing at a time. Java uses threads to carry out simultaneous tasks during a program's execution. Join Mike Simpson as he weaves his way through “Threads in Java.”

Java can “deflate” the in-memory state of an object to a stream of bytes and use that same stream to “inflate” another copy of the object. This technique of saving an object to disk is known as “serializing” an object. Join Mike Simpson as he details several methods for saving object contents on “Java 6 Object Serialization.”

Many Java applications need to interact with disk files – reading information from files and writing information to files. Java 6 has added file-permission testing and manipulation features, and file system space features, to an already-rich collection of file access and file manipulation methods. Join Mike Simpson as he explains the existing and new features of “Java 6 File I/O.”
