As experienced Java developers, Adam Freeman and Allen Jones have followed the progress of C# and .NET with interest from their earliest stages. When the first versions of the language and platform were released, Adam and Allen began learning how to program effectively with C# and how to drive the .NET environment. They are both 12-year veterans of the technology treadmill. Having reinvented themselves numerous times during their careers, Adam and Allen have always stayed toward the leading edge of the technology curve. It is this desire to stay ahead that drove them to seek a deep understanding of first Java and now C#. They have worked together for the last three years, having first met while working as consultants for Marimba, one of the most Java-centric companies ever formed. Most recently they have collaborated on the design and development of a custom J2EE implementation to provide specialized e-commerce infrastructure for the physical oil industry. It is their proven ability to learn, understand, and apply new technologies and concepts and their experience communicating complex ideas to others that make Adam Freeman and Allen Jones the perfect authors for this project.

Adam Freeman has been developing in Java since before its general availability and has contributed to successful Java books and course materials, including Addison Wesley’s Programming the Internet with Java. He has developed many of the largest, most complex, and most innovative Java projects in the world. His recent experience architecting a proprietary J2EE implementation for an e-commerce platform has given him an in-depth understanding of the current technologies and challenges facing those developing large-scale distributed e-commerce systems. Adam has previously worked for Netscape, Sun Microsystems, and the NASDAQ stock exchange.

Allen Jones has spent his career working for large corporate and financial institutions, successfully developing and implementing solutions based on the Microsoft enterprise product range. Allen has been developing Microsoft Windows® solutions since 1990 and working with Windows NT® and Win32® since 1993. He was one of the first MCSEs to qualify anywhere in the world. Allen started programming in Java three years ago and has since been developing e-commerce and security systems. He is a former employee of Microsoft in both Australia and the United Kingdom.
