Martin Donnelly, Mark Wallace, and Tony McGuckin have written the definitive programmer's guide to utilizing this breakthrough technology. Packed with tips, tricks, and best practices from IBM's own XPages developers, Mastering XPages brings together all the information developers need to become experts - whether you’re experienced with Notes/Domino development or not. The authors start from the very beginning, helping developers steadily build your expertise through practical code examples and clear, complete explanations. Readers will work through scores of real-world XPages examples, learning cutting-edge XPages and XSP language skills and gaining deep insight into the entire development process. Drawing on their own experience working directly with XPages users and customers, the authors illuminate both the technology and how it can be applied to solving real business problems.

Martin Donnelly previously led a software startup that developed and distributed small business accounting software. Donnelly holds a Commerce degree from University College Cork and an M.S. in Computer Science from Boston University.

Mark Wallace has worked at IBM for 15 years on many projects as a technical architect and application developer.

Tony McGuckin participates in the Lotus OneUI Web Application and iWidget Adoption Workgroup. He holds a bachelor's degree in Software Engineering from the University of Ulster.

Meet the Author

The authors of this book have a number of things in common. All three hail from Ireland, work for the IBM Ireland software lab, and have made significant contributions to the development of XPages over the past number of years.

Martin Donnelly is a software architect and technical lead for the Domino Designer and XPages teams in IBM Ireland. He has worked on all XPages releases to date and also on a precursor technology known as XFaces. Martin was also a development contributor to such products as the IBM Java Visual editor and IBM Rational Application Developer. In the 1990s while living and working in Massachusetts, Martin was a lead developer on Domino Designer; this has now gone full circle as he rejoined the Domino Designer team in 2013 to head up the 9.0.1 release. Martin lives in Cork with his wife Aileen, daughters Alison, Aisling, and Maeve, and retired greyhounds Evie and Chelsea. Outside of work his main leisure time pursuits are soccer, fishing, and gardening.

Mark Wallace is a software architect in the IBM Ireland software lab. In the past, he worked on the XFaces runtime, which was developed for Lotus Component Designer and subsequently evolved into the XPages runtime. He has a keen interest in programming models and improving developer productivity. Mark has worked in Lotus and IBM for more than 17 years on various products, and he is currently leading the Social Business Toolkit open source project. Mark lives in Dublin with his wife and two children and spends as much time as possible in the Ireland’s sunny south east enjoying fishing and kayaking with his family.

Tony McGuckin is a senior software engineer in the IBM Ireland software lab. Having studied software engineering at the University of Ulster, he began his career with IBM in 2006 and joined the XPages core runtime team shortly thereafter. When not directly contributing to the core runtime, Tony is busy with software research and development for the next generation of application development tooling, most recently focusing on mobile and responsive design. Tony also spends a lot of time directly engaging with IBM customers as an XPages consultant, where he shows his flair for UI development and his deep understanding of application performance. Tony enjoys spending time with his wife and daughter, and getting out into the great outdoors for hill walking and the occasional chance to do some hunting in the surrounding hillsides of his native County Derry.
