Creator of Apache Tapestry

Howard Lewis Ship is the original creator of the Apache Tapestry project, and is a noted expert on Java framework design and developer productivity. He has over twenty years of full-time software development under his belt, with over fifteen years of Java. He cut his teeth writing customer support software for Stratus Computer, but eventually traded PL/1 for Objective-C and NeXTSTEP before settling into Java.

Howard has been developing financial and e-commerce applications in 100% Clojure since 2012.

Howard currently works for Wal-Mart's Global E-Commerce division. He lives in Portland, Oregon with his wife Suzanne, and his children, Jacob and Olivia.

Presentations

Clojure Workshop

3:15 PM MDT

In an increasingly crowded field of languages, Clojure stands alone. It is a dynamic, functional, high performance dialect of Lisp that runs on both the JVM and CLR. The creator cast aside assumptions from both the Lisp and Java communities to create a remarkable language implementation.

This workshop introduces Clojure to Java developers who might not have seen a Lisp and don’t yet understand why that’s such an advantage. I introduce the language syntax (what little there is of it), cover interoperability with Java, macros, mutlti-methods, and more. I also cover the functional aspects of Clojure, showing its powerful immutable data structures, working with threads and concurrency, and sequences. Beyond just showing syntax, I also show how to build real applications in Clojure, and give you a chance to do the same. Attending this workshop shows enough to pique your interest and show why many of the people who were interested in Java in 1996 are interested in Clojure now.

Tapestry in Action (In Action series)

Tapestry in Action (In Action series)

by Howard M. Lewis Ship

The creator of Tapestry details how to use this new framework's components to create rich web-based GUIs using links, images, and HTML forms. The challenges of web application development are discussed, such as managing server-side state properly, application localization, and maintaining synchronization between the client web browser and the application server. At the same time, the benefits of a clean separation between presentation logic and business logic and how well Tapestry succeeds in keeping these two concerns apart are identified. Written for new Tapestry users and even developers new to creating web applications in general, this guide includes extensive notes on development ""gotchas,"" including common Tapestry errors and how to fix them. Advanced techniques are covered as well, including creating entirely new components, integration with traditional servlet and JSP applications, and creation of client-side JavaScript. Finally, a complete J2EE application, the Virtual Library, is presented and analyzed in detail.
