Scott Davis
Author of "Groovy Recipes"
Scott published one of the first public websites implemented in Grails in 2006 and has been actively working with the technology ever since. Author of the book Groovy Recipes: Greasing the Wheels of Java and two ongoing IBM developerWorks article series (Mastering Grails and in 2009, Practically Groovy), Scott writes extensively about how Groovy and Grails are the future of Java development.
Presentations
Ajax development with the Yahoo! UI Library and Grails
Yahoo! is a company that eats its own dog food. They open sourced the Ajax code that drives many of their own websites, including their eponymous homepage, Yahoo! Mail, and Yahoo! News. Come see first hand how the various pieces of the library work together as a seamless whole.
We'll look at some of the everyday useful widgets like the onscreen JavaScript logger (which effectively brings Log4J-style logging to JavaScript) and the calendar components. We'll see how event handling is managed in a cross-brower fashion. We'll look at tabbed interfaces, multi-level menus, and panels and dialog boxes that end up making your website look more like a OS-level desktop than a traditional webpage.
The YUI library is included with the Grails web framework. It certainly works in all of the major frameworks as well, but the easy bootstrapping of Grails combined with the power of YUI library makes for the quickest way to get started with a minimum of hassle. No previous Groovy or Grails experience is required, so come to learn a little about all of these. Any experience JEE developer will feel right at home since Grails uses Spring and Hibernate under the covers.
Workshop #3: GIS for Web Developers
Based on the book GIS for Web Developers, this talk demonstrates how you can build your own Google Maps in-house using nothing but open source software. We also discuss integrating free, public domain data from sources like the US Census Bureau and the USGS. If you're looking for real-world examples of AJAX in use, you'll find it here. If you're looking for real-world examples of web services in use, you'll find it here.
We'll start by exploring free datasets out there in the wild. They are stored in a myriad of file formats (some proprietary, some open) and projections. Free tools like GDAL and QGIS make it easy to convert them and visualize them. Once the data is normalized, we'll store it in a PostgreSQL/PostGIS database. Not only does the database centralize the mapping data, it opens up quite a few interesting querying capabilities.
Serving up the data is the final piece of the puzzle. We'll look at web services based on the OGC (Open Geospatial Consortium) standards. We'll use Tomcat and the GeoServer WAR to expose our data via OGC interfaces. We'll look at a couple of Ajax-based mapping frameworks (MapBuilder and OpenLayers) that truly bring the power of a Google Maps-like website to your own in-house application.
If you've had no previous mapping experience, this talk breaks the domain down into easy to understand concepts. You'll come out with a better understanding of the challenges and rewards of hosting your own web mapping infrastructure.

Each recipe in Groovy Recipes begins with a concise code example for a quick start, followed by in-depth explanation in plain English. These recipes will get you to-to-speed in a Groovy environment quickly.
You'll see how to speed up nearly every aspect of the development process using Groovy. Groovy makes mundane file management tasks like copying and renaming files trivial. Reading and writing XML has never been easier with XmlParsers and XmlBuilders. Breathe new life into Arrays, Maps, and Lists with a number of convenience methods. But Groovy does more than just ease traditional Java development: it brings modern programming features to the Java platform like closures, duck-typing, and metaprogramming.
As an added bonus, this book also covers Grails. You'll be amazed at how quickly you can have a first-class web application up and running from ground zero. Grails includes everything you need in a single zip file⎯a web server (Jetty), a database (HSQLDB), Spring, Hibernate, even a Groovy version of Ant called GANT. We cover everything from getting a basic website in place to advanced features that take you beyond HTML into the world of Web Services: REST, JSON, Atom, Podcasting, and much much more.

There is a hidden revolution going on: geography is moving from niche to the mainstream. News reports routinely include maps and satellite images. More and more pieces of equipment cell phones, cars, computers now contain Global Positioning System (GPS) receivers. Many of the major database vendors have made geographic data types standard in their flagship products.
GIS for Web Developers introduces Geographic Information Systems (GIS) in simple terms and demonstrates hands-on uses. With this book, you'll explore popular websites like maps.google.com, see the technologies they use, and learn how to create your own. Written with the usual Pragmatic Bookshelf humor and real-world experience, GIS for Web Developers makes geographic programming concepts accessible to the common developer.
This book will demystify GIS and show you how to make GIS work for you. You'll learn the buzzwords and explore ways to geographically-enable your own applications. GIS is not a fundamentally difficult domain, but there is a barrier to entry because of the industry jargon. This book will show you how to "walk the walk" and "talk the talk" of a geographer.
You'll learn how to find the vast amounts of free geographic data that's out there and how to bring it all together. Although this data is free, it's scattered across the web on a variety of different sites, in a variety of incompatible formats. You'll see how to convert it among several popular formats including plain text, ESRI Shapefiles, and Geography Markup Language (GML).
With this book in hand, you'll become a real geographic programmer using the Java programming language. You'll find plenty of working code examples in Java using some of the many GIS-oriented applications and APIs. You'll be able to:
Find free sources of GIS data on the web Browse GIS data using open source desktop viewers Manipulate GIS data programmatically Store and retrieve data using geographically-enabled databases Explore free web toolkits like Google Maps Publish and consume web services using Open Geospatial Consortium (OGC) interfaces
