Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Java™ Web Services is a European ibex. The European ibex, also called the Alpine ibex, is a wild goat that lives in the central and southern European Alps. The mammal used to be common in high altitudes of the Alps, but is now a rare and protected species. Male ibexes are distinguished by their long, semicircular horns, which can grow as long as 30 inches. When threatened, ibexes fight with their horns or hide in rocky areas.

The ibex has played a prominent role in Alpine life for thousands of years. Archeologists document 13,000-year-old paintings of ibexes in French caves that depict the animal as a hunting target. Alpine folklore, in which ibex body parts were considered powerful, also popularized hunting of the animal. Until the 18th century, the European ibex lived throughout the Austrian, French, Italian, and Swiss Alps and was hunted extensively. Within the next 200 years, the ibex's habitat shrunk considerably, and herds were found only in northern Italy. Government protection and reintroduction efforts have expanded its habitat in recent decades. Ironically, hunting has also contributed to the recovery of the ibex population in Europe; the animal was reintroduced specifically as a trophy game animal in several Alpine regions, and international hunting expeditions (which feature the ibex and other local wildlife) are now an important source of income for many local populations. Ann Schirmer was the production editor and copyeditor for Java™ Web Services. Matt Hutchinson proofread the book. Claire Cloutier, Jeff Holcomb, and Matt Hutchinson provided quality control. David Chu, Phil Dangler, Julie Flanagan, Sue Willing, and Leanne Soylemez provided production assistance. John Bickelhaupt wrote the index.

Emma Colby designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font.

Melanie Wang designed the interior layout, based on a series design by David Futato. Neil Walls converted the files from Microsoft Word to FrameMaker 5.5.6 using tools created by Mike Sierra. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSans Mono Condensed. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read using Macromedia FreeHand 9 and Adobe Photoshop 6. The tip and warning icons were drawn by Christopher Bing. This colophon was written by Ann Schirmer.
