New book on indexing and search

The last book that Erik Hatcher co-authored was a definitive guide on Ant and with "Lucene in action" he has done it again. A couple of summers ago I saw Erik do a Lucene presentation at OSCon. In the back of the room sat a tall quiet man mostly nodding at what Erik was saying. That was Doug Cutting, the man who wrote Lucene. The book is a comprehensive look at indexing with Lucene and Hatcher and his co-author Otis Gospodnetic have done a great job. Check out Erik's Lucene in Action website www.lucenebook.com and we've reprinted his Introduction to Lucene article from July 2003.

In today's Weblogs , James Todd writes that he is presenting "a MyJXTA Overview at PenLUG tomorrow evening. Kind of a short notice but I just finished pulling the presentation together. I like the results and we've needed a doc like this for awhile now.

Also in Also in Java Today , Greg Nudelman's entertaining JavaWorld article explains The timestamp-based caching framework . He sets up the article by writing "When we garbage-collect perfectly good objects, we blunt our weapons and waste precious system resources by re-creating these objects all over again. By implementing a caching framework, we hope that most of our gains resulting from our creation of complex objects will remain intact. If we store completed objects in the cache, we avoid repeatedly re-creating these objects and thus enjoy a boost in application performance."

Those committed to TDD often find that developing GUIs presents obstacles. Santosh Shanbhag helps you navigate some of the standard problems in his article Developing Custom Swing Components With Test Driven Development. He begins by testing the visual layout of a component and then "A GUI test helper class provides useful methods to find components without the need to expose them using accessors in the original class."

In Projects and Communities, the JCP is running an article on our own JSR community titled JCP 2.6 Clears the Way for a New JSR Community on java.net noting " The primary benefit of JCP 2.6 is the transparency it now requires, freeing expert groups to reveal much more about a given Java Specification Request (JSR) as it is being developed."

Now that JDOM has been at version 1.0 for a while, you may want to take it out for a spin. Jeremy Whitlock has written an introduction to XML With JDOM showing you examples of "Parsing XML with JDOM, Authoring XML with JDOM, Writing XML to file with JDOM".

What about a New AWT for Linux. In today's Forums FLozano writes " I want new AWT peer based on GTK, Pango and other Gnome libraries and not on old Motiff anymore, besides following JFreeDesktop.org standards. This would provide a lot of benefits and make Java on Linux desktops viable"

Cowwoc proposes we Unify class customization and construction. "I'd like to propose an alternate syntax for Generics. This is motivated by my belief that although Generics is an important and useful paradigm, its syntax (derived from C++) is really poor and poses a serious readability problem."
