Gerald Bauer is an independent Java, XML und Internet consultant supporting Open Source Software. Gerald studied at the Wirtschaftsuniversitaet Wien und der New York University and currently leads the Luxor Projekt - an Apache licensed XML User Interface Language (XUL) Toolkit in Java. He supports the new XML UI Language (XUL) Standard for the next generation browser for the Open XULAlliance Initiative ("A Rich Internet For Everyone").

Gerald introduces you to Groovy, a free, open-source scripting language in Java for the Java runtime that borrows the best from dynamic languages like Python, Ruby or Smalltalk and offers it to you in an all-in-one package using a Java-style syntax. Groovy compiles straight to Java bytecode on-the-fly and works out-of-the-box with all existing Java objects and libraries. Groovy offers higher-level functions and abstract iterators (=closures), built-in syntax for lists and maps, markup (XML), regular expressions (regex), ranges, and much much more.
