Scripting in Java

Scripting in Java covers the new Java Script API (not JavaScript) in Java 8 that enables Java applications to execute scripts written in scripting languages such as Rhino JavaScript, Groovy, JRuby, Jython and more. Although the Java Script API was introduced in Java 6 and has been enhanced in the new Java 8 release. This book is not for learning a scripting language such as Rhino JavaScript, Groovy, etc.§§Rather, it is for learning how to use the Java Script API to execute scripts written in a scripting language and takes advantage of the features of a scripting language while developing Java applications. The book also covers topics that enable scripting languages to take advantage of the Java programming language features and the Java class library, including the new Java Collections and JavaFX 8 APIs. Most of the examples in this book use Rhino JavaScript. Scripts in Groovy and Rhino JavaScript compare and contrast support for Java features by these two scripting languages. Some of the examples use the jrunscript and jjs command-line tools.§§Furthermore, debugging is discussed when or if you encounter any issues with this kind of Java scripting when deployed. After reading and using this book, you should be able to have most of what you need to do scripting in Java.§§
