Scripting in Java: Languages, Frameworks, and Patterns

Dejan Bosanac9780321321930, 0-321-32193-6

Using the JavaTM platform’s new scripting support, you can improve efficiency, streamline your development processes, and solve problems ranging from prototyping to Web application programming. In Scripting in Java, Dejan Bosanac covers key aspects of scripting with Java, from the exciting new Groovy scripting language to Java’s new Scripting and Web Scripting APIs. Bosanac begins by reviewing the role and value of scripting languages, and then systematically introduces today’s best scripting solutions for the Java platform. He introduces Java scripting frameworks, identifies proven patterns for integrating scripting into Java applications, and presents practical techniques for everything from unit testing to project builds. He supports key concepts with extensive code examples that demonstrate scripting at work in real-world Java projects. Coverage includes
