The Busy Java Developer's Guide to Scala: Scala + Services
Scala is a new programming language incorporating the most important concepts of object-oriented and functional languages and running on top of the Java Virtual Machine as standard “dot-class” files. Sporting the usual object-oriented concepts as classes and inheritance, Scala also offers a number of powerful functional features, such as algebraic data types, immutable objects by default, pattern matching, closures, anonymous functions and currying, and more. Combined with some deep support for XML generation and consumption, Scala offers Java programmers an opportunity to write powerful programs with concise syntax for a new decade of Java programming.
In this presentation, we take the Scala language, its support for XML, it's immutable and functional approaches, and build a simple XML service with it, no JAX-WS needed (or wanted). Deploying the service as a simple servlet, we show it being consumed from a traditional JAX-WS service client, and from a more “hip” REST approach.
