Agenda

Here is what I would like for you to leave understanding:

Overview of Clojure

Interoperability with Java

Leveraging and deploying in JBoss

Clojure is more than...

Well... What Should I Use?

Overview

Overview - Functions

Overview - Exceptions

In REPL

Overview - Exceptions

Overview - Agents

Interop – Java in Clojure

Interop – Clojure in Java

Use gen-class – then no differencehttp://blog.objectmentor.com/articles/2009/08/07/java-calling-clojure

To the Code!

Simple Functions

Build quote assimilation (w/ agent)

Integrate code w/ Java

Build & Deploy to JBoss

Code Break

And we’re back

Getting Started

Get your IDE setup (JBDS, IntelliJ, NetBeans, Emacs)...

Watch some Clojure videos

Play around in a REPL, get used to functional programming

Learn the testing framework

Build up a concurrency app (leveraging web calls is easiest)

Integrate ... Grow
