## Commons SCXML Guide

This is a collection of notes about all things Commons SCXML, a scratch pad of sorts, aimed at noting down usages for the frequently needed bits of Commons SCXML and some related and interesting (to some of us) tidbits.

### Introduction

State Chart XML (SCXML) is a general-purpose event-based state machine language that can be used in many ways.

- SCXML documents - A five minute introduction to SCXML documents.
- Commons SCXML - Using the Commons SCXML engine.

### Trying out Commons SCXML

Contains notes about trying Commons SCXML and testing SCXML documents.

- Standalone - Rev'ing the engine.

### Core API

Contains notes about the core Commons SCXML APIs.

The first set of notes walks through the most common usage pattern, end-to-end.

- Digester - Digesting SCXML into the Commons SCXML Java object model.
- Datamodel - Defining a datamodel and temporary variables.
- Contexts and Evaluators - Plugging in the expression language for the document.
- Executor - Instantiating an SCXML executor (engine).
- Triggering events - Executing the event driven state machine.

### Advanced API

Contains notes about Commons SCXML APIs for extending or altering document semantics.

- Custom actions - Adding custom actions to the Commons SCXML object model.
- Custom semantics - Changing the default semantics of the Commons SCXML engine for specialized uses.

### Side-effects

Contains notes about non-primary uses for Commons SCXML.

- EL - Trying Commons EL outside a servlet container.
