====== Spark | Java Flash Server ======

**Project Page** | [[SparkAlpha]]

  * Subversion: [[http://svn1.cvsdude.com/osflash/spark]]
  * License: Currently LGPL
  * Status: Alpha codebase uploaded to svn, best parts to be merged into [[red5]] (0.5-0.7)

===== Overview =====

Spark is a Java server designed to provide various services to Flash clients. Its combines some well established open source projects (Jetty, Spring, OpenAMF, Hibernate, Rhino, Netty2) to form a single server. Its designed to be modular and extensible also so it should be easy to adapt to your needs. 

===Design Goals===

  * Make connecting flash to a java backend easy !
  * Provide quick development environment and simple deployment.
  * Allow flash developers to code on the server without needing to know java.
  * Allow java developers to expose server side application api to flash developers.
  * Allow for quick prototyping and rapid application development.
  * Fix the problems in using hibernate with remoting.
  * Don't re-invent any wheels, look for good existing open source code and intergrate.
  * Evolve. 

===== Features =====

  * Flash remoting with added support for hibernate, remote objects, and js objects.
  * Code remoting services in JavaScript (same syntax as as1) auto reload and compile into Java on the fly.
  * Use [[Spark:E4X]] (ECMAScript for XML) in javascript. (This has been announced by Macromedia as a feature of the next Flex release also)
  * Expose spring beans (java, soap, ejb, other remoting protocols) as remoting services.
  * Run using embedded jetty servlet engine (used for dev) or deploy as war file to any servlet engine. 
  * Wrap remoting methods in AOP db transation interceptor.
  * Open session in view ensures hibernate session for all remoting calls.
  * ScriptDAO: Data access object for RAD, prototyping, and testing from scripts (api needs refining).
  * Image servlet can resize, and convert images on the fly. (optional extra as it depends on ImageMagick)
  * Ant build file to compile java code, generate hibernate mappings, and package war for deployment.
  * Add any mvc / view technologies spring supports to create your website. 

===== Dependencies =====

   * Built in Java using the [[http://www.springframework.org|Spring Framework]] (apache style license)
   * Uses the Rhino JavaScript engine (mpl license)
   * Remoting code extends [[OpenAMF]] (lgpl)
   * Uses JMagick for image transformation. (lgpl)
   * Uses Netty2 for the NIO socket server (apache license)
