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.

• 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.

• 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 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.

• Built in Java using the 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)
