Requirements

spray-server 0.9.0 depends on:

• Scala 2.9.1
• Akka 1.2 or 1.3.x
• parboiled 1.0.2
• mimepull 1.6
• concurrentlinkedhashmap 1.2

spray-client 0.9.0 depends on:

• Scala 2.9.1
• Akka 1.2 or 1.3.x
• parboiled 1.0.2
• mimepull 1.6
• spray-can 0.9.3

If you'd like to use one of the following features you need to supply the respective dependencies as well:

• SprayJsonSupport: spray-json
• LiftJsonSupport: lift-json
• TwirlSupport: twirl-api (provided by sbt-twirl)
• ScalateSupport: [scalate-core]

For maximum compatibility with your specific environment spray does not come with a hard dependency on any particular Akka version. Rather the dependency on Akka is marked as provided, which means that you can (and must) pull it in yourself.
spray-server and spray-client only use the akka-actor module and do not depend on akka-http or any other akka module.

You can run your spray-server application in any of the following web servers / containers:

• Any Servlet 3.0 compatible servlet container (Jetty 8, Tomcat 7, GlassFish 3, etc.)
• Jetty 7
• Tomcat 6
• spray-can

In principle spray-server can work with any web server supporting asynchronous request handling, i.e. it's not bound to servlet containers (spray-can for example is not a servlet container). All that is required to support another server is a very thin glue layer. If you'd like to run spray with a server that is not listed above please ask for support on the mailing list.
