Spray akka deploy to web server

I have an application built with spray + akka. using this guide:

http://sysgears.com/articles/building-rest-service-with-scala/

This explains the following example: https://github.com/oermolaev/simple-scala-rest-example

The app works fine. But when trying to deploy to a web server, I couldn't find a way to do this.

I tried to use xsbt-web-plugin to deploy to Tomcat, got the following input:

 ~container:start

[info] starting server ... Adding context for target / webapp ...

Starting Tomcat Service Starting Servlet:

Apache Tomcat / 7.0.34 org.apache.catalina.startup.ContextConfig

getDefaultWebXmlFragment INFO: Global web.xml not found

org.apache.coyote.AbstractProtocol start INFO: Start

ProtocolHandler ["http-nio-8080"]

But Tomcat returns 404 for all requests.

Does anyone know how I can deploy akka spray application to Tomcat?

Solved a problem.

This is what you need for the xsbt-plugin to work with your spray application:

  • Set root-path

    in application.conf

As @jrudolph explained: serpentine doesn't know to figure it out automatically on tomcat:

spray.servlet {
   boot-class = "com.sysgears.example.boot.Boot"
   root-path = "/rest"
   request-timeout = 10s
 }
  1. Modify the class boot

    to extend webBoot

    :


boot.scala

class Boot extends WebBoot {
  // create an actor system for application

  val system = ActorSystem("rest-service-example")

  // create and start rest service actor

  val serviceActor = system.actorOf(Props[RestServiceActor], "rest-endpoint")
}

  1. add web.xml as described in xsbt-web-plugin:

    Src / main / webapp / WEB-INF / web.xml:

    <listener>
    <listener-class>spray.servlet.Initializer</listener-class>
</listener>

<servlet>
    <servlet-name>SprayConnectorServlet</servlet-name>
    <servlet-class>spray.servlet.Servlet30ConnectorServlet</servlet-class>
    <async-supported>true</async-supported>
</servlet>

<servlet-mapping>
    <servlet-name>SprayConnectorServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

For a complete change, see the comparison on github (sample script generously generates this thread for tomcat users)
