scala - Lift RestHelper don't receive my request -

-

i tried create simple resthelper "hello world" example i'm having trouble. when start container container:start command, 

serve {     case nil _ => extraction.decompose("hello restful world!")   }

is not invoked in resthelper extension. following message: "the requested url / not found on server"

so, seems reason lift ignores 

liftrules.statelessdispatch.append(service)

line in bootstrap.boot.boot definition. , have absolutely no clue why happens.

here's boot class:

package bootstrap  import net.liftweb.http.liftrules import com.yac.restfultest.service  class boot {   def boot {     liftrules.statelessdispatch.append(service)   } }

and here's service:

package com.yac.restfultest  import net.liftweb.http.rest.resthelper import net.liftweb.json.extraction  object service extends resthelper {    serve {     case nil _ => extraction.decompose("hello restful world!")   }  }

and in case helps here's web.xml:

<!doctype web-app system "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app>     <filter>         <filter-name>liftfilter</filter-name>         <display-name>lift filter</display-name>         <description>the filter intercepts lift calls</description>         <filter-class>net.liftweb.http.liftfilter</filter-class>     </filter>     <filter-mapping>         <filter-name>liftfilter</filter-name>         <url-pattern>/*</url-pattern>     </filter-mapping> </web-app>

and in case of above not enough here build.sbt:

name := "testrest"  version := "1.0"  scalaversion := "2.11.6"  resolvers ++= seq("snapshots" @ "https://oss.sonatype.org/content/repositories/snapshots",   "releases" @ "https://oss.sonatype.org/content/repositories/releases" )  jetty()  librarydependencies ++= {    val liftversion = "2.6.2"    seq(     "net.liftweb" %% "lift-webkit" % liftversion % "compile"   )  }

as can see it's minimalistic lift project setup possible. still can't working. appreciated.

and here's sbt log on container:start:

so, turns out it's usual noobish non-attentiveness. package, containing boot.scala should called bootstrap.liftweb , not bootstrap in case.

and yes, suggested jcern should "index" :: nil in routing pattern.
