Description

While running a simple test with a buildr-scala-JERSEY-JETTY setup, the java process is forking, such that printlns are not going to the console the process was started in, and killing that process does not kill the jetty server. It's certainly not a blocker, but it is annoying.

Here's the buildfile (sorry I can't attach it as a file to download for the issue):
***************************************************************************
require 'buildr/scala'

repositories.remote << 'http://www.ibiblio.org/maven2'
repositories.remote << 'http://download.java.net/maven/2'
repositories.remote << 'http://download.java.net/maven/glassfish'

SERVLET = ['org.glassfish:javax.servlet:jar:3.0','javax.persistence:persistence-api:jar:1.0']
JERSEY = ['com.sun.jersey:jersey-json:jar:1.8','com.sun.jersey:jersey-server:jar:1.8','com.sun.jersey:jersey-core:jar:1.8','com.sun.jersey:jersey-bundle:jar:1.8']
JETTY = ['org.eclipse.jetty:jetty-continuation:jar:8.0.0.M0','org.eclipse.jetty:jetty-security:jar:8.0.0.M0','org.eclipse.jetty:jetty-http:jar:8.0.0.M0','org.eclipse.jetty:jetty-io:jar:8.0.0.M0','org.eclipse.jetty:jetty-util:jar:8.0.0.M0','org.eclipse.jetty:jetty-server:jar:8.0.0.M0','org.eclipse.jetty:jetty-servlet:jar:8.0.0.M0']
ASM = ['asm:asm-all:jar:3.3.1']

VERSION_NUMBER = '0.1'
GROUP = 'test'

define "testproject" do
project.version = VERSION_NUMBER
project.group = GROUP
compile.with ASM,SERVLET,JERSEY,JETTY

task :run => :compile do
puts('Starting up with classpath ' + compile.dependencies.to_s + " " + [compile.target.to_s].to_s)
Java::Commands.java('launcher.MyServer', :classpath => compile.dependencies + [compile.target.to_s])
end

package(:jar).with :manifest=>manifest.merge('Main-Class'=>'launcher.MyServer')

end

***************************************************************************
Here is launcher.scala:

package launcher

import javax.servlet.http.

{HttpServletRequest, HttpServletResponse}

import javax.servlet.ServletException

import java.io.IOException

import org.eclipse.jetty.server.

{Server, Request}

import org.eclipse.jetty.server.handler.AbstractHandler
import org.eclipse.jetty.server.nio.SelectChannelConnector
import org.eclipse.jetty.servlet.

{ServletHolder, ServletContextHandler}

import com.sun.jersey.spi.container.servlet.ServletContainer

import javax.ws.rs.

{GET, Produces, Path}

object MyServer {

def main(args: Array[String])

{ System.out.println("Starting up server") val server = new Server(3080) val connector = new SelectChannelConnector() server.addConnector(connector) val holder:ServletHolder = new ServletHolder(classOf[ServletContainer]) holder.setInitParameter("com.sun.jersey.config.property.resourceConfigClass", "com.sun.jersey.api.core.PackagesResourceConfig") holder.setInitParameter("com.sun.jersey.config.property.packages", "com.sample") val context = new ServletContextHandler(server, "/", ServletContextHandler.SESSIONS) context.addServlet(holder, "/*") server.start server.join }

}

*******************************************************************************
And here is com.sample.Ping.scala:

package com.sample

import javax.ws.rs.

{GET, Produces, Path, PUT}

@Path("/")
class PingResource {
@GET
def ping() =

{ "ping" }

@PUT
def ping(input:String) =

{ input }

}
