RealClassLoader from classworlds.

Sure.
main is br.com.ibnetwork.e2.loader.E2Loader from e2loader
[e2loader]
load ${app.home}/bin/classes/common/
load /usr/share/jars/servletapi-2.3.jar
[phoenix]
import br.com.ibnetwork.e2.loader.Startable from e2loader
load ${app.home}/bin/classes/phoenix/
load ${phoenix.home}/bin/phoenix-loader.jar
load ${xingu.home}/xingu-container-alpha-0.1.jar
[tomcat]
import br.com.ibnetwork.e2.loader.Startable from e2loader
load ${app.home}/bin/classes/tomcat/
load ${tomcat.home}/bin/commons-logging-api.jar
load ${tomcat.home}/server/lib/*.jar
load ${tomcat.home}/common/lib/*.jar
[jetty]
import br.com.ibnetwork.e2.loader.Startable from e2loader
load ${app.home}/bin/classes/jetty/
load ${jetty.home}/lib/*.jar
load ${jetty.home}/ext/jasper-compiler.jar
load ${jetty.home}/ext/jasper-runtime.jar

I want to put my singleton on [e2loader]. But I'm testing it on
[phoenix]. It's placed on xingu-container-alpha-0.1.jar

AFAIK, singletons are unique on each classloader, so, I must use the
same classloader to load it on all my apps, right ?
Both on jetty and phoenix/james.
