> nothing appears to be listening on the HTTP port.
> Steps:
> * download apache karaf 4.2.4
> * tar xvzf ~/downloads/apache-karaf-4.2.4.tar.gz
> * cd apache-karaf-4.2.4/bin/
> * ./karaf
> * karaf@root()> feature:list -i # shows that feature is not installed
> * karaf@root()> feature:install http # installs http feature
> * karaf@root()> feature:list -i # shows feature installed
> {quote}{\{karaf@root()> feature:list -i }}
