Jboss 5.1 in Dockerfile - how to reach the server in a browser - jboss

Question

I have a dockerfile which looks like this:
FROM ubuntu:trusty
RUN DEBIAN_FRONTEND=noninteractive apt-get -yq upgrade
# Update to latest
RUN echo "deb http://archive.ubuntu.com/ubuntu trusty main universe" > /etc/apt/sources.list
RUN echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" > /etc/apt/sources.list.d/webupd8team-java.list
RUN apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C2518248EEA14886
RUN apt-get update
RUN apt-get upgrade -y
# Install basics
# RUN apt-get install -y python-software-properties software-properties-common unzip
RUN apt-get install -y unzip
# Install Java, auto-accepting the license
# RUN add-apt-repository -y ppa:webupd8team/java
# RUN apt-get update
# RUN echo oracle-java6-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections
# RUN apt-get install -y oracle-java6-installer
RUN echo oracle-java6-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections
# Install different Java versions
RUN DEBIAN_FRONTEND=noninteractive apt-get install -yq oracle-java6-installer
# Set environment variables pointing to different Java installations
ENV JAVA_HOME /usr/lib/jvm/java-6-oracle
ENV JAVA6_HOME /usr/lib/jvm/java-6-oracle
# Ensure Java 6 is the default version
RUN update-java-alternatives -s java-6-oracle
# Install JBoss 5.1.0.GA
RUN wget -O jboss.zip http://sourceforge.net/projects/jboss/files/JBoss/JBoss-5.1.0.GA/jboss-5.1.0.GA-jdk6.zip/download
RUN unzip jboss.zip && mv jboss-5.1.0.GA /opt
RUN cd /opt/jboss-5.1.0.GA/bin && chmod +x *.sh
CMD /opt/jboss-5.1.0.GA/bin/run.sh
# Clean-up to reduce the image size
RUN apt-get clean
EXPOSE 8080
i build it than with:
sudo docker build -t dockerfile .
everything builds fine. so I start the server with:
sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest
I can see that the server starts correctly
If I enter the URL 127.0.0.1:8080 i got an error site:
the connection was reset - the connection to the server was reset
while the page was loading
How do I get a connection to the server in my browser?
The inspect of my container looks like this:

EDIT after jottrs answers:
the logs says:
....
11:36:32,963 INFO [TomcatDeployment] deploy, ctxPath=/admin-console

nothing more....
because of Jottrs IP mention:
As far as i understood, I bind my server to 127.0.0.1:8080 with the start command:
sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest
If I look with ifconfig i have the docker file running on:
$ ifconfig
docker0 Link encap:Ethernet Hardware Adresse 56:84:7a:fe:97:99
inet Adresse:172.17.42.1 Bcast:0.0.0.0 Maske:255.255.0.0

Kollisionen:0 Sendewarteschlangenlänge:0
RX-Bytes:4983 (4.9 KB) TX-Bytes:12056 (12.0 KB)
But with $ sudo docker inspect --format "{{ .NetworkSettings.IPAddress }}" 054
i get 172.17.0.5
But I also get no connection in my browser with the URL 172.17.0.5:8080 or URL 172.17.42.1:8080
also if I start with $ sudo docker run -d --publish 172.17.42.1:8080:8080 dockerfile:latest (the ifconfig IP) I will not get a connection (and still no reaction on the logs)
$ sudo docker exec -it 228 bash

172.17.0.6 22870ce4265e
127.0.0.1 localhost

The problem is JBoss not Docker. JBoss listen per default only to localhost:8080 Jboss only works on localhost:8080 ,but doesnt reply when called by ip (I'm not a JBoss guy so you have to try "-b 0.0.0.0" or to provide a server.xml via ADD in your Dockerfile).
When you run (in my case I called the container jboss)
sudo docker exec jboss apt-get install curl -y
sudo docker exec jboss curl localhost:8080
you notice that JBoss runs and is accessable.
