I have a dockerfile which looks like this:
FROM ubuntu:trusty
RUN DEBIAN_FRONTEND=noninteractive apt-get -yq upgrade

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

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?

EDIT after jottrs answers: the logs says:
....

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

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
root@22870ce4265e:/# cat /etc/hosts
172.17.0.6 22870ce4265e

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)
you notice that JBoss runs and is accessable.
