Deployment "WebServer" is in error due to the following reason (s): LifecycleException: Protocol handler initialization failed: java.net.BindException: Address already in use: JVM_Bind localhost / 127.0.0.1: 8080, ERROR Deployment "jboss.web: service = WebServer" is in error due to the following reason (s): ** NOT FOUND Depends on 'jboss.web: service = WebServer' **
It seems that the port on which you are raising JBoss is already in use (If you are on Windows, Skype has a bad habit of occupying it).
You can modify the port to which JBoss is associated to avoid this problem, or stop the process that is using that port.
For the second, using the command (in windows)
netstat -a -n -o
You can check which ports are occupied by which processes (with the PID, you can search your process in the task manager).
For the first thing, you should look for your port in the configuration file (if you throw with the default configuration it is the standalone.xml), but normally the eclipse itself allows you to change this data in the configuration of the server.
