title: Tomcat 7 is not running on ubuntu 12.04
body: <p>I installed tomcat7, but once I try to log on <code>(http://localhost:8080)</code> using my default browser (firefox) it won't work. </p>
  
  <pre><code>Unable to connect
  Firefox can't establish a connection to the server at `(http://localhost:8080)`.
  </code></pre>
  
  <p>Although when I started it from the terminal # sh startup.sh I get the right messages : </p>
  
  <pre><code>Using CATALINA_BASE:   /usr/local/tomcat7
  Using CATALINA_HOME:   /usr/local/tomcat7
  Using CATALINA_TMPDIR: /usr/local/tomcat7/temp
  Using JRE_HOME:        /usr/local/jdk1.6.0_23/jre
  Using CLASSPATH:       /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar
  
  Tomcat started.
