title: Tomcat: LifecycleException when deploying
body: <p>I just downloaded the Tomcat 7.0.23 package on my Ubuntu 11.10. </p>
  
  <p>I followed the instructions on a Google API website to <a href="http://code.google.com/apis/chart/interactive/docs/dev/dsl_get_started.html#webapp" rel="noreferrer">deploy their example webapp</a>. It basically consists of <code>jar</code> files placed in the <code>WEB-INF/lib</code> directory and a <code>web.xml</code> file placed in the <code>WEB-INF</code> directory. </p>
  
  <p>Yet the app is not automatically deployed and when trying to <em>force</em> the server to deploy it through the manager gui, I get the following message:</p>
  
  <pre><code>FAIL - Application at context path /myWebApp could not be started
  FAIL - Encountered exception org.apache.catalina.LifecycleException: 
           Failed to start component 
           [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myWebApp]]
  </code></pre>
  
  <p>However, the JSP examples provided with Tomcat do work!</p>
  
  <p>I have the same problem on Tomcat6.</p>
  
  <p>So what did I do wrong ? Is this a permission problem ? (I even try to change the mod of all files to 777).</p>
