title: How to update a .war in Tomcat
body: <p>I am new to Tomcat and following is the steps I am using to update a .war in Tomcat: </p>
  
  <ol>
  <li>stop tomcat.</li>
  <li>delete .war and the folder with same name in /webapps.</li>
  <li>copy and paste my new .war in /webapps.</li>
  <li>restart tomcat by ./bin/catalina.sh run.</li>
  </ol>
  
  <p>However, the new .war always won't work. Seems it's the old version .war that is running. </p>
  
  <p>In /conf/server.xml, I am using the following configs:</p>
  
  <pre><code>  &lt;Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true"&gt;
  </code></pre>
  
  <p>Can someone help me on this problem? Thanks!</p>
