title: Some Tomcat webapps not opening
body: <p>I downloaded a couple of webapps and placed them in my /webapps folder.
  Some of them I could open by going to <code>http://localhost:8080/app1</code> and it would open.
  However, some others I would do the exact same thing and go to <code>http://localhost:8080/app2</code> and it will display "HTTP Status 404 - /app2/", even though I am sure it is there.  I've checked that it contains a WEB-INF folder just like app1, and I've even restarted Tomcat to be sure.</p>
  
  <p>My question is: is there anything (perhaps in the web.xml file) that specifies what the URL has to be to start the webapp? Or is it simply just <code>http://localhost:8080/&lt;folder name&gt;</code> ?</p>
  
  <p>P.S. If you want to know exactly what app1 and app2 I am refering to:
  app1 (works) = <a href="http://assets.devx.com/sourcecode/11237.zip" rel="nofollow noreferrer">http://assets.devx.com/sourcecode/11237.zip</a>
  app2 (doesn't work) = <a href="http://www.laliluna.de/download/eclipse-spring-jdbc-tutorial.zip" rel="nofollow noreferrer">http://www.laliluna.de/download/eclipse-spring-jdbc-tutorial.zip</a></p>
  
  <p>I've tried a few others as well, some work, some don't.  I'm just wondering if I'm missing something.</p>
