title: InstallTask not found
body: <p>I'm going through the Spring MVC tutorial. I have a build.xml and build.properties file as well as a simple jsp file. When I try to run ant, I get this error:</p>
  
  <pre><code>Buildfile: /&lt;home&gt;/dev/Spring/springapp/build.xml
  
  BUILD FAILED
  /&lt;home&gt;/dev/Spring/springapp/build.xml:85: taskdef class org.apache.catalina.ant.InstallTask cannot be found
  using the classloader AntClassLoader[/usr/local/apache-tomcat/current/lib/catalina-ant.jar]
  
  Total time: 0 seconds
  </code></pre>
  
  <p>I looked in the catalina-ant.jar file, and sure enough there is no InstallTask class. Did this jar file change, since the spring tutorial was written? If so, where can I find the InstallTask.</p>
