title: Spring Roo: 'web mvc setup' fails with 'display name required'
body: <p>I'm trying to follow the Spring Roo tutorial at: </p>
  
  <pre><code>http://static.springsource.org/spring-roo/reference/html/beginning.html
  </code></pre>
  
  <p>I was able to create entities and pass integration tests.</p>
  
  <p>But, when I move on to create controllers, the following command fails:</p>
  
  <pre><code>roo&gt; web mvc setup
  Created ROOT/src/main/webapp/WEB-INF/spring
  Created ROOT/src/main/webapp/WEB-INF/spring/webmvc-config.xml
  Undo create ROOT/src/main/webapp/WEB-INF/spring/webmvc-config.xml
  Undo create ROOT/src/main/webapp/WEB-INF/spring
  display name required
  </code></pre>
  
  <p>When I move on to the next Roo step, I get the following:</p>
  
  <pre><code>roo&gt; web mvc all --package ~.web
  Command 'web mvc all --package ~.web' was found but is not currently available (type      'help' then ENTER to learn about this command)
  </code></pre>
  
  <p>Any ideas on how to fix these problems? Thank you.</p>
