title: Group Id and package name in Eclipse java web application using maven
body: <p>I plan to create a java web application project in Eclipse using 
  <code>maven-archetype-webapp</code>. Suppose the project will have two packages:</p>
  
  <ol>
  <li><code>com.joe.config</code></li>
  <li><code>com.joe.site</code></li>
  </ol>
  
  <p>What should I put in the <code>"Group Id"</code> and <code>"package"</code> when I create the project? </p>
  
  <p>Should I input <code>com.joe</code> as the Group Id? If so, what should I put in the package section? </p>
  
  <p>(When I type in the <code>"group id"</code> and <code>"artifact id"</code>, the package section automatically combine <code>GroupId</code> and <code>artifact</code>).</p>
