title: close pop up window and redirect to parent window in struts2
body: <p>I have pop up window , in which to upload an excel file of adding new users.
  After clicking the button and successfully added the users into DB, I want to close the pop up window and refresh the parent window to see the updates. In Parent Window, it shows the list of users.</p>
  
  <p><em><strong>How can I handle all of these events and steps in Struts2 and javascript?</em></strong></p>
  
  <pre><code>function callAddUsers() {
              document.frmUpload.action = "addUsers.action";
              document.frmUpload.submit();
              } 
  </code></pre>
  
  <p>I want to display some messages of how many users added in parent window too. How can I pass all those info by action?</p>
  
  <p><em>Now the problem is when I successfully uploaded and added users, the popup window displays the list of users and I have two window opened.</em></p>
  
  <p>Thanks.</p>
