title: To get multiple checkboxes value
body: <p>I am using Struts 2, JSP and JPA in my project. 
  I have nearly 50 checkboxes in a single page. If i want to get the value of each checkbox in Action class, then i have write 50 getters and setters.
  Is there any easy way to get the values of all checkboxes in Action class.</p>
  
  <p>Thank you,</p>
