title: Object array to char array
body: <p>I am passing a char array ab[][] from serlet1 to ABC.jsp by:
  <code>request.setAttribute("grid", ab);</code></p>
  
  <p>After I retrieve it in <code>ABC.jsp</code>:
  <code>Object [][] array = request.getAttribute("grid");</code>
  How do I convert it to char array?</p>
  
  <p>I can't find examples of objectToChar or other ways.</p>
