title: Get HTML element using JSP
body: <p>I am new to Java EE.  In my application, I have a HTML page containing a text area filled with some information. 
  I also have a form for the user. Once he submits the form, I use a servlet to process the information. 
  Finally I need to forward the Result from the servlet to the same HTML page and update it in the existing textarea. 
  I have done creation of HTML page, submitted the form to servlet. 
  I am now stuck on how to access the textarea in the HTML page to update my result. </p>
  
  <p>I googled a lot but everywhere people forward the result of servlet to JSP page and create a fresh HTML page using "out" object. </p>
  
  <p>I need to use the same textarea of my HTML page to update the result.  Please help me on achieving this. </p>
  
  <p>Thanks in advance. </p>
