ok , the easy way :

in your servlet define :

String comment = request.getParameter("preview-form-comment") ;

request.setAttribute("anydata", comment);

and in your textarea write :

 <textarea id="preview-form-comment" name="preview-form-comment">${anydata}</textarea>

it run :) good luck

One way to do this would be using php. I'll post an example below:

<input type="text" placeholder="Your name" name="name" value="<?php if(isset($_POST['name'])){echo $_POST['name'];}?>">

I'm not sure if you know php or not but essentially here's the breakdown. From your html it looks like you're self submitting meaning returning to the same page. So when you post data to the page we can access it using $_POST['name of the field']

That said we can use the isset php method to see if the form has posted data and if it has populate the field with the old value.
