I am not a java developer and perhaps you need to break your question down to two parts.  One for the back end and one for the front.

On the front end, you want to use an ajax request to your back end page.

You can do this in pure javascript, I like to  use jquery
http://api.jquery.com/jquery.ajax/
$.ajax({
  method: "GET",   
  url: "processpage",
  data: { first: "hello", last: "world" }
})
  .done(function( data) {
    alert( data);
  });

Open in new window


On your processpage, accept the get just as if the page was processpage?first=hello&last=world

On your main page, make a page using code similar to what I have above
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-2.0.3.js"></script>
  <script>
    $(function(){
    $.ajax({
  method: "GET",   
  url: "processpage",
  data: { first: "hello", last: "world" }
})
  .done(function( data) {
    //alert( data);
      $('#results').html(data);
  })
    
});
  </script>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>test</title>
</head>
<body>
  <div id="results"></div>
</body>
</html>

Open in new window

When you run the code on the main page above and your other page called processpage can extract the url processpage?first=hello&last=world and output "hello world" you will see that text in the div id results.

How you connect to your database in your java page is another process.

If this makes sense you are good to go.  If not, take just one piece at a time before going on to the next.
