Set the action attribute of your form to a URL mapped to your servlet and also add a method="post" attribute to your form. That way when user is going to click on the submit button the form will get posted to the servlet. In the servlet you can use response.getParameterValues("fruits") to retrieve the values and process the way you want. After processing you may forward to the same JSP or a new JSP.

Please also go through this ( article to know more about servlet mapping.
