Question

I need to send a particular parameters to Servlet from JSP page. E.g: if I click on the Facebook icon on the web page, then I should send “facebook” as parameter to my Servlet and my Servlet will respond according to the parameter received from JSP file or HTML file.

Answer 1

Just wrap the icon in a link with a query string like so

<a href="servleturl?name=facebook"><img src="facebook.png" /></a>

In the doGet() method of the servlet just get and handle it as follows

String name = request.getParameter("name");

if ("facebook".equals(name)) {
    // Do your specific thing here.
}
