title: Multiple method calling using single servlet
body: <p>I am new to JavaEE and have a query regarding a servlet that has multiple methods. </p>
  
  <p>I want to know how I can call a specific method on a servlet, when I click "<code>Submit</code>" button in JSP.?</p>
  
  <p>Someone have suggested to use <code>HTML hidden fields</code> but I have no idea on how to implement them in Jsp.</p>
