Using ajax (using jQuery.ajax, you could make a request to server, In your case may be to a Servlet which will invoke method on server that you requested

For example:

function callMe(){
    $.ajax({
      type: "POST",
      url: "/someServlet",
      data: { methodToInvoke: "sayHello" , data: "Abc" }
    }).done(function( msg ) {
      alert( "Data Saved: " + msg );
    });
}

at Servlet end

doPost(...){
 String methodToCall = request.getParameter("methodToCall");
 //do some stuff to determine method to call and call it like
 methodService.invoke(request.getParameter("data"));
}

you cannot do this directly because JSP is server side and html is client side. However, it can be accomplished via AJAX. http://en.wikipedia.org/wiki/Ajax_(programming)
