Here is a Sample.

This Code is in your JSP

Code:

<form action="Yourservlet?action=ButtonClicked" method="post">

<%-- Your Code Here --@>

<input type="submit" value="   Ok   " />
</form>

This Code is inside Yourservlet.java

Code:

//Inside your servlet
String action = request.getParameter("action");
try{
            if (action.equalsIgnoreCase(null)){
                //Your error Handler
            }else if (action.equalsIgnoreCase("ButtonClicked"))
            { // Here is where the code that will run if the button is clicked
            } else {
              //Your Default operation
            }
} catch (Exception A) {
              //Another Error Handler ^_^ 
}
