<input type="submit" onclick="importScenarioFromServer();">
</form>

javascript:

function importScenarioFromServer(){
    var result = document.forms["importForm"].submit();
}

servlet:

int numberOfRecs = db.setDBValue(dMap);
if (numberOfRecs == 1) {
String result = "success";
response.getWriter().print(result);
}

Use ajax if you don't want to refresh the page, for this JQuery#ajax will come in handy. — user2575725

This can be implemented using ajax either in javascript or by using jquery. we can serialise form in ajax hit and then can get response data from servlet in success event callback function. below is example...

function getData()
{
var client;
var data;
var url_action="/temp/getData";
if(window.XMLHttpRequest)
{
    client=new XMLHttpRequest();
}
else
{
    client=new ActiveXObject("Microsoft.XMLHTTP");
}
client.onreadystatechange=function()
{
    if (client.readyState==4 && client.status==200)
    {
         document.getElementById("response").innerHTML=client.responseText; 
    }
};
data="name="+document.getElementById("name").value+"&file="+document.getElementById("filname").value;
client.open("POST",url_action,true);
client.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
client.send(data);
}


Servlet post method

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    PrintWriter out=response.getWriter();
    log.info("Good");
    out.println("Good to go");
}
