$("#datebutton").click(function(e){              fromdate = $("input#fromdate").val();             todate = $("input#todate").val();             fromcurr = $("input#fromcurr").val();              tocurr = $("input#tocurr").val();              var datastring = "fromdate=" +fromdate+"&todate="+todate+"&fromcurr="+fromcurr+"&tocurr="+tocurr;             $.ajax({                 type: "post",                 url: "getdailyrates.html",                 data: datastring,                 datatype: "text",                 async: 'false',                 success: function(data, textstatus, jqxhr){                     alert("in success");                     $('#display').html("");                      $('#display').append(data);                 },                 error: function(){                     alert("error!");                 }             });            });

java method

@requestmapping(value = "/getdailyrates.html", method = requestmethod.post)     public string getdailyrates(httpservletrequest request, httpservletresponse response ) {          dailyratesquery dailyrate= new dailyratesquery();         string fromcurr= request.getparameter("fromcurr");         string tocurr= request.getparameter("tocurr");          string fromdate= request.getparameter("fromdate");          string todate=request.getparameter("todate");          dailyrate.setfromcurr(fromcurr);         dailyrate.settocurr(tocurr);         dailyrate.setfromdate(fromdate);         dailyrate.settodate(todate);           system.out.println("from currency: "+fromcurr+" currency: "+tocurr+                 " fromdate: "+fromdate+" todate: "+todate);           list<dailyrate> rates = jdbcratedao.getdailyrates(dailyrate);           system.out.println("before return new model");         system.out.println(rates.tostring());         return rates.get(0).tostring();      }

update:

when click button javascript function mapped to, java method have posted called , generates correct output. no sending output jsp.

(both training , prediction can done in parallel, since problems assumed ...
