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.
