if (request.getparameter("print_type") != null) {     string print_type = request.getparameter("print_type").tostring();      if (print_type.contains("1"))//preprinted page     {         session.removeattribute("default_selected_opd_ticket");         session.setattribute("default_selected_opd_ticket", "1");          if (session.getattribute("opdticket_preprinted") != null) {             printpg = session.getattribute("opdticket_preprinted").tostring();         } else if (print_type.contains("3"))//preprinted page         {             session.removeattribute("default_selected_opd_ticket");             session.setattribute("default_selected_opd_ticket", "3");             printpg = "../opdreport/antenatal_report.jsp";          }      } else {  //for blank page         session.removeattribute("default_selected_opd_ticket");         session.setattribute("default_selected_opd_ticket", "2");          if (session.getattribute("opdticket_blank") != null) {             printpg = session.getattribute("opdticket_blank").tostring();         } else {             printpg = "../opdreport/opdticket_blank.jsp";         }     }      //  printpg = "../opdreport/opdticket_blank.jsp";//this jsp     request.getsession().setattribute("backpage", backpg);     request.getsession().setattribute("printpage", printpg);     request.getsession().setattribute("regno", registration.getregistrationno());     request.getsession().setattribute("pid", registration.getpatientid());      registration = null;     if (request.getparameter("selectedoption") != null) {         string strselectedoption = request.getparameter("selectedoption").tostring();          if (strselectedoption.equals("withoutnk")) {             response.sendredirect("../opdreport/printframe.jsp");             return;         } else if (strselectedoption.equals("withnk")) {             response.sendredirect("../opdregistration/nk1details.jsp");             return;         }      } }

above part of code given. here not able redirect mentioned jsp page.

all datas getting saved without redirecting page giving illegal state exception error. here using 3 radio buttons value 1,2,3 respectively.

the user select radio button according requirement & according redirect respective page.

in probability, you've written response stream before doing sendredirect(). illegalstateexception thrown if try redirect after flushing output stream or writing cookie or header etc.
