java - NoSuchMethodError: model.AddEvents.getStartDate()Ljava/lang/String; -

i don't know what's happening here. used date data type save data in database , it's keep giving error-error accessing database:javax.servlet.servletexception: java.lang.nosuchmethoderror: model.addevents.getstartdate()ljava/lang/string;.i'm sure servlet part has error. think problem in usage of date type in servlet , java bean because used string , worked perfectly.pls guys :)

you should parse date instead of system.out.println(myevent.getstartdate());

date date = myevent.getstartdate() simpledateformat sdf = new simpledateformat("yyyy-mm-dd hh:mm:ss");    system.out.println(sdf.format(date));
