    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1074)

 CREATE... PROCEDURE `Add(Id int,
 Date_In varchar(50),Out result int)
 BEGIN
 IF (select count(*) from myTable Where DATE_FORMAT(Datein,     '%d/%m/%Y')=DATE_FORMAT(Date_In, '%d/%m/%Y') and id=Id) < 1 then
BEGIN
INSERT INTO myTable (id, DateIn) 
VALUES (id,str_to_date(Date_In,'%d/%M/%Y %H:%i'));
set result=1;
END;
END if;
end

java code:
String date = request.getParameter("date");
String time = request.getParameter("time");
String dateTIme = date + " " + time + ":00";

and insert statement goes here.
