IN JAVA CODE IN JSP as below i m getting null value for field"noOfRecords".
if (request.getMethod().equalsIgnoreCase("POST")) {
try
{
noOfRecords=Integer.parseInt(request.getParameter("noOfRecords").trim());
}
catch(NumberFormatException e)
{
throw new Exception("No of records Field should be numeric.");
}
catch(NullPointerException e)
{
throw new Exception("No of records should be specified.");
}
HTML 코드는 아래와 같습니다. 만약 다중 부호화 ('다중/폼 데이터')를 이용하여 작성하기 때문에자바 코드에서 폼을 제출할 때 request.getParameter()에서 null이 발생합니까?
