Handling Date
Scenario:
I have news archive html form that'll search news from this date to this date.
I have given option list as day, month, year
I am getting value of month as number and started from 0 (i.e. jan)
2. in servlet file I am getting the parameters of day, month, year
and combining them with a String startDate=day+"-"+month+"-"+year;
but facing problems

the message appears "Not a valid month"
why becuase I am getting month as one digit e.g. 2 for March
but when am making query it gives error as the oracle oracle format is to_char(news_date,'dd-mm-yy');
when am changing the format as to_char(news_date,'dd-m-yy'); it gives the error "date format not recognized"
Question:
Can i change the calendar date 01 despite 1?
or anyother solution please
thanks for your help

Use SimpleDateFormat to convert between String and Date.
Date date = new Date(); // Today's date.
SimpleDateFormat sdf = new SimpleDateFormat("dd-M-yy");
String dateString = sdf.format(date); // 01-5-07
And the reversed way:String dateString = "01-5-07";
SimpleDateFormat sdf = new SimpleDateFormat("dd-M-yy");
Date date = sdf.parse(dateString); // Tue May 01 00:00:00 [zone] 2007
You can find the date format patterns in the SimpleDateFormat API. Kindly click at the links I provided here above and read them. You learns a lot from the API documentation.

" a.news_id=b.news_id and product='"+product+"' "+
"and news_date>='"+oraStart+"' and news_date<='"+oraEnd+"'");
while(rs.next()){
news_id=rs.getInt(1);
