I have a date field in my JSP, I get it as a string in my controller through get parameter method. But from there I have no clue how do I convert it into date format and insert into database. Also I found in datebase that the date format is yyyy-mm-dd hh:mm:ss something like that. I assume there are ways of doing it and some standard way of doing it. Please suggest me on this.
One of the nice things about JDBC is, as a developer, you don't to worry about date format. For adding a date to the database create a valid java.sql.Date (similar to java.util.Date) object and using a PreparedStatement, such as ps, call ps.setDate(numericIndex,dateValue). The JDBC driver will handle the conversion of the date format once you move it to a valid Java object.
And as always I have to say... PLEASE DO NOT PUT JDBC CODE INSIDE A JSP!!! Move your JDBC code to a reusable utility class. JDBC code inside a JSP is inherently unsafe and not reusable.
