Java Database Connectivity (JDBC)

Hey All,

I am inserting date from frontend to SQL DB with servlet where I havee put below function in try {} of Servlet :

java.sql.Date date_fe = null;
java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("dd/MM/yyyy");
date_fe = new java.sql.Date(formatter.parse(empl_doj_fe).getTime());

Sometimes it is taking values such as 01/01/2001 but very next moment it is giving problem for same date format, the exception it returns is :

java.sql.SQLException: ORA-00001: unique constraint (NAMAN_LSR.SYS_C0014552) violated

I couldn`t get the error in this, so any help will be welcomed.

Thax & rgds,
