However, I get an error as below.
org.postgresql.util.PSQLException: No value specified for parameter 1.

I'm not being able to figure out why this is happening . However, when I try
to run the query printed by the toString() method at the database, it works
perfectly . Am I missing something in the syntax?
Thank you for your time.

The bean.getWenexa_id() call returns null?
> stmt.setString(2, bean.getRr_number());
> stmt.setString(3, bean.getConsumer_name());
> stmt.setString(4, bean.getResiding_village());
> stmt.setString(5, bean.getContact_no());
> stmt.setString(6, bean.getContact_person());
> if (bean.getRep_date() == null || bean.getRep_date() == "") {
> bean.setRep_date(null);

The check and set of null here is redundant, and you are comparing the
identity of the rep_date string with the empty string. Unless the
rep_date string is interned this will most likely not work as you
expect. The clause should be:
if ("".equals(bean.getRep_date())) {
bean.setRep_date(null);
}
Although I have to wonder why are you representing a date in your bean
as a String rather than a Date. If it was a Date, then the previous
clause would be unnecessary and the next clause could be:
if (bean.getRep_date() != null) {
stmt.setDate(7, new java.sql.Date(bean.getRep_date().getTime()));
} else {
stmt.setNull(7, Types.DATE);
}
That would save you the cost of parsing a date from a string.

The toString() call is redundant, an implicit conversion will occur
without it.
