Throwing NumberFormat exception for preparedStatement.setObjcet()

Hi,
In our application we are using the Postgres Sql 8.3.3 and jdbc driver is postgresql-8.0-310.jdbc3.

When I am trying to set the value for id(int) like as follows throwing exception.
ps.setObject(1, inputData,columntype);
where inputdate value is 2
if I modified the above statement like as follows then it works fine.
ps.setObject(1, inputData);
I want to know what could be the proble.

Thanks,
Srinvias
