jdbc driver problem? - Mailing list pgsql-jdbc

Hi all,
   Iam using postgresql-8.2dev-501.jdbc3.jar jdbc.
   We used a query like
            SELECT * FROM patient_head WHERE  patient_name = ?
   in the prepared statement. And set the parameter as setString(1,name) , where 'name' is the java string variable.
   while printing the prepared statement the query is displayed like
            SELECT * FROM patient_head WHERE  patient_name = James Cameroon
   instead of
             SELECT * FROM patient_head WHERE  patient_name = 'James Cameroon'
   with single quotes.
   It happens in both the 7.4.7 and 8.1 version of the postgresql.
   Because of this the query does not executes and no result is fetched.
   Why? do i miss anything? please help?

with advanced thanks
