Error with a hibernate query - Mailing list pgsql-jdbc

The Java code:

public class User {

    private Long id;
    private String username;
    private String password;

        //...
}

The DB table:

create table USERS (
    id             SERIAL UNIQUE primary key,
    username     VARCHAR(80) NOT NULL,
    password    VARCHAR(80) NOT NULL,
        ...
);

The Hibernate query:

getHibernateTemplate().findByNamedParam("select u from
                      User as u where u.username=:username and
u.password=:password", new String[] { "username",
"password" }

From the stack, the following error seems to be on the
JDBC driver side. Any suggestions of solving this
problem?


org.springframework.jdbc.BadSqlGrammarException: Bad
SQL grammar [] in task 'Hibernate operation'; nested
exception is java.sql.SQLException: ERROR: operator
does not exist: character varying = bytea
