No class found for inet - Mailing list pgsql-jdbc

Hi all,
    I am using Apache Commons BeanUtils RowSetDynaClass for disconnected
resul tsets. But it gives error when I pass a ResultSet which contains an
inet column type what to do with it. Why postgres is not providing classes
for postgres specific data types ?.
Using Postgres 7.3
