I think that's normal. I don't recall the JDBC spec saying that you 
have a chance the server will remember that you created a 
PreparedStatement for the same query text before. You have to cache the 
PreparedStatement object in your app, not the query string.

BTW that's the same for perl/DBI. At least for Oracle.
