Re: next() error

I am using postgresql 8 and the 8 JDBC 3 driver.
I get the next error:
javax.servlet.ServletException: ResultSet not positioned properly,
perhaps you need to call next.
This code used to work on postgresql 7.4.6 and 215 JDBC 3 driver
Has changed something on the server or on the driver?
Thanks for your help.
This is the code on a jsp page:

<%@ include file="Connections/connPubs.jsp" %>

String RecordsetPubs1 = "1";
if (request.getParameter("au_id") != null)
{
RecordsetPubs1 = (String)request.getParameter("au_id");
}
%>
<%
Driver DriverRecordsetPubs1 =
(Driver)Class.forName(connPubs_DRIVER).newInstance();
Connection ConnRecordsetPubs1 =
DriverManager.getConnection(connPubs_STRING,connPubs_USERNAME,connPubs_PASSWORD);
PreparedStatement StatementRecordsetPubs1 =
ConnRecordsetPubs1.prepareStatement("SELECT * FROM public.authors
WHERE au_id = " + RecordsetPubs1 + "");
ResultSet RecordsetPubs1 = StatementRecordsetPubs1.executeQuery();
boolean RecordsetPubs1_isEmpty = ! RecordsetPubs1.next();
boolean RecordsetPubs1_hasData = ! RecordsetPubs1_isEmpty;
Object RecordsetPubs1_data;
int RecordsetPubs1_numRows = 0;
