Problem with GenericCatalogDAO JDBC Resultset using parameters not working

Question

Hello
I have a problem with Petstore GenericCatalogDAO. java. The problem is the behaviour of the resultset object when retrieving data from the database.Below are two synareos one that
works (when) hard coded and one that does not work when parameter values passed into the the result set.
1. The code the WORKS.
statement = connection.prepareStatement("select a.productid , name, descn from product a, product_details b
where a.productid = b.productid and locale= 'en_US' and a.catid = 'FISH' order by name"
,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
resultSet = statement.executeQuery();
resultSet.absolute(1);
String s = resultSet.getString(1);
The code that gives me a 'exhausted resultset' error which I think means no results
String[] parameterValues = new String[] { locale.toString(), categoryID };(For example parameters are 'en_US' and 'FISH')
statement = connection.prepareStatement("select a.productid , name, descn from product a, product_details b
where a.productid = b.productid and locale=? and a.catid =? order by name"
,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
for (int i = 0; i < parameterValues.length; i++) {
statement.setString(i + 1, parameterValues[i]);
resultSet = statement.executeQuery();
resultSet.absolute(1);
String s = resultSet.getString(1);
There is obviously a problem using these named parametevalues with these preparedstatement resultset, Does anybody know anything about this and a fix for it????
Cheers. Roger
