Tool for importing Excel spreadsheets

Question
I need to import some Excel spreadsheets into Java objects. I will use POI to do the task (an old version of it unfortunately). However I wonder if there is some high-level framework to do the same task but declaratively. I'm thinking in Castor and XML. The mapping Excel-Class will be stored in a resource (e.g. an XML file). Yes, I'm a lazy bones. But I don't like having lots of hard-coded POI statements when the user decides to change the input format.
Thanks
Solution
I like JExcelApi very much, it is simple and powerful
OTHER TIPS
There are open source libraries that allow you to treat a spreadsheet like a database and access it via JDBC. Googling for "excel jdbc driver" should help you get started.
There's always the JDBC-ODBC bridge shipped with the JVM
import java.lang.*;
public class jdbcodbc {
public static void main(String[] args) {
// Attempt to load database driver
try
{
// Load Sun's jdbc-odbc driver
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
}
catch (ClassNotFoundException cnfe) // driver not found
{
System.err.println ("Unable to load database driver");
System.err.println ("Details : " + cnfe);
System.exit(0);
}
catch (InstantiationException ex)
{
System.err.println ("Unable to load database driver");
System.err.println ("Details : " + ex);
System.exit(0);
}
}
}
Documentation from Sun website, JDBC-ODBC bridge
Example jdbc url potentially usable from Hibernate, for example:
jdbc:odbc:mydb;UID=me;PWD=secret
