Re: error when using move, any suggestions?

Barry,
Thanks for the tip, however the error is still there.
Here's the code:
import blastDb.*;
import java.sql.*;
import java.io.*;
import java.util.*;
import java.lang.*;

public class TestFetchSize
{
    public static void main(String[] args)
    {
        try
        {
            BlastDB db = new BlastDB();

            Statement stmt = db.connection.createStatement();
            int counte = 0;
            //stmt.execute("begin work");
            db.connection.setAutoCommit(false);
            stmt.execute("declare test cursor for select id from region
where protein_database = 1");
            ResultSet rs;
            System.out.println("here1");
            stmt.execute("move forward 99 in test");
            System.out.println("here2");
            while(stmt.execute("fetch forward 2 in test"))
            {
                rs = stmt.getResultSet();
                if (rs.next())
                {
                    ++counte;
                    while (rs.next())
                    {
                        ++counte;
                    }
                }
                else
                    break;

            }

            rs = stmt.getResultSet();
            if (rs.next())
                System.out.println("ok");
            else
                System.out.println("NO");
            System.out.println(counte);
            db.connection.commit();
            //stmt.execute("end work");
        }
        catch (Exception e)
        {
            e.printStackTrace();
            System.out.println(e.getMessage());
        }
    }
}

This is the output:
