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:
