Hi, rowset implementation is giving a problem

The cachedrowsets created as

are giving a problem.The error displayed is
"Invalid scale size. Cannot be less than zero"
What might be the reason for the error.

import com.sun.rowset.*;
public class FilteredRowSetEx {
     public static void main(String args[])throws Exception{
          String uname = "vsg";
          String pwd = "vsg";
          String url      = "jdbc:oracle:thin:@localhost:1521";
          String driver = "oracle.jdbc.driver.OracleDriver";
          String query = "select clusterid from tab";
          Connection con = null;
          try{
               Class.forName(driver);
               System.out.println("driver loaded");
               con = DriverManager.getConnection(url,uname,pwd);
               System.out.println("Connection created : " + con);
               FilteredRowSet frs = new FilteredRowSetImpl();
               System.out.println("frs creatd");
               frs.setFilter(null);
               frs.setCommand(query);
               frs.execute(con);
               while(frs.next()){
                    System.out.println("Cluster-ID : " + frs.getString(1));
          catch(Exception ex){
               System.out.println("Exception in : " + ex.getClass().getName() + " and is: " + ex.getMessage());
          finally{
               con.close();
The query is giving problem when we try to select a numeric field as the default scale is 0.
Is there any method to set the scale or any other way to retrieve the numeric fields.
Please help me.
