Problems when using absolute() on Oracle JDBC driver

Question

Hi all,
I wrote some codes using JDBC to access a remote Oracle server. After got the resultset, I attempted to use absolute() method to move to a specific row index and got an error. Could anyone please help me to find out the cause and the solution?
Thanks in advanced,
** We have used driver package jdbc/lib/classes.zip in ORACLE 8.1.7
** The total of records in HEFKE000 table > 1000;
** The coding is following:
String url = null;
Connection conn = null;
ResultSet rs = null;
Statement stmt = null;
String query = "select * from HEFKE000";
String dbName = "HE_MI";
String hostName = "NTTD";
String userName = "HOKEN";
String passWord = "manager";
String dbDriver = "oracle.jdbc.driver.OracleDriver";
//Load the Driver
Class.forName(dbDriver);
//get connection
url = "jdbc:oracle:oci8:@NTTD";     
//url = "jdbc:oracle:thin:@" + hostName + ":1521:" + dbName;
conn = DriverManager.getConnection (url, userName, passWord);
// It's faster when you don't commit automatically
conn.setAutoCommit (false);
// Create a Statement object so we can submit
// SQL statements to the driver
stmt = conn.createStatement();
// Submit a query, creating a ResultSet object
rs = stmt.executeQuery(query);
// Get the ResultSetMetaData. This will be used for the column headings
ResultSetMetaData rsmd = rs.getMetaData ();
// Get the number of columns in the result set
int numCols = rsmd.getColumnCount ();
int i;
if (rs.next() == rs.isFirst()) {
rs.absolute(100);
boolean more = rs.next ();
while (more) {
// Loop through each column, getting the
// column data and displaying
for (i=1; i<=numCols; i++) {
if (i > 1) {
System.out.print("|");
if (rs.getString(i) == null)
System.out.print("");
else
     System.out.print(rs.getString(i));
output.println();
// Fetch the next result set row
more = rs.next ();
** The error:
Exception in thread "main" java.sql.SQLException: Invalid operation for forward
only resultset : absolute

Thanks. However, after changed the codes as your suggestion and ran again, I got the following error:
Exception:
java.lang.OutOfMemoryError
<<no stack trace available>>
A note is that, the 'select * from HEFKE000' statement would get around 1,5 millions of records. So, the 'out of memory' above is for client side or for server side?
Thanks,
