"Invalid op for forward-only resultset : last"

Question

I am trying to use the oracle jdbc drivers in classes12.zip to connect to an Oracle 8.0.6 database. The documentation for classes12.zip says that these drivers allow scrollable ResultSets, but whenever I try to use ResultSet.absolute(), ResultSet.relative(), ResultSet.first(), or ResultSet.last(), I get SQLException : "Invalid op for forward-only resultset : last"
Is there something special I need to do to my statement or resultset object to enable a scrollable ResultSet? My code looks like this:
Class.forName("oracle.jdbc.driver.OracleDriver");
String userID = "scott";
String passwd = "tiger";
//I'm certain I have the correct
//connection data in the
//real version of this program
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@XXX:XXX", userID, passwd);
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select * from mytable");
Any suggestions?

What if I was using a CallableStatement (prepareCall() & execute()) to get my result set as a return value from a PL/SQL procedure instead of above case where a Statement (createStatement() & executeQuery()) were used. How can I make the ResulSet be scrollable? Please see below sample code.
CallableStatement cstmt = dbConn.conn.prepareCall("{ ? = call pkg_MyPkg.fn_MyFn }", ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
boolean b = cstmt.execute();
OracleCallableStatement tstmt = OracleCallableStatement)cstmt;
ResultSet cursor = tstmt.getCursor (1);
// this works AOK
while (cursor.next ())
System.out.println(cursor.getString(1));
// the following does not work
b = rsetGetFn.first();
System.out.println(cursor.getString(1));
b = rsetGetFn.last();
System.out.println(cursor.getString(1));
The call cursor.getType() returns ResultSet.TYPE_FORWARD_ONLY, how can I get it to be ResultSet.TYPE_SCROLL_INSENSITIVE or ResultSet.TYPE_SCROLL_SENSITIVE?
Any help will be apreciated.
