PostgreSQL JDBC drive does not fully support JDK1.3

I am using PostgreSQL JDBC drive jdbc7.0-1.2.jar on Redhat Linux 6.5
with PostgreSQL 7.0.3-2

When I

ResultSet result = statement.executeQuery(sqlStatement);

int fromRow = 10;
int toRow = 20;
// my SQL statement returns few thousand rows to ResultSet
// I only want to display result.next() fromRow to toRow

result.absolute(fromRow)
int rowNumber = result.getRow();
out.println("Current row = " + rowNumber);
// Here is the problem, the result.absolute(int i) never go the row
number i
// It always stay in row 0 !!

while(result.next()) {
rowNumber = result.getRow();
if (rowNumber > toRow)
break;
// else display rows
// ......
}
