moving throw the resultset

hi,

    i am making a servlet to move to any row from the resultset.
    i have driver jdbc6.4 and java1.2.
    i have done a
        resultset rs = stmt.executeQuery("select * from data");
        rs.absolute(2) --->  to move to second row
    but does not work .. in the logs said:
        java.lang.AbstractMethodError: postgresql/ResultSet.absolute
        at myservlet.doGet(Compiled Code)
        at myservlet.doPost(listparte.java:35)
        at org.apache.jserv.JServConnection.processRequest(Compiled
Code)
        at org.apache.jserv.JServConnection.run(Compiled Code)
        at java.lang.Thread.run(Compiled Code)

    how can i do that?
    any suggestions will be pleased,

thanks in advance,

marcos
