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
