Passing ResultSet from one function to another

Question

Hi friends,
Greetings.
I am a beginner in Java.
I am doing an exercise using jdbc:odbc driver where i have to query the database in one function and pass the ResultSet to another function.
Let function1 be
ResultSet select(String sel) // sel is the id of what is to be selected { Resultset rs= //coding return rs; }
Let function2 be
function2 { String id="abc"; ResultSet rs1=select(id); //code to print rs1 }
Is my code correct? i get a NullPointerException always.
Please help
Regards.

Well,
how do i pass the query Results?
Actually i have a database in the server and i am the client.
Client sends the id to the server. Server processes. finds the id and returns the name and other details using SQL statement:
select * from table1 where id="abc";Server should return these details back to the client.
IF no such id exists then server should send the client the following result:
//print that the given id does not exist and these are the ids and names in table1
select * from table1;How can i do it using jdbc odbc driver?
Thank you in anticipation to your reply!
Regardssee my reply to your other post.
write a server side component that opens the connection to the database, loads the ResultSet into a data structure, closes the ResultSet, and returns the data structure to the client.
the client should not be dealing directly with the database.
