Error in importing user-created jar file & cannot find symbol

Question

Hello.
I try to import the jar file made from common classes in the previous project. by using NB 5.5.1.
The jar file is named as 'tpslib.jar'
The previoud package name is 'tps'.
I added tpslib.jar in the library, and removed the class files from the orginal project, because the class files exist in the tpslib.jar.
THe jar file has 8 class files inclduing the following class, ReservationData.
My question is why the follwoing fuction call try to the method in the previous package, tps instead of those of tpslib.jar.
If you have anyone to answer me, it will be very appreciated.
Tae
package tps;
import java.sql.*;
import java.util.*;
import java.io.*;
import tpslib.*;
public class tpsPWSImpl implements tpsPWSSEI {
public ReservationData reserve(ReservationData request) throws java.rmi.RemoteException {
request.print();
requestLocal.print();
if (!request.equalsCoreOf(requestLocal)){
cFlag = true;
System.out.println("reserve: WARNING ");

Does your jar include:
/a/Main.classWith class Main defined in package, er, "a"?
