How to run a library in Java Card

Question

Hi guys
I have a question related to the running in emulator. Well, I now have 2 separated projects, one is class library and the other is java card applet. Both of them are constructed by Netbeans
When I build the classic library, it is fine. I have class file, cap file and export file of this package. This is the source code of my class library
package lib4;
public class lib4 {
    public short func1(){
        return (short)0x1234;
}And then, I use this library for the java card applet which is developed onto another project in Netbeans as well. This applet invokes func1 in class lib4. This is the source code of the applet
package app1;
import javacard.framework.*;
import lib4.*;
public class app1 extends Applet {
    public static void install(byte[] bArray, short bOffset, byte bLength) {
        new app1();
    protected app1() {
        register();
    public void process(APDU apdu) {
        //Insert your code here
        short t;
        lib4 d= new lib4();
        t = d.func1();
        ISOException.throwIt((short)t);
}However, when I build this applet by Netbeans, the error is "error: export file lib4.exp of package lib4 not found.". I think that's fine if I build them by ANT TASK. Nervertheless, for the sake of emulating, I want to build them onto Netbeans.
This is the whole result of the build

First things first.
Do you know how to compile a simple hello word program, get it to compile, and run it in jbuilder? Do you know how to do other basic programming tasks (ignoring iADF for now) in the IDE? If not, you need to concentrate on how to use jbuilder before messing with Oracle ADF (Oracle Application Development Framework). Alternately, if you are very familiar with another IDE such as Eclipse, you can look at ADF plugins for it instead (if they exist). If you are not familiar with Java, its supporing technologies, and an IDE very well, I suggest you drop ADF and work on simpler architectures because ADF is way, way too advanced for you at this time. Instead, spend your time reading books on Java, etc from cover to cover and working through a number of their examples instead.
Assuming you are an experienced programmer and plan to go ahead with ADF, I suggest you go to amazon.com and order a book on ADF that has good reviews. Read it from cover to cover and work through a number of the book's examples. You should start out with a very very simple ADF project before attempting something more complicated, then build on it. If you are not familiar with some of the components of ADF such as JSF, I suggest you create a few simple projects using them in isolation before combining them all under ADF.
