Error "Cannot be resolved to a type" on OwnerPIN, APDU, ISO7816

Question

The error I'm reffering to might clearify the fact that I'm new at Java/javaCard-development.
To learn how it all works I've downloaded an example and try to understand what happens.
I opened the source in Eclipse and get errors "Cannot be resolved to a type" on OwnerPIN, ADPU and ISO7816 classes. I have an Import javacard.framework statement and expected these types to be part of this library.
I guess I'm forgetting something somewhere but couldn't find the soluiton on internet.
import javacard.framework.*; // import all neccessary packages for java card*
import java.applet.;
import java.lang.Object;
public class classpgdata extends Applet {
final static byte PROP_CLASS = (byte) 0x80; // Class of the proprietary APDU commands
static {color:#ff0000}OwnerPIN{color} pin; // the PIN object
public void process({color:#ff0000}APDU{color} apdu) {
byte[] cmd_apdu = apdu.getBuffer();
if (cmd_apdu[{color:#ff0000}ISO7816{color}.OFFSET_CLA] == {color:#ff0000}ISO7816{color}.CLA_ISO7816) {
//----- it is the ISO/IEC 7816 class
switch(cmd_apdu[{color:#ff0000}ISO7816{color}.OFFSET_INS]) { // check the instruction byte
case INS_SELECT: // it is a SELECT FILE instruction
...

Hi,
What you need to do update your Java build path fr the project in your Eclipse project.
Project -> Properties then find Java Build Path.
In the Libraries tab add the {JCDK Home}/lib/javacardframework.jar by clicking the add external JARs button. You may also want to remove the standard Java Runtime (JRE) libraries as you do not build against these.
If you want to use the JC 2.2.1 CAP file converter, you may also want to ensure that the Eclipse compiler is set to compile as Java 1.3 in the Java Compiler section of the project properties.

It also looks like you have added two imports you don't actually want. You only need the javacard.framework.* import.
Cheers,
Shane
