Java card SIM toolkit applet - applet

Question

I'm going to develop SIM toolkit applet using eclipse.
I create new java card project and add sim and toolkit packages provided by 3GPP 43.019 specification
And my codes are here.
package com.example.TestPackage;
import javacard.framework.*;
import javacardx.annotations.*;
import static com.example.TestPackage.TestStkAppletStrings.*;
import sim.toolkit.*;
import sim.access.*;
/**
* Applet class
*
* #author <user>
*/
#StringPool(value = {
#StringDef(name = "Package", value = "com.example.TestPackage"),
#StringDef(name = "AppletName", value = "TestStkApplet")},
// Insert your strings here
name = "TestStkAppletStrings")
public class TestStkApplet extends Applet implements ToolkitInterface, ToolkitConstants
{
public static final byte CMD_QUALIFIER = (byte)0x80;
public static final byte MY_INSTRUCTION = (byte)0x46;
private byte[] menuEntry = {(byte)'0',(byte)'3',(byte)'.',(byte)'1',(byte)'9',(byte)' ',(byte)'A',(byte)'p',(byte)'p',(byte)'l',(byte)'e',(byte)'t'};
private byte[] menuTitle= {(byte)'M',(byte)'y',(byte)'M',(byte)'e',(byte)'n' ,(byte)'u'};
private byte[] item1 = {(byte)'I',(byte)'T',(byte)'E',(byte)'M',(byte)'1' };
private byte[] item2 = {(byte)'I',(byte)'T',(byte)'E',(byte)'M',(byte)'2' };
private byte[] item3 = {(byte)'I',(byte)'T',(byte)'E',(byte)'M',(byte)'3' };
private byte[] item4 = {(byte)'I',(byte)'T',(byte)'E',(byte)'M',(byte)'4' };
private Object[] ItemList = { item1, item2, item3, item4 };
private byte[] textDText = {(byte)'H',(byte)'e',(byte)'l',(byte)'l',(byte)'o',(byte)' ',
(byte)'w',(byte)'o',(byte)'r',(byte)'l',(byte)'d',(byte)'2'};
private byte[] baGSMAID = {(byte)0xA0, (byte)0x00, (byte)0x00, (byte)0x00, (byte)0x09, (byte)0x00, (byte)0x01};
private ToolkitRegistry reg;
private SIMView gsmFile;
private byte buffer[] = new byte[10];
private byte itemId;
private byte result;
public TestStkApplet() {
// get the GSM application reference
gsmFile = SIMSystem.getTheSIMView();
// register to the SIM Toolkit Framework
reg = ToolkitRegistry.getEntry();
// Define the applet Menu Entry and register to the EVENT_MENU_SELECTION
itemId = reg.initMenuEntry(menuEntry, (short)0x0000, (short)menuEntry.length,
PRO_CMD_DISPLAY_TEXT, false, (byte) 0x00, (short) 0x0000);
}
public static void install(byte[] bArray, short bOffset, byte bLength) {
TestStkApplet MyStkApplet = new TestStkApplet();
MyStkApplet.register();
}
#Override
public void process(APDU apdu) {
//Insert your code here
if(selectingApplet())
return;
switch(apdu.getBuffer()[1]) {
// specific APDU for this applet to configure the MenuTitle from SelectItem
case (byte)MY_INSTRUCTION:
if(apdu.setIncomingAndReceive() > (short)0) {
Util.arrayCopy(apdu.getBuffer(),(short)0x0005,menuTitle,(short)0x0000,(short)0x0006);
}
break;
default:
ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
}
}
#Override
public void processToolkit(byte event) throws ToolkitException {
EnvelopeHandler envHdlr = EnvelopeHandler.getTheHandler();
ProactiveHandler proHdlr = ProactiveHandler.getTheHandler();
ProactiveResponseHandler rspHdlr ;
boolean repeat;
switch(event) {
case EVENT_MENU_SELECTION:
// Prepare the Select Item proactive command
proHdlr.init(PRO_CMD_SELECT_ITEM,(byte)0x00,DEV_ID_ME);
// Append the Menu Title
proHdlr.appendTLV((byte) (TAG_ALPHA_IDENTIFIER | TAG_SET_CR),
menuTitle,(short)0x0000,(short)menuTitle.length);
// ask the SIM Toolkit Framework to send the proactive command and check the result
if((result = proHdlr.send()) == RES_CMD_PERF) {
rspHdlr = ProactiveResponseHandler.getTheHandler();
switch (rspHdlr.getItemIdentifier()) {
case 1:
// DisplayText High Priority
proHdlr.init(PRO_CMD_DISPLAY_TEXT, CMD_QUALIFIER,DEV_ID_DISPLAY);
proHdlr.appendTLV((byte)(TAG_TEXT_STRING| TAG_SET_CR), DCS_8_BIT_DATA,
textDText,(short)0x0000, (short)textDText.length);
proHdlr.send();
break;
}
}
break;
}
}
}
As I run it and start simulator, it returns error in creating and selecting applet.
The errors in eclipse here.

I don't know how I fix it.
In addition, I want to ask more questions.
Simulator does not support SIM toolkit ?
What is the INS b8 means? is there any specification I can refer?
I don't know exactly how I import sim.toolkit.* and sim.access.*. please explain it in details.
Could someone explain to me?
Please let me know about it.
