Unable to connect offcard terminal with jcop simulator

Question

Hi all,
I have made a JavaCard applet, called DisplayApplet.
I am using Eclipse with the JCOP tools plugin.
But now I want to make use of an own Terminal that connects to the applet and communicates to it using APDUs.
I don't have a smart card reader/card, so I want to use the simulation environment.
Now I read that I must use the "Remote" value in the JCTerminal constructor to connect to the simulation environment, but it doesn't work (of course I specify the remote value as input parameter).
I am unable to open a terminal.
I get the following exception at the term.open() command:
can't find/open/connect/reset smartcard/reader:
Failed to open [localhost:8050]: Connection refused: connect
Can anyone tell me what's wrong and how I can connect from an own made terminal to a JCOP simulation (I want to run the terminal within Eclipse, because I want to add a UI later on top of it) ??
Here is the code of my own made HostTerminal:
import com.ibm.jc.*;
public class HostTerminal {
     public static final String remoteTermName = "Remote";
     public static final String nativeTermName = "pcsc:4";
     public static final String remoteTermPara = null;
     public static final String nativeTermPara = null;
     public static void main(String[] args) {
          String termName = nativeTermName;
          String termPara = nativeTermPara;
          if (args.length > 0) {
                               if (!args[0].equals("native")) {
                    if (args[0].equals("remote")) {
                         termName = remoteTermName;
                         termPara = remoteTermPara;
                    } else {
                         try {
                              System.out.println("args[0] > " + args[0]);
                              System.out.println("args[1] > " + args[1]);
                              termName = args[0];
                              termPara = args[1];
                         } catch (Exception e) {
                              System.out.println("invalid command line options");
                              System.exit(1);
          // create terminal, i.e. create a connection to a reader
          // and wait for a card insertion
          JCTerminal term = null;
          try {
               term = JCTerminal.getInstance("Remote", null);
               term.open();
               term.waitForCard(5000);
          } catch (Exception e) {
               System.out.println(
                    "can't find/open/connect/reset smartcard/reader: "
                         + e.getMessage());
               System.exit(1);
          System.out.println("Connected to reader and card terminal ...");
          // now get the object representing the connection to the card
          JCard card = null;
          try {
               card = new JCard(term, null, 1000);
          } catch (Exception e) {
               System.out.println(
                    "can't connect to card in reader: " + e.getMessage());
               System.exit(1);
          String s;
          // get atr of card and print it
          try {
               ATR atr = card.getATR();
               s = JCInfo.atrToString(atr);
               System.out.println("Connected to card and received ATR: " + s);
          } catch (Exception e) {
               System.out.println("can't get ATR: " + e.getMessage());
               System.exit(1);
          // Note here that the DisplayApplet has to have to aid "display". The IDE
          // supports ascii characters in AIDs by using | when editing AIDs.
          // For instance, |display results in 636F756E746572.
          System.out.println("Selecting Display applet ...");
          DisplayApplet displayApplet = null;
          try {
               byte[] aid = ("phil0Display").getBytes();
               displayApplet = new DisplayApplet(card, aid);
               displayApplet.select();
               s = JCInfo.toHex(aid, 0, aid.length);
               System.out.println(
                    "Selecting of Display applet with aid " + s + " succeeded");
          } catch (Exception e) {
               System.out.println("can't select Display: " + e.getMessage());
               System.exit(1);
          }

If you run the JavaCard simulator from within Eclipse make sure you disconnect the JCOP shell before trying to connect via JCTerminal() from your Java program. Use the command /close
If you want to disconnect the JCOP shell automatically modify your "Java Card Application" run-configuration:
set Shell commands to execute: to /close
BTW: You were talking about JCOP 3.0, the Eclipse 2.1-plugin or do you use the new pre-release version JCOP 3.1 for Eclipse 3?
