Help: Loading custom JCShell plugin

Question

Hi, when I try to register a custom JCShell plugin. I get the following error:
cm>  /applet
Nickname   AID                              Plugin
cm         A000000003000000                 com.ibm.jc.tools.CardManagerPlugin
eclipse    00000000                         com.ibm.bluez.jcop.eclipse.internal.ui.views.shell.EclipseShellPlugin
cm>  /register dosf A000010203 com.ibm.jc.tools.DosfShell
jcshell: Failed to load plugin <com.ibm.jc.tools.DosfShell>: java.lang.ClassNotFoundException: com.ibm.jc.tools.DosfShellI believe it's not finding the jar file I created with the plugin. I have tried putting in a number of directories, including in the D:\eclipse\plugins\com.ibm.bluez.jcop.eclipse_3.1.2\lib where the offcard.jar is placed.
Help, I am not sure what to try next. Could it be how I created the jar file?
The documentation does not walk through the entire process (i.e. where to place the jar). I've tried their example and same problem.
Here is a snip of the code:
package com.ibm.jc.tools;
import  com.ibm.jc.*;
//import  com.ibm.jc.tools.JCShellPlugin; got warnings on this not sure why?
public class DosfShell extends com.ibm.jc.tools.JCShellPlugin {
     // commands of the plugin
     private static String[] cmdNames = {
          "sampleCommand",
I am using JCOP 3.1.2 and Eclipse 3.2.1
Thank you for any help.

Hi Maguar,
providing a custom JCShell plugin has been supported by the JCOP-Tools with an own extension point "shellplugins". This extension point is responsible for the integration of individual JCShell plug-in.
The JCShell (JCOP Offcard API) supports registering and activation of individual plug-ins. Such a plug-in, delivered by any provider, must extend the �com.ibm.jc.tools.JCShellPlugin� class.
The custom JCShell-plugin class must be declared in a simple Eclipse plug-in. This plug-in contains only a source folder with this Java class (there are no requirements for the package name).
Add the JCOP-Tools Eclipse plug-in to the required plug-ins in the manifest of your plug-in.
Add an extension for the extension point "com.ibm.bluez.jcop.eclipse.shellplugins" to the manifest of your plug-in. The entry in the plugin.xml should look like this:
<plugin>
   <extension
         point="com.ibm.bluez.jcop.eclipse.shellplugins">
         <shellplugin
              class="com.ibm.jcop.test.MyShellPlugin"/>
   </extension>
</plugin>It is important that the extension point declares exactly the class file for the extended JCShell plug-in.
Configure the plug-in build so, that the class file is part of an internal JAR file.
Start your Eclipse IDE and install this new Eclipse plug-in . Register your applet in the JCShell, select your applet and display the help. Now you will find the command �sample-cmd� in your command list.
