cordova.exec错误找不到类

Question

I'm attempting to write a plugin for phonegap that will access native Java that I have written. The only problem is that when I call cordova.exec, the failure callback message is "Class not found". I'm assuming this means that it can't find the java file, but I don't know why.

Here is my code. Javascript:

var SerialHelper = {
        getName: function(){
            return "this is the name"
        },
    getSerial: function(success, failure) {
         cordova.exec(
           success, // success callback function
           failure, // error callback function
           'com.isabellaproducts.serialhelper.SerialHelper',
           'getFableSerial',
           []
        );
    }
}
module.exports = SerialHelper;

Java:

package com.isabellaproducs.serialhelper;

import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONObject;
import org.json.JSONArray;
import org.json.JSONException;
import org.apache.cordova.*;


public class SerialHelper extends CordovaPlugin
{

    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {

        if ("getFableSerial".equals(action)) {
            String serial = "15345344132354";
            callbackContext.success(serial);
            //callbackContext.sendPluginResult(new PluginResult(Status.OK, serial));
            return true;
        }
        else{
            callbackContext.error("method not found");
            return false;
        }
    }
}

plugin.xml

<?xml version="1.0" encoding="UTF-8"?>

<plugin xmlns="http://www.phonegap.com/ns/plugins/1.0"

        <config-file target="res/xml/config.xml" parent="/*">
            <feature name="SerialHelper">
                <param name="android-package" value="com.isabellaproducts.serialhelper.SerialHelper"/>
            </feature>
        </config-file>

     </platform>          
</plugin>

In logcat, I get this error:

D/PluginManager(12316): exec() call to unknown plugin: SerialHelper

Any help would be much appreciated.

Thanks.

Wow....so, I was putting the plugin in a custom package. That was messing everything up!

The simple change from: com.isabellaproducts.serialhelper to com.phonegap.plugins.serialhlper

It now looks like this. Javascript:

var SerialHelper = {
        getName: function(){
            return "this is the name"
        },
    getSerial: function(success, failure) {
         cordova.exec(
           success, // success callback function
           failure, // error callback function
           'SerialHelper',
           'getFableSerial',
           []
        );
    }
}
module.exports = SerialHelper;

Java:

package com.phonegap.plugins.serialhelper;

import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONObject;
import org.json.JSONArray;
import org.json.JSONException;
import org.apache.cordova.*;


public class SerialHelper extends CordovaPlugin
{

    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {

        if ("getFableSerial".equals(action)) {
            String serial = "15345344132354";
            callbackContext.success(serial);
            //callbackContext.sendPluginResult(new PluginResult(Status.OK, serial));
            return true;
        }
        else{
            callbackContext.error("method not found");
            return false;
        }
    }
}
