Cordova.exec function doesn't run the native function - plugins

Question

I try to make a cordova plugin in IBM worklight.
Javascript:
HelloWorld = {
sayHello: function (success, fail, resultType) {
Cordova.exec(
success,
fail,
"HelloWorld",
"HelloWorld",
[resultType]
);
}
};
function callFunction() {
HelloWorld.sayHello(basarili, basarisiz, "sinan");
}
Java:
package com.Cordova1;
import org.apache.cordova.api.CordovaPlugin;
import org.json.JSONArray;
import android.util.Log;
public class HelloWorld extends CordovaPlugin {
public boolean execute(String arg0, JSONArray arg1, String arg2) {
Log.d("HelloPlugin", "Hello, this is a native function called from PhoneGap/Cordova!");
return true;
}
}
When I call callFunction I see that fail function worked. Also, I can't see any HelloPlugin message in log window.
What can I do ?

Answer 1

module 09_3 ApacheCordovaPlugin in the samples is indeed using the deprecated Plugin class instead of CordovaPlugin. I have rewritten the HelloWorldPlugin class in module 09_3 to eliminate the deprecated Cordova Plugin API usage. The sample is working fine.
package com.AndroidApacheCordovaPlugin;
import org.apache.cordova.api.CallbackContext;
import org.apache.cordova.api.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;
public class HelloWorldPlugin extends CordovaPlugin {
#Override
public boolean execute(String action, JSONArray arguments,
CallbackContext callbackContext) throws JSONException {
if (action.equals("sayHello")) {
String responseText = "Hello world";
try {
responseText += ", " + arguments.getString(0);
callbackContext.success(responseText);
return true;
} catch (JSONException e) {
callbackContext.error(e.getMessage());
}
} else {
callbackContext.error("Invalid action: " + action);
return false;
}
return false;
}
}

A couple of things, 1) did you add a line for your plugin into the config.xml file? and 2) you seem to be overriding the wrong method in CordovaPlugin. It should be:
public boolean execute(String action, JSONArray args, CallbackContext callbackContext)

Answer 3

I was having the same problem. Have a look at module 09_3 ApacheCordovaPlugin in the samples. That example does work for me, but they are using the deprecated Plugin class instead of CordovaPlugin.
import org.apache.cordova.api.Plugin;
import org.apache.cordova.api.PluginResult;
...
public class HelloWorldPlugin extends Plugin {
public PluginResult execute(String action, JSONArray arguments, String callbackId) {
The deprecated class returns PluginResult, not a boolean. I've tried the same code using the CordovaPlugin signature and that results in a fail every time. Apparently whatever WL code is invoking the plugin is apparently expecting the signature of the deprecated class.

I solved the problem.
I use the version 2.4 of cordova. I can't understand why it didn't work. when I use "cordova.exec" it doesn't work, however when I use PhoneGap.exec it works.
Also I looked for the definition;
In the last line of cordova-2.4.0.js, it says
var PhoneGap = cordova;
Ok, Phonegap was defined, but I don't know why cordova doesn't work.
Thank you for your answers.
