JS Helper Libraries throwing ClassNotFoundException

[autossincool (Ralf)]

My openhab test instance (Openhab 3 M5) is running on MacOS.

I downloaded the helper libraries from here and followed this installation guide.

After copying the HelloWorld.js into the proper directory (Step 9) and starting Openhab, I can see the following entry in the openhab.log

2020-12-17 08:34:22.975 [INFO ] [ab.core.service.AbstractWatchService] - Loading script '/Applications/openhab-3.0.0.M5/conf/automation/jsr223/javascript/personal/HelloWorld.js'
2020-12-17 08:34:24.648 [ERROR] [ipt.internal.ScriptEngineManagerImpl] - Error during evaluation of script 'file:/Applications/openhab-3.0.0.M5/conf/automation/jsr223/javascript/personal/HelloWorld.js': java.lang.ClassNotFoundException: org.eclipse.smarthome.model.script.actions.ScriptExecution cannot be found by org.openhab.core.automation.module.script_3.0.0.M5

To run another test, I created a new rule in the MainUI with the code below:

var OPENHAB_CONF = Java.type('java.lang.System').getenv('OPENHAB_CONF');
load(OPENHAB_CONF + '/automation/lib/javascript/core/actions.js');

LogAction.logInfo("Rules", "test");

This is what is written into the log:

Still working on them… shouldn’t be long…

[Solved] OH3: How to get running with JSR223 JavaScript Rules?

You are using an unstable non-production release of OH… how is it over there on the bleeding edge!? While you’re over there, you might as well go ahead and get everything prepared for the helper libraries and I’ll join you when things stabilize! I have been busy with other projects and finalizing some add-ons for use with OH 2.5.x. When they are done, I will be creating OH3 versions of the add-ons and making sure the helper libraries are usable. I’m already aware of several things that …

[autossincool (Ralf)]

Thank you

[volfan6415 (Zachary Christiansen)]

Any updates to this now that OpenHAB3 is out? Need any help? Is there a branch on the github repository for a version to test out?

[Ben_P]

If you read through the migration stuff, then you noticed that eclipse smarthome is no longer relevant.
So what I did is go through all the automation/lib/javascript/core scripts and updated all references to org.eclipse.smarthome (most of them with org.openhab) and replaced joda time with ZonedTime.

Now, that is really,really quick and dirty, but it does seem to work and the HelloWorld.js executes (after putting in Karaf log:set DEBUG jsr223 even for info level logging).
I attached the scripts from the automation/lib/javascript/core folder. Note that this is by no means guaranteed to work, and is absolutely not recommended, but it does seem to work for simple stuff
Renamed with extension .txt to allow to upload.
Hope this gets someone started…

actions.js.txt (1.6 KB) conditions.js.txt (1.4 KB) metadata.js.txt (9.3 KB) PersistenceExtensions.js.txt (6.6 KB) rules.js.txt (6.7 KB) triggers.js.txt (8.0 KB) utils.js.txt (20.8 KB)

[Ben_P]

After I updated the js files, it took me a while to figure out how to get Telegram working, since the definition in the documentation does not work anymore.
I found that, using the updated files from my post above (Note that Log was wrongfully updated and does not work still), I was able to create a rule that works
I think this is the correct syntax for all the getActions(“xx”,“yyy”) in the current documentation that no longer work ?
In short : include actions.js and call Things.getActions(“xx”,“yyy”)

// my Telegram Thing is defined as : 
//Thing telegram:telegramBot:TelegramBot [ chatIds="XXX",  botToken="XXX" ]

'use strict';
var OPENHAB_CONF = Java.type("java.lang.System").getenv("OPENHAB_CONF"); 
load(OPENHAB_CONF+'/automation/lib/javascript/core/rules.js');
load(OPENHAB_CONF+'/automation/lib/javascript/core/actions.js');
var me = "button-rules.js";

//### Action on button pressed
JSRule({
	name: "Button pressed",
	description: "Pressing the button triggers Telegram message",
	triggers: [ 
		UpdatedEventTrigger("Button_1")
	],
	execute: function( module, input){
        logInfo("Button pressed !"); 
        //Use your Telegram Thing definition as second parameter
		var telegramAction = Things.getActions("telegram","telegram:telegramBot:TelegramBot");
        //Use actions as defined in the documentation, parameters chatId and message
        //Note that the chatId is a regular number, so not with the L suffix, that will give an error !
        //So define like :  telegramAction.sendTelegram(123456, "Test"); 
        //AND NOT LIKE:  telegramAction.sendTelegram(123456L, "Test"); 
		telegramAction.sendTelegram(XXXXXXX, "Test");  
	} 
});

Did you ever get your JS Helper libraries to load? I am having a very similar problem with OH3.0.1. My gripe is at OH3 How to load Javascript rules.js . Thanks!
