Javascript JSR223 with Next-Gen Rules Add-on not working

[mdk (Markus Klieber)]

Hi Community,

I`ve got a problem to get the Next-Gen Rules working with Javascript.

I did the following steps:

• Installed openHAB 2.4.0.M7 via docker on Ubuntu 18.04.1 LTS
• Installed Rule Engine (Experimental)
• Installed openHAB 2.x: JSR223 JavaScript Code since 2.4
• Created new rule with action execute a given script and the following script:

load(Java.type("java.lang.System").getenv("OPENHAB_CONF")+'/automation/jsr223/jslib/JSRule.js');
logInfo("Hello World!");

When I execute the rule manually, I get the following error:

2018-12-13 17:57:27.128 [WARN ] [omation.core.internal.RuleEngineImpl] - Fail to execute action: 2

What do I miss? Do I have to install something?

[5iver (Scott Rushworth)]

@mdk

Installed openHAB 2.x: JSR223 JavaScript Code since 2.4

What is this? Have you tried the example script from here, just to get back to the basics? There is nothing else that you would need to install, but I’m not sure what libraries you are using.

[mdk (Markus Klieber)]

Please have a look https://github.com/lewie/openhab2-javascript and https://community.openhab.org/t/experimental-next-gen-rules-engine-documentation-4-of-writing-scripts/55963

I want to execute an action and therefor need getAction Method from lewie’s library. Can I execute an action with the basics?

[5iver (Scott Rushworth)]

Oh OK… I understand better what you are trying to do… use @lewie’s libraries in a Paper UI rule’s Action. @rlkoshak may be able to help with that!

[rlkoshak (Rich Koshak)]

@mdk

Can I execute an action with the basics?

Yes. See Experimental Next-Gen Rules Engine Documentation 4 of : Writing Scripts.

Note that is the fourth in a series of currently five postings on the PaperUI Rules. You might find useful info on the other four as well. See the navigation links at the bottom of each posting to navigate between them. There is still a lot to document but there is enough to get you started.

@mdk

When I execute the rule manually, I get the following error

Be carful. Unless the bug was fixed, if you trigger the rule manually the first time after saving it it will break the rule and you will have to delete it and recreate it. The first time a timer triggers must be from an event

[5iver (Scott Rushworth)]

@rlkoshak

manually the first time after saving it it will break the rule and you will have to delete it and recreate it.

When I was testing this, just resaving the rule was sufficient.

[mdk (Markus Klieber)]

Thank you for your reply. I spend hours now to find out how to call an action from an Next Gen Rule script.

I’ve looked into @lewie’s helper.js and tried to load the ScriptServiceUtil:

var ScriptServiceUtil = Java.type("org.eclipse.smarthome.model.script.ScriptServiceUtil");

but also get an java.lang.ClassNotFoundException.

The following code from your documentation worked:

var myLog = Java.type("org.slf4j.LoggerFactory").getLogger("org.eclipse.smarthome.model.script.Rules");
myLog.info("Hello world!")

How can I call the Telegram action sendTelegram(String group, String message) from Next Gen Javascript?

[lewie (Helmut Lehmeyer)]

@mdk,

Have a look here: ### Example 1: Default spelling, not simplified

Here are some Examples. “Example 1” doesn’t use my my simplifying helper.js.
