JRule - openHAB Rules using Java

Here you can find the console output when I installed JRule from the marketplace. No errors.

I can try to reproduce this on my openHAB instance earliest around the 20th.

I appreciate it!

After reverting to OH 4.1.3, I discovered that the console output after installing JRule on OH 4.2.0 is missing the following lines:

21:49:04.755 [INFO ] [n.jrule.internal.handler.JRuleHandler] - Instantiated JRuleActions class

Uploading the pre-compiled JAR to the right folder on OH 4.1.3 triggers JRule to load it immediately.

Are your rule classes in the correct package? Ran into a similar issue where rules would not get loaded because I put them in my own package. You need to put them into org.openhab.automation.jrule.rules.user or add org.openhab.automation.jrule.package=your.package into jrule.conf

nelson.aponte · August 11, 2024, 7:46pm

Yes, the rules are under

org.openhab.automation.jrule.rules.user

They are the same rules I was running with OH 4.1.3, just they didn’t work right after I upgraded to 4.2.0.

What I think the issue is (check my previous comment), is that JRule is not fully loaded. I’ve no idea what is blocking it. I don’t know what log would report the issue, as I don’t see anything in the standard ones.

lsiepel · August 14, 2024, 11:44am

Good lead is that
Instantiated JRuleActions class
Is missing in 4.2.1. I did not check the source code, but before this and after
Instantiated JRuleThings class I expect something to be loaded (dependency or something) that is not there.

This shows that it is very lickely not related to the rule, but binding/dependency/framework related.

nelson.aponte · August 16, 2024, 9:13am

It’s odd that the problem is related to the binding/dependency/framework, keeping in mind @Seaside 's comment:

@lsiepel, did you install JRule on OH 4.2.0 and have the same problem?

lsiepel · August 16, 2024, 9:40am

I’ll be able to check Sunday or Monday.

Downloaded the BETA21, dropped it in the addon folder and all seems fine:

So now i’m confused, there must be something specific to your setup that prevents this rule addon to load correctly.

Note that i have no rules setup.

I guess we need to remove parts of your setup to determine the cause.
Do you have other addons installed? Could you list them and/or temporary uninstall them, to be sure there is not something else
Have you made any changes to configuration files in the userdata folder?

nelson.aponte · August 21, 2024, 7:38am

Huh, those are not good news

Let’s start with the basics. I upgraded to OH 4.2.0 stable from 4.1.3 using dnf, as I’ve done since 2.X.
OH runs with OpenJDK 64-Bit Server VM (Red_Hat-17.0.6.0.10-3.el9) (build 17.0.6+10-LTS) in a Raspberry Pi 4B (ARM64) / 4G RAM with CentOS 9 (64-bits).

I have the following add ons:

Astro
Netatmo
System Info
UniFi
Hue
OpenWeatherMap
Cloud Connector
Telegram
UPnP (I’m not sure I had this one in 4.2.0, but it’s currently installed in 4.1.3)
iRobot
Sonos
TP-Link Smart Home
Roku
Mary Text-to-Speech

Manually installed:

TapoControl
Yale/August smart locks

For automation, I only use JRule and 1 or 2 old DSL rules that are not yet fully supported by JRule.

I guess I will have to run a clean installation of 4.2.0, install JRule first, and check. I’ll try to do that this week.

@lsiepel, by this do you mean the /etc/openhab/ folder or /var/lib/openhab/config? I don’t think I have changed anything under /var/…

nelson.aponte · August 25, 2024, 6:03pm

Hi, @lsiepel.

I upgraded from 4.1.3 to 4.2.1 and JRule loaded successfully. Maybe whatever was messed up with my configuration got fixed after I uninstalled OH and clean-installed 4.1.3.

Thank you for your help!
