Comments on Java test-drive

You must mention that you’re using Windows and you have hit a Windows specific problem with nrjavaserial that does not exist as such on Linux hence not on openHABian. Please help keeping communication clean and don’t cross-post into every related thread just because you’re frustrated.
I understand that but it isn’t helpful.

Just changed the JAVA version. So far everything seems to run very well. Many thanks @mstormi for paving the road for OH3 :+1:

You “must” read my comments before you judge anything and I’m very polite now. Java on non-openHABian
Not mentioning that I’ve shared complete debug logging etc.
If I would receive useful information would be helpful.
I was not frustrated at all up till now and I do not give up.
I would like to change to Java 11 still.

So now my system runs on java version “1.8.0_231”
Java™ SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot™ 64-Bit Server VM (build 25.231-b11, mixed mode)
Operating system windows10 and it runs on Intel NUC I7 8gb ram + ssd
openHAB 2.5.6 Build #139
I can start Openhab only with start.bat. It does not start as a service.
I get the following messages in karaf consol:
karafconsollog.txt (5.8 KB)
I use these bundles:
bundle_list.txt (19.9 KB)
DSL rules are working fine but NGRE rule engine does not start.
ruleengine.txt (5.0 KB)
I found another error log in userdata\catch folder: 1591735354178.log (2.6 KB)
It would be helpful to have a hint what I need to check for running Openhab as a service.
Tomorrow I try to fix NGRE rule engine.

Off topic, this thread is about openHABian not openHAB on windows.

No. It means: please use a separate thread for your problem and don’t post into others’ threads unless you contribute to what’s the topic there.
The Java test-drive is on openHABian which is Linux ONLY as can be read in the original post.
This thread is just comments on that, so your posts do not belong here.
Hence also my request to keep communications clean.
As a moderator, I’m asking you to follow the community guidelines. Thank you for your cooperation.

Ok, as you wish.
Sorry I was reading it fast.

I just installed the 32bit version on pi3. Working like a champ!!

I like the new openhabian changes, repo related that is!

Question, can the 64bit be used on buster? Is there an advantage?

You mean 64 bit Java on a standard 32 bit OS ?
See README.
I guess it would work, but it’s neither tested nor recommended as it has nothing but disadvantages (larger memory consumption), that’s why openHABian refuses to install it like that.

@mstormi That is what I meant 64bit on 32bit OS. I went with 32bit as the most valid assumption for the 32bit OS, I picked correct. Thanks for info, missed the info the first time.

Hi,
anyone experienced issues with the systeminfo binding, or is it just me?

I’m running on openhabian snapshot #141 with Zulu 32bit Java11 on a RPi4

The systeminfo thing is online, but i dont get item updates…

I set the log to DEBUG… but i dont get any error messages…

I have no problems running that under Zulu 11.

okay… good to know… will have a look what causes my systeminfo items to stop.

Now i tried ist again in a Debian VM on my synology. Used the master Branch and tried to switch ti Zulu 11 32 Bit. Got the following errors:

Error are made with the debug option on

Hmmm., What distro are you on i.e. what does cat /etc/os-release return. I think it might not have all of the preinstalled packages, did you run the unattended setup before trying to install Zulu11? I believe it is because zlib is not installed on your system.

Result of the cat command is

PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

and as far as i know the zlib is part of the zliblg and this package is upto date

zlib1g ist schon die neueste Version (1:1.2.11.dfsg-1).

At the end it is a plain debian where i installed openhabian with wget an made the steps i reuire.

Your wrote that you tried to switch to Zulu 11 32 Bit
and that Zlib is installed

is it the 32bit or 64bit library ?

In case you use java based on 32bit you also need to install related 32bit libraries.

I tried Zulu 11 64 Bit als well and it did not work

same or an other error message ?

Sorry, but did not looked at the error, because i had not the time to check that carefully. After teh first error it was my goal to bring openHAB online again
