OpenEMM 19.10 does not work with Java 11. You should use a later version of OpenEMM.

Sounds good. Which version of MariaDB do you use and which source did you use to get the packages?

Which operating system do you use?

What do we have to do to reproduce the error in catalina.out?

Please update to 23.10.000.170, maybe this already helps.

We just tried with

$ git clone https://github.com/agnitas-org/openemm
$ cd openemm/backend
$ chmod 755 build-backend.py
$ ./build-backend.py

and it worked.

Which operating system do you use to build the executable code of OpenEMM?

Tomcat and Tomcat Native are two different things. Of course, you need Tomcat to run the OpenEMM frontend.

I recommend to not rely on dubious "online resources" but to use https://wiki.openemm.org as the source of truth regarding OpenEMM.

I could not find the location where the Install&Admin guide lists Tomcat Native as required, please advice.

And where did you find references mentioning "OpenEMMInstaller.sh"? This has been replaced by OMT.sh a long time ago.

Which operating system and DBMS do you use?

We just published the first GA (general availability) version of OpenEMM 24.04. What is new in OpenEMM 24.04? Have a look: https://wiki.openemm.org/lib/exe/fetch.php?media=agnitas-openemm-neuerungen-version-24.04-en.pdf (German version: https://wiki.openemm.org/lib/exe/fetch.php?media=agnitas-openem...

Tomcat-Native is legacy (see Install & Admin Guide), you do not need it. The official guides are here: https://wiki.openemm.org/

The first BETA of OpenEMM 24.04 is available now! Please download and check it out. We are ready to fix any bug you can find. For updates use OMT, for a fresh download of the new runtime package use https://share.agnitas.de/index.php/s/xQ7Ccxc7xj4RGYr/download See OpenEMM Wiki at https://wiki.openem...

Some OpenEMM users do not want to use nodejs or are not allowed to use it. Therefore, we kept wkhtmltox as an alternative.

Thanks for notification, the footer of the document is updated now.
