OpenEMM Technical Support Forum

I have a clean OpenEmm setup.
If i click on 'mailings' it shows me an empty page with an error 500 in the logs.


jakarta.servlet.error.status_code: 500

jakarta.servlet.ServletException: jakarta.servlet.jsp.JspException: ServletException in '/WEB-INF/jsp/mailing/overview/mailing-list.jsp': java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.jsp.mailing.overview.mailing_002dlist_jsp

How do i get this work?

The OpenEmm status inside the OMT shows the following errors:

Frontend application integrity: ERROR
Statistics application integrity: ERROR
Webservices application integrity: ERROR


What needs to be done here?

Hi,

these errors are new in 22.10.025 and 23.04.016 and look like a cosmetic bug

I checked the phyton module, i am not a python programmer, but here is my insight

OpenEMM does some sort of environment check in CheckMenu.py for the environment.
The script checks for the presence of some env variables like

Environment.isEmmFrontendServer
..
Environment.isOpenEmmServer

And if they are not present, we get this errors or the checksum for the folder that are checked is wrong.

I think that the runtime installers are not tested before they get published, some environment var are not set.
Even the documentation seems to work only for the older Linux releases.

Some of the required files are missing during installation and if you check catalina.out you will find errors about missing asset files under

FileNotFoundException: /home/openemm/release/emm/openemm-gui-23.04.000.116/assets/sass/boot/variables.scss

But we need to wait for a new runtime release...

OpenEMM 23.04 is a alpha version, it is not even listed as beta in the OpenEMM wiki yet (https://wiki.openemm.org). The version was mistakenly uploaded to the release channel. I just removed it.

Thanks,

But the error is still present is in 22.10.000.222

Frontend application integrity: ERROR
Statistics application integrity: ERROR
Webservices application integrity: ERROR

And Database is already on Alpha Version 23.01.436

The integrity check is not available in 22.10.

Can i hide the integrity check error messages?

No, but the output will be removed in a later runtime release.

New runtime is available: 22.10.027
