OpenEMM-Application is NOT running

[mister]

I finally got OpenEMM to start but still am unable to launch it from my URL (Server Not Found). I've updated it to the latest package and can't find any errors. Please help.

[moechsner]

hy, the OpenEMM Server is started?

have you open the ports and forwarded in the firewall from 80 to 8080?
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-forward-port=port=80:proto=tcp:toport=8080 --permanent

A tip from me, set up the routing only on a standalone server

When you have opened the Port 8080 than you can test with

URL:8080

[mister]

Thanks Moechner,

Both were already opened and I still can't get in. I've tried several browsers and still get "server not fund". I've tried with Https and HTTP same result.

[root@markfeldmaninsurance ~]# firewall-cmd --zone=public --add-port=8080/tcp -- permanent
Warning: ALREADY_ENABLED: 8080:tcp
success
[root@markfeldmaninsurance ~]# firewall-cmd --zone=public --add-forward-port=por t=80:proto=tcp:toport=8080 --permanent
Warning: ALREADY_ENABLED: 80:tcp:8080:
success

[maschoff]

When you restart OpenEMM, check the log file catalina.out of Tomcat in /home/openemm/logs for error messages.

If Tomcat fails to start OpenEMM properly, you can not access the login page.

I am pretty new to this and do not know what I am looking for. Here is the emm.log - let me know if you have any idea what is wrong? Thanks for your help.

[maschoff]

To me it looks like you did not execute all jobs described in the OpenEMM wiki in chapter "5 Configuration", section "OpenEMMInstaller", because the log shows that some configuration values like "system.url" are missing.

[mister]

I still can't get it to work and am about to give up. Let me know if there is anything else I can do to get this to work. I appreciate your help.

The causing error message is still there:

Could it be that you have modified Tomcat's configuration or you try to run a 2nd app with Tomcat in parallel to OpenEMM?

[mister]

I appreciate your help - I am not a programmer and do not know how to figure this out. Can you tell me how to determine that?

Hello,

when starting OpenEMM we get the following error:

What can we do?

Thanks, Please Advice for any help.

[maschoff]

"OpenEMMApplication is NOT running": You should do a restart.

[Manoj Sreepada]

Hi,

After Restart the OpenEMM we get the following error:

No Tomcat process is running
once : ok
mailout : running
update : running
trigger : running
generate : running
mta : running (running)
pickdist : running
slrtscn : running
direct-path : running
bav-update : running
bavd : running
bav : running
mlcontrol : running

What can we do?

Thanks,

[maschoff]

Looks like OpenEMMInstaller was not able to start Tomcat. Please have a look at Tomcat's log catalina.out to check for error messages.
