to OpenOLAT

Hi

Because of the new features I tried to upgrade our testsystem (Ubuntu12.04) up to OpenOLAT 10.4.3. During the update I've found some information about the requirement of Tomcat8, so I've changed my update plans and firstly updateted the OS.

Now I have an fresh installed Ubuntu 15.10 server with Tomcat 8, openjdk 8 and Mysql 5.6.28. I used the "Antother installation guide" from http://www.openolat.com/fileadmin/adminwiki/_START_.html to install openolat but without any success.

Everytime I start tomcat I get the following message in catalin.out logfile:

SCHWERWIEGEND: One or more listeners failed to start. Full details will be found in the appropriate container log file

Jan 27, 2016 4:09:37 PM org.apache.catalina.core.StandardContext startInternal

SCHWERWIEGEND: Context [/openolat] startup failed due to previous errors

In the olat.log file there are no entries.

I've added the log4j.xml, olat.local.properties and the catalina.out.

Thanks for helping me.

Regards

Simon

I extended the catalina logging output by adding openolat/WEB-INF/classes/logging.properties with:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

This gives the following more output:
