In some cases, you might want to run WorldServer in the foreground. For example, to obtain debug information or if SDL Technical Support requests a stack trace.
Procedure
Go to the apache-tomcat-8.0.36/bin folder.
Run the following command:
> catalina.sh run
This starts WorldServer and gives you access to debugging information.
Press Ctrl-\.
A stack trace is printed, along with any existing application messages.
