Tomcat: One or more listeners failed to start

Question

I have an application which is not starting up after I added/upgraded some dependencies. It logs an error saying

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

I saw all the log files, and catalina., localhost., application.*, but none of them seem to have the stacktrace because of which the startup is breaking.

This is tomcat8, java8.

How do I check the logs and where can the logs go other than the normal tomcat folder.

Catalina logs:

Answer 1

Found a simple way to identify the problem.

1. In your WEB-INF/classes directory of the application, make a new file: logging.properties.

2. Add the following in that file:

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

3. Restart tomcat.

Now you'll have the complete stacktrace and debug the problem from there on.

For a Maven Build

1. Create a new logging.properties in the src/main/resources directory of the module
2. Add these entries into that new file

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

3. Run mvn clean install
4. Restart Tomcat
