Question

Where can I find error logs for Tomcat?

Answer

Tomcat maintains verbose access and error logs.

When a problem occurs in WebVoyage, a number of logs will be updated with the Java errors. These logs are particularly useful when troubleshooting problems that occur as a result of customizing WebVoyage.

If you encounter the error_500.html page, check the Tomcat logs at: /m1/voyager/xxxdb/tomcat/logs
The useful file to check will be catalina.out logs. Amidst the long list of java errors, look for the messages around “Root Cause” and “Caused by:” lines. You can, at times, get very clear feedback such as ‘The string "--" is not permitted within comments.’ Errors like these will get you started tracking down the source of the problem.

Additional Information

See WebVoyage System Error when trying to add customization to WebVoyage for examples of errors and how to interpret them.
