<confluence_install>/log/catalina.outand check last events being logged
- If you observe
Unable to load server configuration fromWARNING, then tomcat is failing to load due to configuration error
- WARNING will also indicate which file is misconfigured, in the example error above,
Tomcat needs correctly defined configuration in server.xml and other files in order to boot and load Confluence.
Go to location in the specified file indicated by
column values in the error message. Issue might be with incorrect declaration or simply missing character.
You can also use new Confluence installation of the same version for reference for default configuration or content of certain system files.
Error above indicated failure in
Error at line  column 
Looking at server.xml, we can see that tomcat failed to recognise and load specified context declaration, because it was made incorrectly. Declaration added within its own
<Context> ... </Context> tags, as opposed to being added within the existing
<Context > ... </Context> tags. Removing or correcting declaration allowed for correct boot.
