NULLPointer on startup

I just installed Confluence on Ubuntu 16.04.
After installation an error is reported on the browser without any specifications of the problem.
In the logfile I found the following StackTrace:
2017-11-11 22:21:15,083 ERROR [http-nio-8090-exec-4] [[Standalone].[localhost].[/].[johnson-data-servlet]] log Servlet.service() for servlet [johnson-data-servlet] in context with path [] threw exception

Hi Florian,

Usually those NullPointers are generic, and doesn't give a full picture of the problem. May I ask you, if you can reach Confluence's database through Confluence's box?

To rule out a problem with the plugins during the startup, can you please do the following steps to clean the plugin cache?

* Shutdown Confluence
Delete the content from the following folders:
* Startup Confluence

And better way is read

OR double check you config files like,,, server.xml, confluence.db.xml. and check owners for home and installation directories

I hope this helps.

thanks for your fast answer. It worked fine.

The main problem were insuffizient provided CPUs by the hoster, which caused that many errors.

Best wishes,
