Hi Denys,


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:
* <confluence-home>/plugin-cache
* <confluence-home>/plugins-osgi-cache
* <confluence-home>/plugins-temp
* <confluence-home>/bundled-plugins
* <confluence-home>/bundled-plugins_language
* Startup Confluence

I hope this helps.

Cheers,

WZ

William,

It was related with wrong DBHOSTNAME in confluence.cfg.xml

Thanks for the idea about database.

With BR,

Denys.

The first folder mentioned is named plugins-cache (not plugin-cache!)

Thank you for showing me I wasn't alone. For me it was:

  • Atlassian has upgraded the web.xml file in Confluence 5.4 (that's right, that's their job ;))
  • I had applied changes to this file to implement HTTPS,
  • I had incorrectly overwritten their changes.

I've reset the file and restarted, it works. Hope it'll help someone.
