Cause

  • If you are running 0.6.2, you may have specified your db connection settings directly in resource/xplanner.properties. A bug in 0.6.2 build system makes it only look in resource/xplanner-custom.properties. Specify your db connection settings in resource/xplanner-custom.properties instead.
  • Otherwise, check your connection settings. This exception indicates that xplanner could not create a connection.

Causes

/etc/hosts is wrong. It had

/etc/hosts
127.0.0.1       localhost       localhost.localdomain

It should be

/etc/hosts
127.0.0.1       localhost
