Locale error when running Unicorn locally

[viking@…]

Hi,

I followed the (somewhat sparse) instructions on installing Unicorn in order to run it locally. However, when I visit  http://localhost:8080/unicorn/init, I get this error:

SEVERE: Servlet.service() for servlet Init threw exception

The defaultLocale appears to be null. Any tips are greatly appreciated.

TIA, Jeremy

I should mention that I'm using tomcat6 on Ubuntu 10.04, using the mercurial trunk (changeset 1459:d7199abe8789)

You might be not configure tomcat correctly or you might not have admin control on ur machine only admin control has the permission to run it

It happens if Unicorn is not initialzed correctly. You should check the logs under WEB-INF/logs. Most likely you'll see "Unicorn config file "unicorn.properties" could not be found in classpath.". Please referer to http://code.w3.org/unicorn/wiki/Documentation/Install to correctly build Unicorn. Anyway I fixed this exception to show a more intelligible message.
