Solr, Jetty, and daemons: debugging

I recently added a Solr-powered search feature to this site (using django-haystack). Rather than go to the trouble (and server resources drain) of deploying Solr via Tomcat, I decided instead to deploy it via Jetty. There's a wiki page with detailed instructions for deploying Solr with Jetty, and the wiki page also includes a link to the startup script.

The instructions seem simple enough. However, I ran into some serious problems when trying to get the startup script to work. The standard java -jar start.jar was working fine for me. But after following the instructions to the letter, and after double-checking everything, a call to:

sudo /etc/init.d/jetty start

still resulted in my getting the (incredibly unhelpful) error message:

Starting Jetty: FAILED

My server is running Ubuntu Jaunty (9.04), and from my experience, the start-stop-daemon command in doesn't work on that platform. Let me know if you've experienced the same or similar issues on other *nix flavours or on other Ubuntu versions. Your mileage may vary.
