I also ran into this when I was getting started deploying into
Tomcat. Anytime there was a problem during rails initialization I'd
see that error looping in the logs. Contrary to the 'See the logs for
more details' message I couldn't find any additional logging
information in the server log(catalina.out) or any of the rails log
files. As a quick fix I wound up applying the patch below to rails-
integration to print the stack trace which did show me the underlying
problem which was usually obvious once I could see full stack trace
(In one case it was that I was developing on a Mac which was
shielding some case sensitivity typos in require statements). I could
swear I tried passing the original exception to the (String msg,
Throwable rootCause) constructor of ServletException but that didn't
dump the entire stack trace to the logs. Anyway, I think there is an
issue with Goldspike swallowing exceptions. I'm guessing the Rails
logging isn't usable before the Rails initialization is complete.

Tomcat. Anytime there was a problem during rails initialization I'd
see that error looping in the logs. Contrary to the 'See the logs for
more details' message I couldn't find any additional logging
information in the server log(catalina.out) or any of the rails log
files. As a quick fix I wound up applying the patch below to rails-
