Summary: Root cause of failure during rails initialization is lost
Initial Comment:
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 i
s complete.

Hello all,
I'm trying to deploy a Rails 2.0.2 app to Jruby. I'm using Warbler .9.2,
Goldspike 1.5 snapshot, and Jruby 1.1RC1 (I've also tried 1.0.3). The war
looks good. All my gems are present. I can view the Rails index.html page.
But I can't see any of the dynamic pages. Tomcat returns:
503 The server is currently overloaded, please try again later
In the log files, I see the following error:
javax.servlet.ServletException: Could not load Rails.
See the logs for more details.

Is this a configuration that generate a working war file? If not, what is
the recommended configuration for Rails 2? I know support of Rails 2 isn't
solid yet, but it seems like some people have been successful.
Is the error meaningful to anyone?
Can you look a bit further up in the log file to see if there's a Ruby message?

Message:
I think the problem is that the exception detail is going to the web app
logger, but the ServletException is being shown on the Tomcat central log.
If a logger is configured for the context then the messages would likely end up
there, but looking at the newer versions of Tomcat, this doesn't appear to
happen by default.
I'll need to do some testing to confirm this, but if it's the case, then we can
have Warbler add a default context file for Tomcat to the war, which includes a
logger.
