Forum: JRuby 500 Error Misbehavior in Servlet Containers

Hi Folks,

FWIW: ruby -v = jruby 1.6.7.2 (ruby-1.9.2-p312) (2012-05-01 26e08ba)
(OpenJDK 64-Bit Server VM 1.6.0_24) [linux-amd64-java]

I'm working on custom 404/500 error messages in my Rails 3.2 app, but
first, I seem to be getting buggy behavior with standard error messages.

In WEBrick, everything behaves as expected: I get an error message in 
the
browser.

On GlassFish, when a 500 error is encountered (triggered, for instance, 
by
<%= nonexistent_var %> in a view), the error *is* recorded in the
server.log; however, no response seems to be returned to the browser.

Here's the same thing with wget:

Do I need to file a bug?

Thanks,
Jamie

Filed a bug:  https://jira.codehaus.org/browse/JRUBY-6897

Have you checked to ensure there's not some GlassFish configuration 
setting that would hide the 500 error from the user?

Have you tested this application in another JRuby web server to see if 
it's a JRuby bug or something specific to GlassFish?

Hi Ben,

> Have you tested this application in another JRuby web server to see if

I know it works under JRuby in WEBrick, but did you mean another servlet
container? I can try Tomcat now.

Thanks,
Jamie

500s seem to behave the same way in Tomcat7.
