No such file to load -- rack when booting JRuby 1.6.0RC1 Rails app in Tomcat

Same environment, same error.

More info: it happens using "bundle install" or "bundle install --deployment". Could be warbler the problem? I'm using warbler (1.2.1).

RackInitializationException: no suck file to load --rack from file: c:/tomcat/webapps/bestsales/WEB-INF/lib/jruby-rack-1.0.5.jar!/vendor/rack.rb:7
...
caused by RaiseException: no such file to load – rack

Probably related: JRUBY-4353.

This is related to JRUBY-5281 which unfortunately was in RC1 but is now fixed.

Note that JRuby-Rack 1.0.5 also has this bug, make sure and use JRuby-Rack 1.0.6 along with JRuby 1.6.0.RC2.

In my machine(where I generated this war file):
> gem list
...
jruby-jars (1.6.0.rc1)
jruby-launcher (1.0.5 java)
jruby-openssl (0.7.3)
jruby-rack (1.0.6.rc1)
...

ps: when you deploy a .war file to tomcat 6, it automatically decompress to a folder with the same war name.

Just tried using jruby-rack-1.0.6.rc1.jar and http://ci.jruby.org/snapshots/jruby-complete-1.6.0.RC1.jar. Same error:

Just found the root cause of this problem. My Tomcat installation path (as well as Robert's) contain white spaces. The error doesn't happen if I install tomcat in c:/tomcat directly.

Right, in that sense it's the same problem as JRUBY-5281. This is supposed to be fixed in RC2 and I fixed it in the JRuby-Rack 1.0.6.rc1 release yesterday. So, my question is why you're still seeing it? Did I fix the bug incorrectly or are the fixes not taking effect in your environment for some reason?

I think that there's still an issue with spaces and accents. I did not figure-out exactly what happens yet.

I've been looking at test_jar_complete.rb and it seems that, when I try adding a test for paths with accents, there's an error at building the correct dirname. As an example, when trying to build the dir "hi_é" with an "é" UTF-8 (0xc3a9) the test process will actually build "hi_é" with an "é" MacRoman (0x89). As a result, when trying to copy the complete jar to the target dir (i.e., a path with UTF-8 accent), the dir is not found and the test fails on an Errno:ENOENT exception.

It led me to think that there might be another bug in strings/paths handling which shadows the tests in test_jar_complete.rb

If I'm not clear, somehow, I'll try to reproduce this tomorrow after a pull and I'll push my updates on the test cases in my github tomorrow (I only have http:80 here).

I fixed a problem with loading files that have no-ASCII characters in them just a bit ago. Maybe it will have helped?

Charles, just got jruby master code, generated a new jruby jar and replaced the RC1. Same error:

Reopening since users report it's still broken.

I tried warbling my app with the latest jruby-jars 1.6.0.rc2 and jruby-rack 1.0.6.rc1 (--pre). Still getting the same error.

I re-resolved JRUBY-5281 since it addressed only standalone jruby-complete, which appears to work fine. So the additional issues should be tracked here.

Also getting the same error with jruby-jars 1.6.2.rc2 and jruby-rack 1.0.6 (final).

Hopefully this is fixed once and for all in 196873c.

Nick, I just recompiled jruby (rvm install jruby-head), built the new jruby-jars, installed jruby-rack 1.0.6 final, made sure Gemfile was using the proper versions... everything is working perfectly now. My issue was specifically tied to the spaces and it works perfectly now. Thank you for the update and work. Looking forward to JRuby 1.6.0 final.

I confirm it works with my setup as well on MacOS: (cf.
https://github.com/lucasdicioccio/windows-jar-issue-with-spaces )
Will try on Windows later and re-comment.

Verified on WindowsXP, it works well. I've tried with path with spaces and accents. Thanks a lot !
