Warbler 1.2.1, Rails 2.3.8 and Tomcat - RackInitializationException: no such file to load

okkezSS · October 13, 2010, 12:06am

I have a Rails 2.3.8 app that I have been building successfully with
Warbler
1.1.0 and JRuby 1.5.1. It ran great under Tomcat. I just updated to
Warbler
1.2.1, enabled the “compiled” feature in Warbler and now I’m getting the
following error in my Tomcat logs:

SEVERE: Error: unable to initialize application

I have checked, double-checked and even triple-checked that the file
it’s
complaining actually exists.

Here’s what I have installed for gems:

$ jruby -S gem list --local

*** LOCAL GEMS ***

actionmailer (2.3.8)
actionpack (2.3.8)
activerecord (2.3.8)
activeresource (2.3.8)

If I disable the “compiled” feature, it works fine. Any suggestions?

Is there a staging.class file in the
/home/myuser/apps/tomcat/apache-tomcat-6.0.26/webapps/ROOT/WEB-INF/config/environments/
path? The error message means the classloader could not find the file
and
load it properly.

I also have some issue to open the threadsafe feature with spree in
JRuby +
Tomcat. I posted a question in the jruby mail list and get a tip. It
sounds
like the spree haven’t considered the jruby and haven’t consider the
threadsafe feature. So it might lazy-load something which may break the
threadsafe mode, but I haven’t tried to change the code to see if it
works.

I guess It might also the similar issue for the compiled mode for JRuby,
it
worth a try.

Best wishes,
Stanley Xu

/home/myuser/apps/tomcat/apache-tomcat-6.0.26/webapps/ROOT/WEB-INF/config/environments/staging.class
definitely exists on disk.

And this isn’t using Spree.

Sorry I missed this thread. It’s possibly a bug in JRuby or Warbler.
Can you make a compiled war file exhibiting the behavior that you can
post to http://bugs.jruby.org?

Thanks,
