Forum: JRuby problems deploying to weblogic 10.3 and tomcat on Solaris

Hello,

I developed a very simple hello world jruby application using rails 3.2,
jruby 1.6.7, and warbler 1.3.2.  When I deploy the application to my
local Weblogic Server, everything works great; however, when I then try
to deploy to our development weblogic server, which is running on
Solaris 10, I get the following error.  I’ve also tried using rails
3.0.10 and also a tomcat server, with the same results.  To me, it looks
like it can’t find the core rails libraries.  Has anyone come across
this issue before?  Any help would be greatly appreciated.  I’m very
much stuck at this point:

I assume where you have "Path to weblogic staging 
dir/hello3/hello3/WEB-INF/gems",  you've substituted "Path to weblogic 
staging dir" for the actual path of the exploded war?  Have you taken a 
look in that directory? what do you see?

When you run `jar tvf hello3.war` (or whatever) do you see all your gems 
in the WEB-INF/gems/gems dir?

Can you gist your warbler.conf?

Yes, I substituted the actual path.  Sorry - probably should have
mentioned that...

Initially, the app was not deployed as an exploded war, so the path only
contained the war file.  I then deployed it as an exploded war and
verified the gem.path and gem.dir paths were correct and the gems were
located in these directories.  Unfortunately, it did not fix the issue.
The war file also contained the gems in the correct directory
(WEB-INF/gems/gems).

My warbler.rb file contains two entries:

config.dirs = %w(app config lib log vendor tmp)
config.webinf_files += FileList["config/weblogic.xml")

It’s strange that the app runs without issue from my local weblogic
server but not when I deploy it to weblogic or tomcat running on
Solaris.  Could this be a java.home issue?  Do I need to explicity set
this variable?

Thanks for the help!!

Here's the gist link to the warble.rb config file:

Is anyone running weblogic 10.3.x or tomcat 7 on solaris 10 that could 
test a simple hello world app?  If it works for you, then it must be 
something in my environment.

Jeff, were you able to solve this? I'm running into the same "no such
file to load -- rails/railtie" problem deploying to Apache Tomcat on
Solaris with Rails 3.1.3, jRuby 1.6.6 & Warbler 1.3.2

I'm Jeff's coworker (he's out this week) but I can give you a partial
answer.

After trying many combinations of Ruby, Rails, warbler, and rack, and
nearly giving up, we found a combination that works. We are using Rails
3.2.2, JRuby 1.6.5.1, and the latest warbler, but we had to downgrade
jruby-rack to 1.1.5 I believe.

What doesn't work is asset compilation, because we haven't found a
working javascript runtime. Node.js doesn't support Solaris Sparc, and
therubyracer had compilation issues we didn't spend too much time trying
to resolve. So we currently precompile assets on local development
workstations (Windows). We're not really using the asset pipeline (and
I'm not convinced it was a good idea to make it the Rails default), so
we may disable it so that we can run a CI build on Solaris.

JRuby 1.6.6 definitely didn't work at all. I'm really hoping the JRuby
team spends the time to make 1.7 solid on Solaris. Otherwise we'll have
to expedite our transition to Linux...

- Mark.

Also, make sure that you have the correct jruby-jars gem loaded.  It 
should be 1.6.5, not  1.6.7 or higher.
