JRoR (JRuby 1.1.6) app. cannot load rubygems

weyus · January 2, 2009, 10:31pm

All,

JRuby 1.1.6
Websphere 6.1

I have a Rails app. that is packaged as a WAR file using Goldspike
1.6.1.

When I try to start this app., I get an error that Rubygems can’t be
loaded:

“Rails requires RubyGems >= 0.9.4. Please install RubyGems and try
again: http://rubygems.rubyforge.org”

I have verified that RubyGems appears to be in the jruby-complete-1.6.1
JAR file located in WEB-INF/lib of my application. See below:

$ jar tvf jruby-complete-1.1.6.jar | grep rubygems

Anyone know why my Rails infrastructure can’t see rubygems?

Thanks,
Wes

Is there a reason you still need to use GoldSpike? To be honest I’m not
surprised it’s fallen behind…GoldSpike hasn’t been updated in almost a
year, and has been widely superceded by Warbler. Were you the one using
GoldSpike because you’re wiring into some existing servlet stuff?

As for why it can’t find it…I don’t know. We juggled around some
require logic and removed some support for odd jruby home locations
(like ~/.jruby) so perhaps one of those things caused a problem. I
presume this worked with 1.1.5?

I was the one using some existing servlet stuff. Frankly, I spent so
much time trying (and failing) to get some apps. working with Warbler
that I got soured on it. I suppose I could try once more.

AFAIK, the last time it worked was 1.1.3. With 1.1.4, I get an error
finding the engines plugin. I should also try 1.1.5 - it was failing
because of an error on my part.

Seems like Goldspike woudn’t have anything to do with how rubygems
itself is found though right?

1.1.5 gives me this - which is weird…

Ahh, IBM JDK. I don’t know why it does this, I see it in test runs too.
It doesn’t appear to break anything though. Does this actually prevent
something from deploying?

Oh arse! - it deployed fine, but I just assumed it wouldn’t work - the
error being all scary and stuff :). I’ll see if I can run the app.

Thanks for the help - very much appreciated.

Yeah, I need to figure out where that’s coming from, but at least it’s
not fatal.

Well yes and no. It’s possible GoldSpike depended on old bugs in our
require/load path searching that have been fixed. It’s possible it
expected .jruby support to be intact and that it may have been using a
.jruby dir of yours instead. And it’s possible GoldSpike has just
bitrotted…we’ve changed a lot over the past year.

If there’s anything that would make it easier to use Warbler, we should
discuss that. I don’t believe anyone’s maintaining GoldSpike, and
whatever features you need we should try to migrate over.
