Hi,

we are trying to move from the (deprecated) goldspike rails plugin to  
the new warbler gem to create a war file from our RoR application, but I  
cannot get the war file to run.

Everything seems to be OK, all needed gems (especially ruby-net-ldap)  
are packaged in the right places.

Tomcat and the application startup fine, I can access my login screen.  
Authentication is done agains a LDAP server but when my app tries to  
contact the LDAP server, it throws an error:

“no such file to load – net/ldap”

but the gem is part of the war file and is located in the same place as  
all the other gems (rails, jdbc-adapter etc)

I’m using JRuby 1.1RC2 and warbler 0.9.4

I wouldn’t be that confused if it failed to load /any/ gem, but it seems  
to be limited to the ldap gem as the rails gems and the  
activerecord-jdbc-adapter are loaded fine (and are working)

Any ideas? What am I missing here?

Any help is greatly appreciated

Thanks in advance  
Thomas

net/ldap is native code, so you can’t run that on jruby yet.  
My guess is you’d need to call out to JNDI if you wanted to talk to  
LDAP on JRuby.

jruby-ldap-net is running fine from within NetBeans with JRuby 1.1 and  
it’s running fine when beeing packed with the old goldspike plugin…

Hi Nick, thanks for your answer.

Sorry for the confusion, I’m using ruby-net-ldap (no J involved here)

I tried Warbler 0.9.4 and Warbler 0.9.5 none of them worked.

Follow-up:

I found this piece of code on the JRuby Wiki pages to detect all needed  
gems:

BUILD\_GEMS = %w(warbler rake rcov)  
for gem in Gem.loaded\_specs.values  
next if BUILD\_GEMS.include?(gem.name)  
config.gems[gem.name] = gem.version.version  
end

interesting enough this does not include ruby-net-ldap as well.

So what’s so special about this gem?

(Btw: I have tried using jruby-ldap as well, but that broke our code)

Are you using jruby-ldap or ruby-net-ldap?  
([Ola Bini: Programming Language Synchronicity: Announcing JRuby/LDAP](http://ola-bini.blogspot.com/2007/10/announcing-jrubyldap.html))

There was a bug w/ gems that had native components that was fixed in  
Warbler 0.9.4. Maybe you could try that.

I was finally able to get this to run:

I upgraded to JRuby 1.1RC3 (for running “warble”) and replaced the  
jruby-complete-1.1RC2.jar and goldspike-1.5.jar in the Warbler’s lib  
directory with jruby-complete-1.1RC3.jar and goldspike-1.6.jar.

Now everythings seems to be working fine.

Could you file a bug about this, ideally with a reproducible test case  
or app?

[http://jira.codehaus.org/browse/JRUBY](http://jira.codehaus.org/browse/JRUBY)

It would also help if you could hunt us down on the mailing list or on  
FreeNode IRC in #jruby…we’re standing by to help with this sort of  
thing.
