JRuby 1.3.0 issue with warbler

Ruby JRuby
1

I have trouble to use jruby 1.3.0 with warbler. If I create a war file
with
jruby 1.2.0, all succeed:

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ jruby -v
jruby 1.2.0 (ruby 1.8.6 patchlevel 287) (2009-03-16 rev 9419)
[i386-java]

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ jruby -S warble war
mkdir -p tmp/war/WEB-INF
jar cf carrierDB.war -C tmp/war .

But If I upgrade to jruby 1.3.0 (switch my ‘jruby’ link from
‘jruby-1.2.0’
to ‘jruby-1.3.0’), the ‘warble’ command is unknow:

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ jruby -v
jruby 1.3.0 (ruby 1.8.6p287) (2009-06-03 5dc2e22) (Java HotSpot™
Client
VM 1.5.0_16) [i386-java]

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ jruby -S warble war
jruby: No such file, directory, or command – warble

Any idea what is wrong?

My environment is:

System Version: Mac OS X 10.4.11 (8S2167)

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ java -version
java version “1.5.0_16”
Java™ 2 Runtime Environment, Standard Edition (build
1.5.0_16-b06-275)
Java HotSpot™ Client VM (build 1.5.0_16-132, mixed mode, sharing)

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ echo $JRUBY_HOME
/opt/local/jruby

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ echo $GEM_HOME
/opt/local/gem

Cheers,
Christian

you likely need to install warble again in your jruby-1.3.0
installation. Did you run jruby -S gem install warbler after changing
your symlink to jruby-1.3.0 ?

Hi Adam!

Thank you for your quick replay.
I don’t install warbler again, because my GEM_HOME directory is outside
my
JRUBY_HOME directory (see my first mail). If I list all installed gems,
warbler will be listed:

chris:~ mullerc$ jruby -S gem list

Any idea?

Hi Hiro!

The ‘warble’ script dosn’t exist in my jruby-1.2.0/bin directry.

After I uninstalled warbler (all versions) and installed warbler again,
the
‘warble’ script dosn’t exist in my jruby-1.3.0/bin directry. If I call
‘jruby -S warble war’, I receive the same error:
chris:~/workspaceExtJs/carrierDB2.0 mullerc$ jruby -S warble war
jruby: No such file, directory, or command – warble

But the ‘warble’ script exists under ‘/opt/local/gem/bin’

chris:~/workspaceExtJs/carrierDB2.0 mullerc$ which warble
/opt/local/gem/bin/warble

If I change my JRUBY_HOME back to jruby-1.2.0 and call ‘jruby -S warble
war’, it works…

Is this a JRuby installed from a package, like from macports or apt-get
or something? In general the scripts for a gem are always installed
under /bin, so this other location seems pretty unusual.

Christian,

warbler gem puts the ‘warble’ script in the same directory as the
‘jruby’ script. It’s not in the 1.3.0 directory. Re-install warbler,
as Adam suggested.

Note- I used this technique to include jruby 1.3.0 and jruby-rack with
warbler using jruby 1.3.0 and it worked fine in OS X and linux:

from
ttp://stufftohelpyouout.blogspot.com/2009/06/how-to-get-warbler-to-include-custom.html

  How to Get Warbler to Include a Custom Version of JRuby and
  JRuby-rack
  <http://stufftohelpyouout.blogspot.com/2009/06/how-to-get-warbler-to-include-custom.html>

If you want to use your own jruby-complete and jruby-rack jars in your
project, here’s how to do it, thanks to Nick S. for example of how
to change the rack version.

In warble.rb, change this section so it looks like this: ||

Additional Java .jar files to include. Note that if .jar files are

placed

in lib (and not otherwise excluded) then they need not be mentioned

here.

JRuby and JRuby-Rack are pre-loaded in this list. Be sure to include

your

own versions if you directly set the value

config.java_libs += FileList[“lib/java/*.jar”]

config.java_libs.delete_if {|f| f =~ /jruby-rack/ || f =~
/jruby-complete/ }
config.java_libs += FileList[“lib/jruby-complete*.jar”]
config.java_libs += FileList[“lib/jruby-rack*.jar”]

That will let you put your own version of jruby rack and jruby complete
into your lib/ dir.

Then get and build jruby via git clone git://github.com/jruby/jruby.git.
You’ll need Ant http://ant.apache.org/ 1.7+ (I used 1.7.1) and Git.
Then run “ant jar-complete” and copy jruby-complete.jar from the lib
directory under the checked-out jruby. Use the jruby-rack jar you want
also, for example “(jruby
version)/lib/ruby/gems/1.8/gems/warbler-0.9.13/lib/jruby-rack-0.9.4.jar”,
or you could check it out and built it as well if you wanted.

Note that you might want to blow away your tmp dir, existing war, as
well undeploy the webapp, etc. to clean up first.

Don’t forget that if you are using that version of jruby in the app,
you’ll want to use it in tests also. Make sure your JRUBY_HOME env var
is pointed to a symlink that is pointed to the jruby dir from git. And
make sure your PATH includes $JRUBY_HOME/bin.

Hi Nick!

The ‘$GEM_HOME/bin’ was in my path:

chris:~ mullerc$ echo $GEM_HOME
/opt/local/gem

chris:~ mullerc$ $PATH
-bash:
./:/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/opt/local/jruby/bin:/opt/local/gem/bin:/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin

Another option which hasn’t been mentioned yet is to try adding
$GEM_HOME/bin to your path, so that the binary scripts are there.

Hi Charlie!

This isn’t a package installation. I downloaded the binary distribution
of
jruby-1.3.0 and unpacked it. The only thing which is maybe not the
default
is, that I defined GEM_HOME in a directory which is not under the jruby
installation. The reason for that is, that I don’t want to install all
gems
again, if I upgrade jruby.
My JRUBY_HOME points to a directory, which is a link to the actual jruby
version I used:

chris:/opt/local mullerc$ ls -la

drwxr-xr-x 18 root admin 612 Jun 7 18:34 .
drwxr-xr-x 3 root wheel 102 Jun 5 18:18 …

Hmm, then it’s pretty peculiar that it installs in that other directory.
Can you confirm where installing a new gem with your new jruby-1.3.0
actually puts it?

I think your best bet may be to force things to a specific gem root/home
and reinstall what you had before.

Hi Charie!

After I definded a new GEM_HOME and installed all needed gems, it works.
Thank you! I don’t know, what goes wrong with my old GEM_HOME…
