[Jruby-extras-devel] Pleasantly surprised at rails-integration

[Fausto Lelli]

Hi,

I did tested getting a war in standalone mode (that means with all of
jruby packaged
up in the WEB-INF lib directory, but please referer to preceding discussion to
the thread RoR in War ) ad worked for me

1) install plugin:
script/plugin install
svn://rubyforge.org/var/svn/jruby-extras/trunk/rails-integration/plugins/create_war
2) rake war:standalone:create
3) I had to manually add jvyaml.jar to the generated  WEB-INF/lib
directory but I
don't know if it is a problem with my config or else it has since been fixed.

As for the implementation, I think it is as you described before,
maybe Robert can
confirm for sure.

One thing that worries me a little bit now is multiple rails runtime
instances (pooled),
which slows startup a lot. But since this is all meant for production
deployment, this could be a no-problem.

Cheers,
Fausto.
