Adding gems to ScriptingContainer

Ruby JRuby
1

I’m still struggling with the task to embed a jruby setup into an
existing Java application. I tried rawr which doesn’t seem to do what I
wan’t. I played a bit more with the Scripting container and it works as
long as i reference the gems in my JRuby home. But I need to integrate
the gems into the jar I’m going to deploy.

Is this possible ?

My suggestion might be alternative to what in your mind.
If you don’t mind to use bundler, you can put all classes and gems in
a single jar easily. Here’s a gist gist:603328 · GitHub

I installed DataMapper gems in my Java project on Eclipse, so the path
to Gemfile includes user.dir system property. When you want to build
all in a jar archive, a path to Gemfile should be something like
“jar:…”

Hope this helps.

Since bundle doesn’t support any kind of jar packaging it seems that I
have to package the gem directory created by bundler into a jar
archive. Right?

This approach looks really promising. My problem was that I I thought
the requiring a jar will only work for jars containing class files.

I tried jar packaging,

Perhaps, this is one of the packaging measures of Java code and gems.
