Asciidoctor Servlet demo

mojavelinux
Administrator
In preparation for my JUG talks this week on AsciiDoc/Asciidoctor and Arquillian, I created a simple demo webapp that accepts AsciiDoc source and renders it using the Asciidoctor Java integration library.

I included Arquillian tests in the project that test the CDI bean, the web UI (using Drone) and the Servlet lifecycle (using Warp). The project is also configured to use the Asciidoctor Maven plugin.

The application only works on GlassFish atm. For some reason, the Asciidoctor Java integration can't resolve RubyGems when deployed to Wildfly (JBoss AS). But, hey! There are Arquillian tests ready to go to explore the problem :)


Happy hacking!

Some news about deploy in jboss7?

I tried with latest asciidoctor-java-integration, but the error is always the same:

Caused by: org.jruby.exceptions.RaiseException: (LoadError) no such file to load -- asciidoctor
        at org.jruby.RubyKernel.require(org/jruby/RubyKernel.java:1054) [jruby-complete-1.7.4.jar:]
        at RUBY.require(classpath:/META-INF/jruby.home/lib/ruby/shared/rubygems/custom_require.rb:36) at RUBY.(root)(<script>:2)


bye

I have not tried yet but you could try what have been explained here https://github.com/asciidoctor/asciidoctor-java-integration/issues/22 with OSGi, but it can also works in JBoss

Re: Asciidoctor Servlet demo

I plan to deploy my asciidoc application to openshift so I've also hit the problem with jboss classloading and jruby. I've read the discussion and play with gem_path a bit but I don't yet know what to do. What I understand is that it is the problem with how jruby loads gem libraries putted inside jar files and without changes from their side there won't be any final solution. What we can have now is some workaround with unpacking content of asciidocotor-java-integratation jar and setting gem_path correctly.

Any recommendation how can I tackle that problem?

Btw maybe it will be good to have this information in asciidoctor-java-integration readme file so people planning to use it with jboss server won't be surprised at the moment of deploying it?

I'd have to experiment with it myself before I could give advice for how to make it work with JBoss AS. You might want to reach out to the Wildfly or Torquebox list to get advice since both groups should have the necessary expertise.

I can offer another approach. I know that this runs on GlassFish. You could start with the GlassFish OpenShift quickstart and then add the servlet demo to it.

I think that's a great suggestion. Let's capture that knowledge. Anything you learn, please post it here or submit a pull request to the asciidoctor-java-integration README.md.

Good luck!

Your application after small modification also works on tomcat so I will go for it.  I wish I can say the same about my app, but at least I know that it can be done somehow.

As of Jboss I have to postpone my investigation as I have really few spare time now.

I've already solved my problems also. Everything is working on standalone Tomcat and Tomcat on Origin so I am quite satisfied. Now is time to complete business logic and polish the code. After that I would love to contribute also to asciidoctor-java-integration module.

Hi,

I have the same problem on OpenShift with WildFly 8.0.0-beta1[2] but it's not a problem about the application server since it works on my laptop.

My project use the WebSocket protocol to render HTML in live mode [1] and I would like to put a demo online.

Any idea ?
It may be a platform security problem ?

I've just checked it locally with WildFly and it doesn't work. The error is the same. 

Caused by: org.jruby.exceptions.RaiseException: (LoadError) no such file to load -- asciidoctor
at org.jruby.RubyKernel.require(org/jruby/RubyKernel.java:1027) [jruby-complete-1.7.3.jar:]
at RUBY.require(classpath:/META-INF/jruby.home/lib/ruby/shared/rubygems/custom_require.rb:36) at RUBY.(root)(<script>:2)

It may so happen that you have GEM_PATH set locally and thats why it is working. As I dig throughout the problem, it is modular classloader that cause JRuby can't find gem files on the classpath. I try to find a bug in JRuby but nothing exactly the same was reported yet. 

I don't know how but TorqueBox seems to overcome that issue somehow. Maybe we can check with them?
