I am fairly new to Ruby as well as Processing, but I have a page built in Ruby and would like to know how to display my Processing .PDE files on that Page. I have read online that you need Processing.js
i have copied the code for processing.js from [processingjs.org][1] and put it in a file called processing.js in app/assets/javascripts
I have saved a .pde file called butters.pde in app/assets/images/data.
Am I calling the script correctly in the header and the file correctly in the body? I'm not seeing anything when I try to view the page.
<head>
<title>Hello</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>

<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="assets/javascripts/processing.js"></script>
</head>
and
<body>
<canvas data-processing-sources="/assets/images/data/butters.pde"></canvas>
</body>
The Terminal reads:

Hi i upgraded my struts project from 2.3.20 to 2.5.2 and when i am trying to run, it is throwing me exception in JsonInterceptor. I am unable to figure out why it throwing this exception after upgrading struts to 2.5.2. I have also change my struts.xml file according to it. But still it is showing me same error. Can anyone help me what i am missing.

I have already specified gem 'mysql2', '~> 0.3.18' in my Gemfile on so I don't know what other solution that I could use to fix this.
Please help. Thanks! :)
I finally solved it.
Actually, after added gem 'mysql2', '~> 0.3.18' , I need to push it to my repository on Github first before deploying it to the server.
I have a model class "Abtest" that inherits from an abstract base class "ModBase" which does not have a backing table. When Abtest.new is called, I got the following error even though in ModBase class I have "self.abstract_class = true". What did I do wrong?
class ModBase < ActiveRecord::Base
self.abstract_class = true
class Abtest < ModBase

It's a Rails bug in 3.1.0.
https://github.com/rails/rails/issues/558
I have upgraded to 3.1.11 and the error never happened again.
You haven't run your migrations. Which is what this error is all about. ActiveRecord will need a table for ModBase regardless of STI. All STI does is set the "type" column.
Since it sounds like you're trying to do a table less setup... What you might be looking for is probably found in ActiveModel. Essentially you get a lot of the AR goodness without the database requirement.
Railscast on ActiveModel
Has anyone managed to get Rails 3.2 working on Solaris-10 with JRuby?
We appear to be caught in a nasty dependency vortex. Rails 3.2 requires JRuby 1.6.6 or later, according to: Using JRuby with Rails 3.2
But JRuby 1.6.5 is the last version that can successfully install gems on Solaris: http://jira.codehaus.org/browse/JRUBY-6494
Is it possible that there is a patch out there or something we haven't thought of?
We have a Rails 3.2.2 app working on Solaris. We're using JRuby 1.6.5.1 and the latest warbler, but we had to downgrade jruby-rack to 1.1.5 I believe.
What doesn't work is asset compilation, because we haven't found a working javascript runtime. Node.js doesn't support Solaris Sparc, and therubyracer had compilation issues we didn't spend too much time trying to resolve. So we currently precompile assets on local development workstations (Windows). We're not really using the asset pipeline (and I'm not convinced it was a good idea to make it the Rails default), so we may disable it so that we can run a CI build on Solaris.

I'm hopeful that the JRuby team will spend some time making JRuby 1.7 work on Solaris. Otherwise we'll have to accelerate our migration to linux...
