Warbler 0.9.9 default servlet filter config doesn’t work with Websphere 6.1

Many people have been facing some issue when trying to deploy a JRuby on Rails package using Warbler on WebSphere AS 6.1.

One workaround is to copy the file JRUBY_HOME/lib/ruby/gems/1.8/gems/warbler-0.9.9/web.xml.erb to your app/config diretory and change it to use a Servlet instead of a Filter as below:


“-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN”

  <% webxml.context_params.each do |k,v| %>
      <param-name><%= k %></param-name>
      <param-value><%= v %></param-value>
  <% end %>

      <listener-class><%= webxml.servlet_context_listener %></listener-class>



  <% if webxml.jndi then webxml.jndi.each do |jndi| %>
      <res-ref-name><%= jndi %></res-ref-name>
  <% end; end %>

Also instead of changing the web.xml.erb file to use Servlet you can configure your WebSphere AS to work with Rack Filter. To do that you have to:

1. Start the Websphere server and open the Administration Console
2. Set a Websphere web container custom property = true.

If you have some difficult to find where to set this configuration tell me and I will give you the step-by-step.

I hope this tip be useful for everyone that is getting to work with JRuby On Rails on WebSphere.

All the best,
