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:
<!DOCTYPE web-app PUBLIC
“-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN”
"http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <% webxml.context_params.each do |k,v| %> <context-param> <param-name><%= k %></param-name> <param-value><%= v %></param-value> </context-param> <% end %> <listener> <listener-class><%= webxml.servlet_context_listener %></listener-class> </listener> <servlet> <servlet-name>Rails</servlet-name> <servlet-class>org.jruby.rack.RackServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Rails</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <% if webxml.jndi then webxml.jndi.each do |jndi| %> <resource-ref> <res-ref-name><%= jndi %></res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> <% end; end %> </web-app>
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 com.ibm.ws.webcontainer.invokefilterscompatibility = 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,
