I have no websphere experience, but I can suggest a couple of things to try:
- If you want to still use the filter, try playing around with the
filter prefix in web.xml. (Maybe try '/' instead of '/*' and so on.)
- You can also try the servlet version, which would use config like
this in web.xml. Comment out or remove the filter/filter-mapping bits
and use this instead:
<servlet>
<servlet-name>RackServlet</servlet-name>
<servlet-class>org.jruby.rack.RackServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>RackServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
