### (Other) Rack Applications

8789
The main difference when using a non-Rails Rack application is that JRuby-Rack
8890
looks for a "rackup" file named **config.ru** in `WEB-INF/config.ru` or
8991
`WEB-INF/*/config.ru`. Here's a sample *web.xml* configuration :

If you don't have a *config.ru* or don't want to include it in your web app, you
106110
can embed it directly in the *web.xml* as follows (using Sinatra as an example):
