For a non-Java solution, you could use the random number input module (http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/components/modules/input/RandomNumberModule.html) and pass the number to an XSLT which operates on the sitetree. You can use the modulo operator with the number of existing nodes in the sitetree to select the document. This approach will be terribly slow compared to a Java-based solution as suggested by Thorsten. Anyway, I'd recommend an input module instead of an action (less code in the sitemap). -- Andreas > > This way the features described by solprovider should be easy to > implement with a nice java component. > > salu2 > >> Some interesting ideas here! >> >> It doesn't have to be strictly "Page of the day" ("Page of the browser >> refresh" is fine for our purposes).
