Modified: src/scratchpad/schecoon/src/org/apache/cocoon/scheme/sitemap
SitemapManager.java
Log:
Added support for using the sitemap components. Pass the sitemap components object
as argument to the Scheme sitemap function instead of the ComponentManager. Setup the
environment properly so the Scheme sitemap could work.
