I do not recall correctly why, but there are some issues with standard
URLStreamHandlers, that's why Cocoon have own set of classes to handle
protocols. If you wish to have better integration with Cocoon (including
better integration with caching sub system), consider writing your news
protocol implementing using org.apache.cocoon.environment.Source. Look
into org.apache.cocoon.components.source package for the examples.
All Cocoon protocols are declared in cocoon.xconf file:
------8<-------------------------------------------------
<!-- URL Factory:
The url factory adds special url protocols to the system, they are
then
available inside Cocoon, e.g. as a source argument for one of the
sitemap
components.
-->
<url-factory logger="core.url-factory">
<!-- Allows access to resources available from the ClassLoader,
using getResource() method. -->
<protocol name="resource"
class="org.apache.cocoon.components.url.ResourceURLFactory"/>
<!-- Allows access to resources available from the servlet context,
using getResource() method. -->
<protocol name="context"
class="org.apache.cocoon.components.url.ContextURLFactory"/>
<!-- Add here protocol factories for your own protocols -->
</url-factory>
