I have isolated the cause of the Bug. It looks like it will
be easy to fix :-) though it will need someone else to do it.
As described in Bugzilla - here is a summary ...
Everything works fine with the entity resolver when Cocoon
is running as a webapp.
However, when running as commandline context while doing
"build docs" the entity resolver delivers strange system Identifiers
(problem with file://) and then the subsequent messages "Failed
to create InputSource". (To make it more complex, this only
happens on UNIX-based platforms.)
Below i have extracted snippets from two log files. The first is
from "build docs". The second is from running Cocoon as a
webapp under Tomcat. Note the last line of each snippet.
This is where the filesystem path for the catalog is constructed
in components/resolver/ResolverImpl.java and then the catalog
is loaded by the entity resolver. Note that in the build docs case,
there is a relative pathname and in the webapp case there is a
full pathname.
Apparently the entity resolver does not like loading catalogs
using a relative pathname. This can be proven by hacking
ResolverImpl.java (around line #98) and using a hard-coded
path to the catalog. The entity resolver loads its catalog properly
and build docs proceeds properly.
So it seems that there is inconsistency when using getResource()
...
String catalogFile = params.getParameter("catalog",
"/resources/entities/catalog");
String catalogURL = this.context.getResource(catalogFile).toExternalForm();
There must be a reliable way to get the full filesystem
pathname in both situations, but i cannot see how.
