This document offers a brief summary of what has changed in the Apache XML Commons Resolver package since the 1.0 release.
The most pervasive change is that the CatalogManager
class is no longer static. It's now possible to instantiate several catalog
managers and each manager can manage several catalogs.
There is still a single static instance of the
CatalogManager, available via
getStaticManager(). This is used by default
if no other catalog manager is instantiated and used. It behaves as
the old static one used to.
In the previous version, the system catalogs were not loaded if a private catalog was requested. That has changed; the system catalogs are now always loaded.
If you want to avoid loading any system catalogs, establish your own
CatalogManager and use the
setCatalogsFiles() method to assure that no system
catalogs are available.
There are several tests in the tests/resolver directory
that demonstrate how different instantiations can be used.
The resolver now includes catalog.{dtd,rng,xsd} and uses a "bootstrap" resolver when it is loading catalog files. This avoids the Catch-22 of having to resolve this before the resolver is in action ...
