A component that uses catalogs for resolving Entities. This implementation uses the XML Entity and URI Resolvers from http://www.sun.com/xml/developers/resolver/ published by Sun's Norman Walsh. More information on the catalogs can be found at http://xml.apache.org/cocoon2/catalog.html The catalog is by default loaded from "/resources/entities/catalog". This can be configured by the "catalog" parameter in the cocoon.xconf: <resolver> <parameter name="catalog" value="mycatalog"/> </resolver>

The Parser will call this method before opening any external entity except the top-level document entity (including the external DTD subset, external entities referenced within the DTD, and external entities referenced within the document element): the application may request that the parser resolve the entity itself, that it use an alternative URI, or that it use an entirely different input source.
Application writers can use this method to redirect external system identifiers to secure and/or local URIs, to look up public identifiers in a catalogue, or to read an entity from a database or other input source (including, for example, a dialog box).
If the system identifier is a URL, the SAX parser must resolve it fully before reporting it to the application.
