Rosette Entity Resolver - Basis Technology.
When Forrest processes the documents, it uses the Resolver to find Forrest's local copies of the DTDs, rather than trundling out onto the network. Many Java-based XML tools already have an entity resolver, probably the same one that Forrest uses. Many non-Java tools also have an entity resolver.
The task of such an entity resolver is to point the XML parser to the location of the file referred to by the declaration. So in our example the entity resolver would load the DTD file from a local cache instead of retrieving it from the internet.
The Javax.xml.parsers.DocumentBuilder.setEntityResolver(EntityResolver er) method specifies the EntityResolver to be used to resolve entities present in the XML document to be parsed. Setting this to null will result in the underlying implementation using it's own default implementation and behavior.
This defines a resolver that always returns a dynamically generated DTD fragment defining an entity. The url argument passes the system URL of the requested document, the id argument is the public ID. Note that any of these may be None. The context object is not normally used by client code.
Rather than writing an entity resolver function yourself, CXML can use XML catalogs to find DTDs and entity files on your local system. Catalogs are particularly helpful for DTDs that are pre-installed. For example, most Linux distributions include a package for the XHTML DTD.

We will make the tutorial with the same example of the Brochure field and Product entity in the official article of Symfony. 1. Configure FormType with FileType. The first thing you need to do, is to define the field of the form that should be used to upload the file using the FileType.
