Class DefaultDocumentLoader

java.lang.Object
  org.springframework.webflow.engine.model.builder.xml.DefaultDocumentLoader

All Implemented Interfaces:

DocumentLoader

public class DefaultDocumentLoader
extends java.lang.Object
implements DocumentLoader

The default document loader strategy for XSD-based XML documents with validation enabled by default.

Note: full XSD support requires JDK 5.0 or a capable parser such as Xerces 2.0. JDK 1.4 or < do not fully support XSD out of the box. To use this implementation on JDK 1.4 make sure Xerces is available in your classpath or disable XSD validation by setting the validating property to false.
