Example:

ObjectFactory factory = new ObjectFactory();

Unmarshaller u = factory.createUnmarshaller();

Cars cars = (Cars) u.unmarshal(new FileInputStream(“cars.xml”));

unmarshal method ACCEPTS:

• java.io.File
• java.io.InputStream
• java.net.URL
• javax.xml.transform.Source

related to XSLT:

org.w3c.dom.Node

related to DOM:

org.xml.sax.InputSource

related to SAX:

• Other Unmarshaller methods
 void setValidating(boolean validating)
• true to enable validation during unmarshalling; false to disable (the default)
boolean setEventHandler(ValidationEventHandler handler)
• handleEvent method of ValidationEventHandler is called
if validation ERRORS are ENCOUNTERED during unmarshalling
• default handler terminates marshalling after first error
• return true to continue unmarshalling
• return false to terminate with UnmarshalExceptio
• SEE discussion of ValidationEventCollector later
