Thanks James for your insight into the implementation.
Let me tell you the scenario. My source code
System.setProperty(DOMImplementationRegistry.PROPERTY,
"org.apache.xerces.dom.DocumentImpl");
DOMImplementationRegistry registry =
DOMImplementationRegistry.newInstance();
DOMImplementationLS impl =
(DOMImplementationLS)registry.getDOMImplementation("LS");
LSParser builder = impl.createLSParser(
DOMImplementationLS.MODE_SYNCHRONOUS, null);
org.apache.xerces.dom.DeferredDocumentImpl document =
(org.apache.xerces.dom.DeferredDocumentImpl)builder.parseURI("personal.xml");
The above line of code gives me ClassCastException.
org.apache.xerces.dom.DeferredDocumentImpl extends
org.apache.xerces.dom.DocumentImpl so I tried to cast it to
org.apache.xerces.dom.DocumentImpl. The above code uses JDK1.5.
Is there any otherway to achieve the same with JDK1.4.2?
regards,
Ranjan
