Question

import com.sun.org.apache.xerces.internal.dom.DOMImplementationImpl;
public static Document newDocument( String pName ) {

    return DOMImplementationImpl.getDOMImplementation().createDocument(
        null,
        pName,
        DOMImplementationImpl.getDOMImplementation().createDocumentType( pName, null, null ) );

}

I have encounter with below warnings in netbeans

warning: com.sun.org.apache.xerces.internal.dom.DOMImplementationImpl is Sun proprietary API and may be removed in a future release
return DOMImplementationImpl.getDOMImplementation().createDocument(

Don’t refer to a concrete DOMImplementation. Instead, use:

DOMImplementationRegistry registry = DOMImplementationRegistry.newInstance();
DOMImplementation implementation = registry.getDOMImplementation("XML 1.0");
DocumentType type = implementation.createDocumentType(pName, null, null);
Document document = implementation.createDocument(null, pname, type);    

Alternatively, use a rather less factory-heavy XML API, like JDOM 🙂 (I’ve always found the Java W3C DOM API to be a complete pain to work with.)

Yet another alternative would be to use a concrete DOMImplementation, but make it an external one rather than relying on an implementation built into the JDK. This could still be Apache Xerces, just from a jar file.
