Adding New Child node to a Document

[Pranjal Bhatnagar]

In order to add a new Child node to a Document-doc, I try the following code.   doc.adoptNode(childNode); doc.appendChild(childNode);   However this gives a ClassCastException as follows while executing doc.adoptNode();   Exception in thread "main" java.lang.ClassCastException: org.apache.xerces.dom.D ocumentImpl         at org.apache.xerces.dom.DeferredAttrNSImpl.synchronizeChildren(Deferred AttrNSImpl.java:182)         at org.apache.xerces.dom.AttrImpl.setOwnerDocument(AttrImpl.java:214)         at org.apache.xerces.dom.NamedNodeMapImpl.setOwnerDocument(NamedNodeMapI mpl.java:421)         at org.apache.xerces.dom.ElementImpl.setOwnerDocument(ElementImpl.java:1 93)         at org.apache.xerces.dom.ParentNode.setOwnerDocument(ParentNode.java:226 )         at org.apache.xerces.dom.ElementImpl.setOwnerDocument(ElementImpl.java:1 91)         at org.apache.xerces.dom.CoreDocumentImpl.adoptNode(CoreDocumentImpl.jav a:1181)         at Test.parse(Test.java:49)         at Test.main(Test.java:11)     In case I use doc.importNode(childNode, true) a NullPointerException is thrown while trying to retrieve the Doc elements.   Is this approach correct or do we need to do something else?   Thanks, Pranjal
