An attempt was made to insert a node where it is not permitted

Do you face this Error while you are writing code to generate xml file from java?


Exception in thread "main" org.w3c.dom.DOMException: HIERARCHY_REQUEST_ERR: An attempt was made to insert a node where it is not permitted.
       at com.sun.org.apache.xerces.internal.dom.CoreDocumentImpl.insertBefore(Unknown Source)
       at com.sun.org.apache.xerces.internal.dom.NodeImpl.appendChild(Unknown Source)
       at generatexml.WriteXMLFile.main(WriteXMLFile.java:30)

Well the answer is:
  1. Don't insert the node where it isn't permitted.
  2. Change your generated directory file path from 'C' to other directory ex, D or to any directory you have.
  3. Make sure the ‘appendChild’ is referring to the right element.
  4. Don’t appending twice, only make it once. Ex,
//Writetoxml.java
  Element rootElement = doc.createElement("Company"); 
   doc.appendChild(rootElement);             
  Element subElement = doc.createElement("Department");     
   doc.appendChild(myElement);
