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);

Multitenancy

What is Multitenancy? Multitenancy is an architecture in which a single instance of a software application serves multiple customers. It gives the ability to use the same software and interfaces to configure resources and it isolates customer-specific traffic and data. Each customer is called a tenant. Tenants may be given the ability to configure some parts of the application, such as color of the user interface ( UI ) or business rules , but they cannot change the application's code . This means that although tenants are using the same building blocks in their configuration, the appearance or workflow of the application may be different for two tenants. Also, the Service Level Agreement (SLA) of each tenant can differ [1]. Multitenancy vs. Singletenancy: Multitenancy can be economical because software development and maintenance costs are shared. It can be contrasted with single-tenancy, an architecture in which each customer has their own software instance and ...
