Facing org.xml.sax.SAXParseException

Question

Here is the web.xml file

<?xml version="1.0" encoding="UTF-8"?>

This is the error I am facing:

Answer 1

Your (basic XML) parsing error comes from the fact that two root tags ( <web-app> and <hibernate-configuration> ) have been found in your document.

It looks like you have simply gathered the content of two XML configuration files, but it doesn't work like this. As stated in a comment, webapp configuration must be set in web.xml, and Hibernate is usually set in hibernate.cfg.xml.

Answer 2

Whenever you face an org.xml.sax.SAXParseException type of Exception it is better start with validating your xml. This site comes in handy when you want to validate xml files either by uploading or just pasting the text.
