There are 2 mistakes with this line

<mapping calss="com.jlcindia.hibernate/Customer"/>

  1. class is mis-spelled as calss.

  2. com.jlcindia.hibernate/Customer should have been com.jlcindia.hibernate.Customer - I'm assuming that this is the entity class.

After correcting the 2 mistakes, that line should something like this

<mapping class="com.jlcindia.hibernate.Customer" />

Side Note: A good IDE would have highlighted the error in the xml file then and there(with where exactly the error is). I suggest you use one(in case you're not using any).

The stacktrace is stating that the doctype header is missing - add the line

<!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >

at the start of the XML configuration file

There is an additional / which is terminating the tag early also a "class" typo both in the mapping tag . Replace

<mapping calss="com.jlcindia.hibernate/Customer"/>

with

<mapping class="com.jlcindia.hibernate.Customer"/>
