In hibernate configuration file you missed out the mapping element for your hbm file.you should define like in your hibernate.cfg.xml..

I think that you have to add a mapping for your Tbluser.hbm.xml in your hibernate cfg

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

    <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
    <hibernate-configuration>
      <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernate</property>
        <property name="hibernate.connection.username">root</property>

  <!-- List of XML mapping files -->
   <mapping resource="Tbluser.hbm.xml"/>
      </session-factory>
    </hibernate-configuration>

It sounds like the xml parser is trying to access the schema or dtd mentioned in the configuration file and fails to succeed.

Make sure your application has access to http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd or get the document from there put it somewhere where your application can access it add change the path in the document accordingly
