This is my hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping

        <property name=hibernate.dialect ">
            org.hibernate.dialect.MySQLDialect

            <property name=hibernate.connection.driver_class ">
                com.mysql.jdbc.Driver

                        jack

                        <property name=hibernate.connection.password ">
                            jack1234
                        </property-name>
                            <property name="show_sql">
                                true
                            </property>

                            <property name="connection.autocommit">
                                true
                            </property>
                            <!-- List of XML mapping files -->
                            <mapping resource="com/nousinfo/resource/Employee.hbm.xml" />
    </session-factory>
</hibernate-configuration>

This is my Employee.hbm.xml

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

Answer 1

You are getting this exception as

1. You haven’t put opening quotes (“) after name = in many lines in hibernate configuration file.
2. You have ended a property tag with property-name tag in multiple lines of hibernate configuration file.
3. Properties are not specified completely in hibernate configuration file.

Besides these, you hibernate configuration file is full of syntax errors. Refer the following link on how to prepare hibernate configuration file.
