I am new to Hibernate. I have an exception while running an Hibernate-based application. The exception is as follows:

16 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.3.2.GA
16 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found
16 [main] INFO org.hibernate.cfg.Environment - Bytecode provider name : javassist

266 [main] ERROR org.hibernate.util.XMLHelper - Error parsing XML: XML InputStream(14) Attribute "coloumn" must be declared for element type "property".

It seems that it is not finding coloumn attribute of the property element in the mappings file but my mappings file do have the coloumn attribute.

Below is the mappings file (City.hbm.xml)

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

    <property name="cityDisplyaName" coloumn="CITY_DISPLAY_NAME" />
    <property coloumn="CITY_MEANINGFUL_NAME" name="cityMeaningFulName" />
    <property coloumn="CITY_URL" name="cityURL" />

  </class>

</hibernate-mapping>
