Question

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
31 [main] INFO org.hibernate.cfg.Environment - using JDK 1.4 java.sql.Timestamp     handling
94 [main] INFO org.hibernate.cfg.Configuration - configuring from resource: /hibernate.cfg.xml
94 [main] INFO org.hibernate.cfg.Configuration - Configuration resource: /hibernate.cfg.xml
219 [main] INFO org.hibernate.cfg.Configuration - Reading mappings from resource : app/data/City.hbm.xml
266 [main] ERROR org.hibernate.util.XMLHelper - Error parsing XML: XML InputStream(12) Attribute "coloumn" must be declared for element type "property".
266 [main] ERROR org.hibernate.util.XMLHelper - Error parsing XML: XML InputStream(13) Attribute "coloumn" must be declared for element type "property".
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"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="app.data">

  <class name="City" table="CITY">

    <id column="CITY_ID" name="cityId">
      <generator class="native"/>
    </id>

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

  </class>

</hibernate-mapping>

You mean column. It’s complaining because coloumn is not a valid attribute of <property>
