And the mapping xml file is

<?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>
<class name="jdbc.Item" table="item">

<id name="It_id" column="idItem" type="integer">

</id>
</class>
</hibernate-mapping>

Please help me.......

You probably need to quote some of your table and/or column names. See http://docs.jboss.org/hibernate/core/3. ... dentifiers for more information. From the small SQL fragment in the stack trace it seems like you have a table named 'order' which is a keyword in SQL.
