Could you please help me on this.

Most probably you have a configuration problem.
Is Order entity mapped properly ? You are using it with the same name as the one in your mapping file ? Can you post your config file(s) ?

Hi,

This is a part of spring config file,

<bean id="datasource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost:3306/sample</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>admin</value>
</property>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSes sionFactoryBean">

<property name="mappingJarLocations">
<list>
<value>WEB-INF/lib/OrderManagerWeb.jar</value>
</list>
</property>
<!--<property name="mappingDirectoryLocations">
<list>
<value>classpath:com/tratum/ws/data</value>
</list>
</property>
--><property name="mappingResources">
<list>
<value>com/tratum/ws/data/Order.hbm.xml</value>
</list>
</property>

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
</props>
</property>

<property name="dataSource">
<ref bean="datasource" />
</property>

</bean>




and this is Order.hbm.xml

</hibernate-mapping>


Could you please check this.
Thanks for your reply,

What does OrderManagerWeb.jar file contains ?
If it contains Order.hbm.xml file I don't think you should specify it again (it should be loaded when the .jar file is inspected).
