I am getting this error when integrating Hibernate with Spring

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is org.hibernate.MappingException: invalid mapping


This is my applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">



<beans>

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName"><value>com.mysql.jdbc.Driver</value></property>
<property name="url"><value>jdbc:mysql://localhost:3306/rml</value></property>
<property name="username"><value>mm</value></property>
<property name="password"><value>mm</value></property>

</bean>

<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource"><ref bean="myDataSource"/></property>
<property name="mappingResources">
<list>
<value>/com/rml/user.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQLDialect
</value>
</property>
</bean>

<bean id="userdao" class="com.rml.UserDAO">
<property name="sessionFactory"><ref bean="mySessionFactory"/></property>

</bean>

</beans>


In the Spring I used as

<bean id="userController" class="com.rml.UserController">
<property name="userdao"><ref bean="userdao"/></property>

</bean>


Please help me How to solve this error

mahest2001,

Your problem seems to be in the mapping file (or whatever you are using for mapping classes to tables), not in the application.xml

I used one mapping file user.hbm.xml is

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="com.rml.UserBean" table="User">


<property name="firstName" column="first_name"/>
<property name="lastName" column="last_name"/>
<property name="password" column="password"/>



</class>

</hibernate-mapping>


I have created user table in mysql

Please help it

Your mapping lacks an id, which is mandatory.

Thanks for your help. It is working now
