Question

I have simple application with following folder structure:

• ProjFolder
• |—–src
• |———-packagename
• |—————{sourcefiles}
• |———-META-INF
• |—————{beans.xml}
• |—————{hibernate.cfg.xml}
• |—————{EntityMapping.hbm.xml}

here is the part of beans.xml Spring config file:

<bean id="propertyConfigurer"  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="classpath:./META-INF/jdbc.properties" />
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="${jdbc.driverClassName}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:./META-INF/hibernate.cfg.xml" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
        </props>
    </property>

    <property name="mappingResources">
<list>
      <value>classpath:./META-INF/EntityMapping.hbm.xml</value>
</list>
 </property>
</bean>

<tx:annotation-driven transaction-manager="txManager" />

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

when i start my unit tests i getting following exception:

org.springframework.beans.factory.BeanCreationException: Error
creating bean with name ‘wrapperClass’ defined in class path resource
[META-INF/beans.xml]: Cannot resolve reference to bean ‘wrapperClassField’
while setting constructor argument; nested exception is
org.springframework.beans.factory.BeanCreationException: Error
creating bean with name ‘xmlBooksource’ defined in class path resource
[META-INF/beans.xml]: Cannot resolve reference to bean
‘sessionFactory’ while setting bean property ‘sessionFactory’; nested
exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name ‘sessionFactory’ defined in class path
resource [META-INF/beans.xml]: Invocation of init method failed;
nested exception is java.io.FileNotFoundException: class path resource
[classpath:/META-INF/EntityMapping.hbm.xml] cannot be opened because it does not exist

The same exception is thrown when i type

<property name="mappingResources">
<list>
      <value>EntityMapping.hbm.xml</value>
</list>
 </property>

Why spring cant find this file and how i must fill its location to make this code work?

Thanks in advance.

Have you tried removing the classpath: prefix? In looking at the Hibernate code, the mappingResources setter expects passes the strings to new ClassPathResource(String). This expects classpath resources already. The string then gets passed to ClassLoader.getResourceAsStream(String). None of this code would strip the “classpath:” prefix from the front of the resource string.
