Use OpenEntityManagerInViewFilter in my project? - spring

Question

due to Lazy loading problems with hibernate I try to set up springs OpenEntityManagerInViewFilter.
But I cannot get it to work with my already working app.
What else appart from adding things to web.xml and creating a applicationContext.xml to I have to do, in order to use the Open EM?
Thanks
I have added to web.xml:
<filter>
<filter-name>
OpenEntityManagerInViewFilter
</filter-name>
<filter-class>
org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter
</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>flushMode</param-name>
<param-value>AUTO</param-value>
</init-param>
</filter>
<!-- Include this if you are using Hibernate -->
<filter-mapping>
<filter-name>OpenEntityManagerInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring config -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
and an applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd">
</beans>
I already can deploy my app, but when I try to launch it throws ex:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' is defined

Answer 1

Create an entityManagerFactory into your applicationContext.xml like this:
<!-- Add JPA support -->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
</bean>
<!-- Add Transaction support -->
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

Answer 2

As the error suggests you do not have a entityManagerFactory defined in your spring config files. Or it is defined with some other name. Try adding this init param to the config in web.xml
<init-param>
<param-name>entityManagerFactoryBeanName</param-name>
<param-value>entityManagerFactory</param-value>
</init-param>
