Property 'entityManagerFactory' is required

Question

I just started to develop an application that's meant to support an already existing web project, therefore the business and persistence layers already exist and are working very well within that web application. Now as I use the libs for both layers in my console application I get an error that the JpaTransactionManager requires the entityManagerFactory, which is weird, because it doesn't throw an exception in my web app. All I do in my console application is creating the application context

public static void main(String[] args) {
    ApplicationContext ctx = new ClassPathXmlApplicationContext("engine-context.xml");

}

the engine-context.xml:

<import resource="business-context.xml" />
<import resource="persistence-context.xml" />

<tx:annotation-driven transaction-manager="myTxManager" proxy-target-class="true"/>

Stacktrace:

All I do in my web application is to define the context XML files in the web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/applicationContext.xml
        classpath:persistence-context.xml   
        classpath:business-context.xml          
    </param-value>
</context-param>

there's no more magic in the applicationContext.xml

<!-- SESSION: -->
    <bean name="spielerSession" class="org.boogerrangers.persistence.dom.SpielerLogin" scope="session"  >
        <aop:scoped-proxy/>
    </bean>

<!-- FILTER: -->
    <bean name="authFilter" class="org.boogerrangers.game.filter.AuthFilter" >
    </bean>

... DAOs ...

more information needed?

as a dirty workaround I created a new persistence-context and use this instead but that's confusing and I don't wanna have redundant configurations. I also created a second webapp doing the same thing as in the standalone app with no thrown exceptions.

thanks in advance.

Answer 1

It seems the data source is injected in the transaction manager

<bean id="myTxManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

But in our case, you need to use the entity manager instead of the data source, as you use JPA transaction manager:

<bean id="myTxManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean> 

Answer 2

JpaTransactionManager should be supplied with EntityManagerFactory:

<bean id="myTxManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean> 

Its dataSource property is optional, it's only needed if you are going to mix JPA with plain JDBC access.
