Multiple EntityFactoryManager conflict - spring

Question

I have a grails application. I need to access to different database applications. I have added both as dependencies. I have created two different EntityManagerFactory for each database as you can see below. But I am getting this exception

Answer 1

Declare any of your entity factory as primary
<bean id="entityManagerFactory" primary="true" class='org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean'>
<property name="persistenceUnitName" value="persitanceUnit"/>
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.asklytics.dao" />
</bean>
