Application context duplicated

I have a Java SE application running a Jetty web server hosting a web application. I want to use Spring dependency injection both in the Jetty configuration and in the web application. Some beans, e.g. a dao and the entity manager, needs to be shared between the two. When I start the application I get duplicate versions of both the beans and the entity manager.

Spring prints this to the log:

Code:

---

WARN EntityManagerFactoryRegistry.addEntityManagerFactory:80 - HHH000436: Entity manager factory name (persistenceUnit) is already registered.  If entity manager will be clustered or passivated, specify a unique value for property 'hibernate.ejb.entitymanager_factory_name'

---

How can I make the web application use the same application context as the rest of the application and not duplicate all the beans?

I fix this issue just created two application context xml files:

1st. application-context.xml with entityManagerFactory bean. And registers in web.xml

Code:

---

<context-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>
                      /WEB-INF/application-context.xml
                </param-value>
</context-param>

---

2nd. application-context-web.xml without entityManagerFactory bean. And registers in web.xml

Code:

---

<servlet>
                <servlet-name>controller</servlet-name>
                <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
                <init-param>
                        <param-name>contextConfigLocation</param-name>
                        <param-value>
                                /WEB-INF/application-context-web.xml
                </param-value>
                </init-param>
                <load-on-startup>1</load-on-startup>
</servlet>
