I'm trying to access a Spring bean in an EJB3 but it doesn't seem to get injected because I'm getting a NullPointerException.
I think I'm not understanding the role of beanRefContext.xml and how it's used very well.
The following EJB and XMLs are in a services JAR that resides in the WEB-INF/lib of a WAR. The Spring bean (the DAO) is in a separate JAR also in WEB-INF/lib.
EJB:
@Stateless
@Interceptors(SpringBeanAutowiringInterceptor.class)
public class TimetrackingServiceBean implements TimetrackingService {
@Autowired
private UserDao userDao;
@Override
public List<User> getAllUsers() {
return this.userDao.findAll(); // <-- NPE
}
}
beanRefContext.xml:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
<bean name="serviceContext" class="org.springframework.context.support.ClassPathXmlApplicationContext"></bean>
</beans>
services-context.xml:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<context:annotation-config />
</beans>
EDIT
I read the post "Inject Spring beans into EJB3" and now I added a context-param to web.xml but the problem remains.
web.xml:
...
<context-param>
<param-name>parentContextKey</param-name>
<param-value>serviceContext</param-value>
</context-param>
...
I apparently need more help and explanation.
