Hello,
I have an application that works fine when I have JSF in control of my
managed beans. Now I try to replace this with CDI. I replaced (nearly)
all the @EJB annotations with @Inject. For the managed beans I added
@Named and @SessionScoped (or another scope). The application works fine
until I want to access the managed beans through:
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get(<bean
name>)
Seems logic to me since I do not want to use JSF for that anymore. I
searched and found that you can access them through the BeanManager. I
get the BeanManager like this:
(BeanManager) initialContext.lookup("java:comp/BeanManager")
When I do a getBeans(<bean name>) then I get a bean with
beans.iterator().next() and this is the bean I need. I do a
bean.getBeanClass().getName() and the name is correct. When I cast the
bean to its class then I get a java.lang.ClassCastException:
org.apache.webbeans.component.ManagedBean cannot be cast to
What is my mistake?
I use tomee 1.5.1. My application is packaged as WAR. I added an empty
beans.xml into the WEB-INF and in the JAR files in the META-INF where I
have the Managed Beans. My faces-config.xml only has a phase-listener
defined. I do not know if I still need the phase-listener.
public static BeanManager getBeanManager() {
BeanManager beanManager = null;
try {
final InitialContext initialContext = new InitialContext();
beanManager =
(BeanManager) initialContext.lookup("java:comp/BeanManager");
System.out.println("Gevonden.");
} catch(NamingException e) {
LOGGER.error("BeanManager not found.", e);
}
return beanManager;
}
public static Bean<?> getBean(String beanname) {
Set<Bean<?>> beans = getBeanManager().getBeans(beanname);
if (beans.isEmpty()) {
LOGGER.debug("Bean " + beannaam + " not found.");
return null;
}
Bean<?> bean = beans.iterator().next();
// System.out.println("Bean: " + bean.getBeanClass().getName() + " ("
+ beans.size() + ")");
return bean;
}
