Websphere V8.5 get BeanManager over JNDI

Question

I have a custom ConstraintValidatorFactory which shall get a BeanManager over JNDI. I use a custom factory to inject ressources in my validator classes.

The application getting deployed on a Websphere V8.5.

But when i use my validator the injected values return always null.

This works like a charm with JBoss.

My thought is that WebSphere has another JNDI ID for the Ressource.

    private static BeanManager beanManager;

    @SuppressWarnings("unchecked")
    @Override
    public <T extends ConstraintValidator<?, ?>> T getInstance(Class<T> clazz) {
        // lazily initialize the beanManager
        if (beanManager == null) {
            try {
                InitialContext ctx = new InitialContext();
                beanManager = (BeanManager) InitialContext
                        .doLookup("java:comp/env/BeanManager");
            } catch (NamingException e) {
                throw new RuntimeException(e);
            }
        }

        T result = null;

        Bean<T> bean = (Bean<T>) beanManager.resolve(beanManager
                .getBeans(clazz));
        if (bean != null) {
            CreationalContext<T> context = beanManager
                    .createCreationalContext(bean);
            if (context != null) {
                result = (T) beanManager.getReference(bean, clazz, context);
            }
        } else {
            try {
                result = clazz.newInstance();
            } catch (Throwable t) {
                throw new RuntimeException(t);
            }
        }

        return result;
    }

    @Override
    public void releaseInstance(ConstraintValidator<?, ?> instance) {
    }

}

* UPDATE *

I tried to inject the BeanManager in my controller with @Resource and get following stacktrace:

* UPDATE **

After i tried a lot of things i create the ValidatorFactory by hand as described here

@Inject BeanManager beanManager;

...

    ValidatorFactory validatorFactory = Validation.byDefaultProvider()
            .configure()
            .constraintValidatorFactory(new CDIConstraintValidatorFactory(beanManager))
            .buildValidatorFactory();
    Validator validator = validatorFactory.getValidator();

Inside an EJB I can get the BeanManager over regular @Inject and put it in the constructor of my Custom ConstraintValidatorFactory.

Answer 1

It works both ways using injection and JNDI. Your JNDI name was incorrect. It is java:comp/BeanManager as documentation says - BeanManager javadoc

Injecting via @Resource like this:

@Resource
BeanManager bmanager;

Using JNDI:

   InitialContext ctx;
   try {
        ctx = new InitialContext();
        BeanManager bm2 = (BeanManager) ctx.lookup("java:comp/BeanManager");
        System.out.println("bm2: " + bm2);
    } catch (Exception e) {
        e.printStackTrace();
    }

Remember that you need to have beans.xml file in the WEB-INF folder to enable CDI.

UPDATE
If it initializes correctly you should see following messages in the log:

[8/15/14 12:41:40:493 CEST] 00000088 WebContainerL I WebContainerLifecycle startApplication OpenWebBeans Container is starting...
[8/15/14 12:41:40:556 CEST] 00000088 BeansDeployer I BeansDeployer validateInjectionPoints All injection points were validated successfully.
[8/15/14 12:41:40:571 CEST] 00000088 WebContainerL I WebContainerLifecycle startApplication OpenWebBeans Container has started, it took [78] ms.

UPDATE 2
Here is my simple servlet which works. You probably have some conflicting jars in your WEB-INF/lib folder. Either try to remove conflicting ones, or try with PARENT_LAST class loader.

@WebServlet("/BeanManagerServlet")
public class BeanManagerServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
    @Resource
    private BeanManager bmanager;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.println("Bmanager from annotation: " + bmanager);
        out.println("<BR><BR>");

        try {
            InitialContext ctx = new InitialContext();
            BeanManager bm2 = (BeanManager) ctx.lookup("java:comp/BeanManager");
            out.println("Bmanager from JNDI: " + bm2);
            out.println("<BR><BR>");
            out.println(bm2.getClass().getName());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

// gives output:
Bmanager from annotation: com.ibm.ws.webbeans.services.IBMBeanManagerImpl@ffd28a40 
Bmanager from JNDI: com.ibm.ws.webbeans.services.IBMBeanManagerImpl@ffd28a40
