How To Discover All Deployed Beans

import javax.enterprise.inject.Any;
import javax.enterprise.inject.spi.Bean;
import javax.enterprise.inject.spi.BeanManager;
import javax.enterprise.util.AnnotationLiteral;

BeanManager beanManager;

Set<Bean<?>> beans = beanManager.getBeans(Object.class,new AnnotationLiteral<Any>() {}));
        for (Bean<?> bean : beans) {

Enjoy discovering!

See you at Upcoming Java EE Workhops at MUC Airport!


Cool! BeanManager is new for me. Nice to know. Tnx.
BTW the "private" keyword can be left out ;-) (

I think there is something missing in the beans declaration. Am I wrong?

Nice one! Is there a recipe for Java EE 5, too?

Hi Ivar,

sorry for the bloat--I removed "private",

you are not wrong--I always forget to escape generics (lesser than, greater than characters) and they are going to be swallowed by the browser.

Not it is fixed!,

Adam, how can I get an instance of the bean.getBeanClass()?

I tried:

CreationalContext<?> creationalContext = beanManager.createCreationalContext(bean);
beanManager.getReference(bean, bean.getBeanClass(), creationalContext);

It worked, Is it right?
