Hello Bryant;

AFAIK from your context, you want to add your = own JSR-299 beans into the container. So you can extend the container beans= with using Extensions. So, you create a class that implements javax.enterp= rise.inject.spi.Extension and put it into  the classpath "META-INF/ser= vices" with file name "javax.enterprise.inject.spi.Extension" name.

= In this class, you could observe the AfterBeanDiscoveryEvent event like thi= s

public class MyExtensionForCustomBean implements javax.enterprise= .inject.spi.Extension
{
     public void observe(= @Observes AfterBeanDiscoveryEvent event){
        &n= bsp;    event.addBean("Your custom bean")     = ;       
   }
}

Your custom bean might be
public class MyCustomBean exten= ds OwbBean or Bean {

     Add your bean methods<= br>}


BeanManager#createAnnotatedType
BeanManager#createInject= ionTarget

methods are used for non-contextual components for injecti= ng the JSR-299 dependencies. For example, if you have a servlet instance an= d would like to inject JSR-299 dependencies for it, you could do this with = above methods like we did for Apache Tomcat integration.

For example= : We have a non-contextual servlet instance ServletInstance

Create = injection target with BeanManager#createInkectionTarget(....)
InjectionT= arget.inject(servletInstance)

When servlet instance is destroyed, it= s dependencies must also be destroyed via call to
CreationalContext # re= lease(). So you have to call CreationalContext#release method.

I hop= e it helps;

Thanks;

Subject: Creating a contextual managed bean by using BeanMana= ger?

Hi,

I was looking to create managed bean instance= s dynamically for an
Apache Wink (JAX-RS) plugin.

I found the Bea= nManager interface and was hoping that would be a good
way to get my ins= tances via a programmatic interface.  Is that a
possible route for = me to take?

So pseudcode-ish, I would do:

BeanManager beanMan= ager =3D ...
Class<T> managedBeanClass =3D ...
AnnotatedType aType =3D = beanManager.createAnnotatedType(managedBeanclass);
InjectionTarget<T&= gt; iTarget =3D beanManager.createInjectionTarget(aType);

/* is this= the way to get the right creational context? */
Set<Bean<?>>= ; beans =3D beanManager.getBeans(managedBeanClass, (any
qualifier annota= tions here));
Bean bean =3D beans.iterator().next();
CreationalContex= t creationalContext =3D beanManager.createCreationalContext(bean);

T= instance =3D iTarget.produce(creationalContext);
iTarget.inject(instanc= e, creationalContext);
iTarget.postConstruct(instance);

/* ...use= the instance... */

iTarget.preDestroy(instance);
iTarget.dispose= (instance);

/* do I need to do a creationalContext.release()? */
=
I'm hoping the created instance will be correctly injected/disposed of<= br>and would be correctly scoped (i.e. if it's in a servlet container andthe managed bean was @ApplicationScoped then the above code would
still "do= the right thing" instead of creating a new instance).

Thanks for an= y pointers anyone can provide.
