Injecting bean instances in Servlets/EJBs

[genman]

Looked over the documentation but I didn't really see any explanation or recommendation for how deployed beans are supposed to be accessed through Servlet deployments. Is JNDI the suggested way? Is there support for @javax.annotation.Resource tags for accessing your own beans? (I wonder how JBoss AS implements @Resource...)

JNDI might be okay. If so, how can I be sure the Servlet is initialized AFTER my bean is?

I guess I'm really after something like what Web Beans promises, which is integration of POJOs/dependency injection with JEE.

As an aside, I don't really see any code sharing between Microcontainer, Seam/Web Beans, which is odd, considering the functionality is in many ways similar.

There is simple integration that I wrote for Servlet + MC usage:
- http://anonsvn.jboss.org/repos/jbossas/projects/mc-int/trunk/servlet/
- http://anonsvn.jboss.org/repos/jbossas/projects/mc-tools/grapher/trunk/src/main/java/org/jboss/mctools/grapher/GrapherServlet.java

You can define explicit dependency.
Afaik WebModule - which is how we deploy servlets - has depends notion.
Although I would have to look where you define them.

You could also add it through jboss-dependency.xml:

This is exactly what Kabir is working on now:

Thanks for the info.

I want my Web Beans. Really bad.
