Title: Stateless Session Beans

Describe the issue:
JBoss-specific extensions to the EJB 3.1 specification should be documented. There is for example the possibility to assign a stateless EJB to a particular bean pool. 

Suggestions for improvement:
Add instructions how to assign a bean pool to a stateless EJB, that is using the @org.jboss.ejb3.annotation.Pool annotation, like this:

@Stateless
@Pool("myAwesomePool")
public class HelloBean implements HelloBeanRemote {

    public HelloBean() {
    }

    @Override
    public String hello(String name) {
        return "Hello, " + name;
    }

}

Also please mention that the @Pool annotation is part of the JBoss EJB3 external API and must be added as a dependency, with Maven you can do it this way:

<dependency>
  <groupId>org.jboss.ejb3</groupId>
  <artifactId>jboss-ejb3-ext-api</artifactId>
  <version>2.1.0</version>
</dependency>

Bean pools are discussed in the Admin guide (http://documentation-devel.engineering.redhat.com/docs/en-US/JBoss_Enterprise_Application_Platform/6.2/html/Administration_and_Configuration_Guide/sect-Configuring_Bean_Pools.html) so it would also be useful to add a link to it.
