[cdi-dev] [JBoss JIRA] Commented: (CDI-117) Add BeanManager to a ServletContext attribute

[George Gastaldi (JIRA)]

    [ https://issues.jboss.org/browse/CDI-117?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12597715#comment-12597715 ] 

George Gastaldi commented on CDI-117:
-------------------------------------

What about using java.util.ServiceLoader? That would lead to standard service locator approach, without the need for factories.

> CDI 1.0 defines a JNDI lookup as the standard way to obtain the BeanManager for resources not managed by the CDI environment. However in a servlet environment it would be much easier to get the BeanManager from a standardized servlet context attribute. This would be also a major simplification in environments that don't support JNDI (for example GAE) or that don't allow to use the standard JNDI name for the BeanManager (for example Apache Tomcat).
> This topic was already discussed on weld-dev about a year ago [1]. Weld 1.0 already supports this [2] and OpenWebBeans also added this feature [3]. Unfortunately Weld 1.1 changed the attribute to a Weld-specific name in [4] which currently leads to much confusion [5].
> As both of the major CDI implementations support this feature I think it should finally be put into the spec.
