-----------------------------------
Have you put {{beans.xml}} into {{META-INF}} to initialise CDI?

> Hello,
> I'm trying to get CDI (WELD) to work on our Java EE application. We use Struts2 as front-end framework with Action classes (as controllers).
> We want to be able to use CDI and inject into the Action classes but we have no success on integrating the cdi-plugin.
> On weblogic server startup I get the following error:
> {noformat}

> I checked out the source code and I could see that the beanManager instance variable is NULL. This happens because none of the 3 lookups is able to get a reference to the BeanManager.
