Using annotated servlet listeners from modules

PicketLink provides support for Http Security. Basically, it consists of an API to define security policies to the paths or resources of an application and a security filter (servlet filter) that is responsible to enforce those policies for every single request.

The security filter is installed from a specific ServletContextListener (org.picketlink.http.internal.PicketLinkServletContextListener) that checks if the application has defined any security policy in order to decide if the filter must be installed or not.

PicketLink also defines a ServletRequestListener (org.picketlink.http.internal.HttpServletRequestListener) that is used to produce a decorated HttpServletRequest instance. This decorated instance provides full integration between PL and the HttpServletRequest security methods plus some other goodies for PL users such as URL rewriting, etc.

Both listeners (servletcontext and request) are CDI beans with injection points and/or producer methods.

When using PL from modules, the producer method of org.picketlink.http.internal.HttpServletRequestListener#produce is not being recognized. And that makes impossible to use PL from modules.

The same code works if you use PL jars inside the deployment.

Another interesting behavior is that EAP and WildFly are behaving differently. In EAP (latest build), the ServletContextListener is only recognized as a CDI bean if you define it in the web.xml. While in WildFly this is not necessary.

Also, in EAP the producer method of HttpServletRequestListener is properly recognized and everything works fine.

I've created a branch [1] to test this issue. The test case is

org.wildfly.test.integration.security.picketlink.core.http.ServletListenerFromModuleTestCase
