This is just an FYI for drools users. When deploying an EAR to Glassfish 4 we received an exception about Weld dependency injection.

org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [Injector] with qualifiers [@Default] at injection point [[BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedMethod] @Inject org.sonatype.guice.bean.locators.DefaultBeanLocator.autoPublish(Injector)]

The solution that worked in our case was putting this setting in Glassfish:

asadmin set configs.config.server-config.cdi-service.enable-implicit-cdi=false

That solution is from this forum post (lots more detail there):

Took some time for me to figure out so figured it might help somebody someday.
