I would like to inject a bean into an servlet filter as described under https://stackoverflow.com/a/7815328/802058 but it does not work for me. My configuration is:

@FacesConfig(
    version = Version.JSF_2_3
)
@Named
@SessionScoped
public class FooBean implements Serializable {

@WebFilter("/foo.xhtml")
public class FooFilter implements Filter {
    @Inject
    private FooBean fooBean;

WEB-INF
    lib
        javax.faces-2.3.0.jar
        omnifaces-1.14.1.jar
        weld-servlet-shaded-3.0.2.Final.jar
beans.xml (empty)

Error messages from Tomcat after starting:

What's wrong?

CDI/Weld can't find a matching bean because of @FacesConfig qualifier (that's what the stracktrace tells you). Add @Default qualifier to FooBean. The @Default qualifier is the qualifier that a bean has if it doesn't explicitly specify a qualifier.

Alternatively you could add @Any qualifier to your injection point. As the name suggests any bean has the @Any qualifier by default.

  • Okay, if I remove the Faces Config tag than it works. But it's not clear for me why this tag confuses the wild behaviour. I need this tag because otherwise some 2.3 features does not work at all (see https://github.com/javaee/glassfish/issues/22094). – Toru Feb 28 '18 at 06:52
