Injecting a bean from a different Jar in Weld

Question

I have two Jars A and B where A depends on B.

Jar B has a single class:

@ApplicationScoped
public class MyMa         


        

Answer 1

I was having this exact same problem and I was able to get it figured out but I use an ear to combine the jars.

Ear Layout

project.ear
|-- META-INF 
|      |-- MANIFEST.MF
|      |-- application.xml*
|-- one.jar (bean archive)
|      |-- META-INF
|      |      |-- beans.xml
|      |-- <code>
|-- two.jar (ejb)

• application.xml

<application>
  <display-name>test-application</display-name>
  <module>
    <ejb>two.jar</ejb>
  </module>
  <module>
    <java>one.jar</java>
  </module>
</application>

Doing that it made one.jar available to two.jar in the container.

Answer 2

Make sure both jars are "bean archives" - i.e. they have META-INF/beans.xml

Answer 3

One thing, you have to create Qulifier annotation for specify exactly which should be injected.

@Qualifier
@Retention(RUNTIME)
@Target({METHOD, FIELD, PARAMETER, TYPE})
public @interface UserConfiguration { }

and then..

 @Produces
 @UserConfiguration
 @Named("user")
 public String getUser(){
  return "myUser";
 }

for injection..

@Inject
public MyManagedBean(@UserConfiguration String user){
    this.user = user;
}
