Subproject dependency injection . jar

Question

I have an app EJB who owns a lib jar as a dependency built for code reuse. My . jar has a class that has been annotated with @RequestScoped, and I need to retrieve it on my ejb.

I’m using the following line, someone knows why it doesn’t work?

MinhaClasse o = CDI.current().select(MinhaClasse .class).get();
return o.getNome();

Error code:

  Caused by: org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001308: Unable to resolve any beans for Type: class br.com.meuprojeto.jpa.MinhaClasse; Qualifiers: []

Answer 1

The Minhaclasse class is not eligible for the CDI.

1. Make sure you’re using CDI @Requestscoped (javax.enterprise.context).
2. Use @Inject to perform the injection. How an EJB is managed by the container, the bean will be injected normally.
3. Make sure your JAR has the Beans.xml file in the META-INF folder.

If none of this solves, you can still create a method annotated with @Produces that returns an instance of the Minhaclasse class. Since the method parameter you can receive what is necessary for creating the instance (the received items by parameter have to be CDI-eligible).
