Using @Named annotation in JDevelper and Weblogic

Question

I think that this question is related to mine, but i wouldn't like to add another jar to the project.

I am migrating the java hello1 example (JEE7)(with some modifications that you'll see bellow) from netbeans and Glassfish to JDeveloper 12.1.3 and Weblogic Server 12.1.3.0.0. I'm doing this because I need to start a project with jsf and I need these IDE and Server. The problem is that I can't use CDI with the @Named annotation in my backing bean.

The Libraries added to my project are "JSP Runtime", JSF 2.1 and JSTL 1.2

JDeveloper suggest me "Configure Project for CDI" so It adds a new library, "Contexts and Dependendcy Injection", and beans.xml file under WEB-INF directory.

beans.xml

<?xml version = '1.0' encoding = 'windows-1252'?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd"
       xmlns="http://java.sun.com/xml/ns/javaee"></beans>

When I run the project the response is empty "Hello" and the name property is not showed, but without errors.

If I remove the "Contexts and Dependendcy Injection" library and the beans.xml file then it shows me the following error:

Error 500--Internal Server Error

Everything works fine if I use @ManagedBean annotation instead of @Named annotation. Any suggestions will be appreciated, thanks in advance.

Here is my code

index.xhtml

<?xml version='1.0' encoding='windows-1252'?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html">
    <h:head></h:head>
    <h:body>
        <h:form>
            <h2>Hello, my name is Duke. What's yours?</h2>
            <h:inputText value="#{batch.name}"/>
            <h:commandButton value="Send" action="response"/>
        </h:form>
    </h:body>
</html>

    public Batch(){

        }
    public void setName(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

}

With `@Named` use `import javax.enterprise.context.RequestScoped` — Geinmachi, Oct 14 '15 at 20:54
I changed the import but the same error is depicted. "Target Unreachable, identifier 'batch' resolved to null" — Edu, Oct 14 '15 at 21:01
Thanks a lot! after the change that you suggest me and after adding the library "Contexts and Dependendcy Injection" it works like a charm. It was a noob error. Here is another related question [link](http://stackoverflow.com/questions/30128395/identifying-and-solving-javax-el-propertynotfoundexception-target-unreachable) — Edu, Oct 14 '15 at 21:07

As Geinmachi said I was using the wrong import. In the java ee 7 tutorial you can see an example (example)
