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
javax.el.PropertyNotFoundException: //C:/Users/edbuitrago/.jdeveloper/system12.1.3.0.41.140521.1008/o.j2ee/drs/Batch/ViewControllerWebApp.war/index.xhtml @8,49 value="#{batch.name}": Target Unreachable, identifier 'batch' resolved to null

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

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