When i have the situation above:
@Alternative
@Stereotype
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface ETC {}
public abstract class BpmExpressionService { public final static String NAME = "bpmExpressionService"; }
@Stateless
@Named(BpmExpressionService.NAME)
public class EppBpmExpressionService extends BpmExpressionService {}
@ETC
@Stateless
@Named(BpmExpressionService.NAME)
public class EtcBpmExpressionService extends EppBpmExpressionService {}
@Stateless
@Specializes
public class EtcmpaBpmExpressionService extends EtcBpmExpressionService {}
beans.xml file:
<beans xmlns="http://java.sun.com/xml/ns/javaee" 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">
<alternatives>
<stereotype> {package}
.ETC</stereotype>
</alternatives>
</beans>
Following validation error occurs:
Caused by: org.jboss.weld.exceptions.DeploymentException:
WELD-001414
Bean name is ambiguous. Name bpmExpressionService resolves to beans [Session bean [class br.com.infox.bpm.cdi.qualifier.EtcmpaBpmExpressionService with qualifiers [@Default @Any @Named]; local interfaces are [EtcmpaBpmExpressionService], Session bean [class br.com.infox.ibpm.event.EppBpmExpressionService with qualifiers [@Default @Any @Named]; local interfaces are [EppBpmExpressionService]]
But CDI specification says :
"When an enabled bean specializes another bean, the other bean is never instantiated or called by the container. Even if the other bean defines a producer or observer method, the method will never be called."
"Furthermore, if the default implementation declares a bean EL name using @Named, the name is inherited by the specializing alternative bean."
