If you are just starting out with JEE CDI (Weld), it’s easy to forget the required beans.xml file. If you don’t include it, you may run into problems like this:
SEVERE: javax.el.PropertyNotFoundException: /index.xhtml @8,67 action="#{crm.ping}": Target Unreachable, identifier 'crm' resolved to null
javax.faces.el.EvaluationException: javax.el.PropertyNotFoundException: /index.xhtml @8,67 action="#{crm.ping}": Target Unreachable, identifier 'crm' resolved to null
at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:95)
at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:102)
at javax.faces.component.UICommand.broadcast(UICommand.java:315)
...
The beans.xml file (in META-INF/classes or WEB-INF/) can be empty or contain the following:
<?xml version="1.0" encoding="UTF-8"?>
<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">
</beans>
