Weld cannot find CDI producer - wildfly

Question

WildFly 10.1 used. In modules added single module that contains jar file with interface EzRegistryService.
Producer code:
package com.ejbtest;
import org.apache.log4j.Logger;
import javax.ejb.EJB;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Default;
import javax.enterprise.inject.Produces;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class Resources {
private static final Logger log = Logger.getLogger(Resources.class);
public static final String jndiName = "java:global/ejbtest.main/EzRegistryServiceBean!com.ejbtest.EzRegistryService";
//also didn't work
//#Produces
//#EJB(lookup = jndiName)
//private EzRegistryService ezRegistryService;
// didn't work
#Produces
public EzRegistryService getEzRegistryService() {
log.info("getEzRegistryService called");
try {
InitialContext ctx = new InitialContext();
Object service = ctx.lookup(jndiName);
log.info("Found: " + service);
return (EzRegistryService) service;
} catch (NamingException e) {
log.error("Exception while getting EzRegistryService", e);
return null;
}
}
}
Singleton bean:
package com.ejbtest;
import org.apache.log4j.Logger;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.ejb.EJB;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.inject.Inject;
#Singleton
#Startup
public class MyGateStartup {
private static final Logger log = Logger.getLogger(MyGateStartup.class);
//#EJB(mappedName = Resources.jndiName) //works fine
#Inject
private EzRegistryService service;
#PostConstruct
public void start() {
log.info("MyGateStartup started");
//...
}
#PreDestroy
public void end() {
//...
log.info("MyGateStartup stopped");
}
}
beans.xml in WEB-INF folder:
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"

Why CDI can't find producer in Resources class?

Answer 1

In CDI specification, it is written in section 2.5:
Producer methods (as defined in Producer methods) whose bean class does not have a bean defining annotation are not discovered....
The class where you have your #Produces annotated method must be a CDI bean. Try giving it a scope :)

Answer 2

Looks like CDI is not managing your Resources class.
Once it's just a factory bean, you can annotated it with #ApplicationScoped:
#ApplicationScoped
public class Resources {
...
}
