You need to create beans.xml. This should ensure that everything gets scanned:

<?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"
       xmlns:weld="http://jboss.org/schema/weld/beans"
       xsi:schemaLocation="
          http://java.sun.com/xml/ns/javaee http://docs.jboss.org/cdi/beans_1_0.xsd
          http://jboss.org/schema/weld/beans http://jboss.org/schema/weld/beans_1_1.xsd">

    <weld:scan>
        <weld:include name="org.jboss.jawabot.**"/>
    </weld:scan>

</beans>
