RESTEasy CDI on Tomcat 7 Exceptions on deployment

Question

I'm trying to deploy a web application on Tomcat 7.0 using RESTEasy 3.0.6 for RESTful service support. However, when I try and deploy the application, I get the following Exception:

2014-04-09 11:25:27 DEBUG CdiInjectorFactory:68 - Doing a lookup for BeanManager in java:comp/BeanManager

I've followed the instructions on how to incorporate RESTEasy-CDI into my Maven build, and I see the WAR is being built correctly. However, I still see the Exceptions when I deploy.

The relevant portions of my web.xml file look like this:

  <listener>
    <listener-class>
            org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
        </listener-class>
  </listener>
  <listener>
    <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
  </listener>
    <filter>
        <filter-name>ConversationPropagationFilter</filter-name>
        <filter-class>org.jboss.weld.servlet.ConversationPropagationFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>ConversationPropagationFilter</filter-name>
        <url-pattern>*</url-pattern>
    </filter-mapping>

  <resource-env-ref>
    <description>Object factory for the CDI Bean Manager</description>
    <resource-env-ref-name>BeanManager</resource-env-ref-name>
    <resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type>
  </resource-env-ref>
  <servlet>
    <servlet-name>Resteasy</servlet-name>
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
    <init-param>
      <param-name>javax.ws.rs.Application</param-name>
      <param-value>com.myapp.web.rest.JaxRsActivator</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>Resteasy</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>
  <context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rest</param-value>
  </context-param>

Any idea what might be causing this or how to get around this error? At this point, it is basically a show-stopper.

Answer 1

Found the issue. It was merely a servlet listener ordering problem. I was initializing RESTEasy prior to initializing CDI.
