Error in Bluemix Liberty when injecting a simple CDI managed bean into a servlet

Question

When injecting a simple CDI managed bean into a servlet (starting from the generated code sample "SimpleServlet"), when accessing the servlet, Bluemix Liberty logs this error :

"SimpleServlet cannot be injected as class wasdev.sample.servlet.SimpleServlet is not in a bean archive."

This is so even when a beans.xml file with discovery "all" is used.The target looks like this

public class SimpleServlet extends HttpServlet { private static final long serialVersionUID = 1L; @Inject private TestService svc; — Mustansir Ali, Dec 16 '16 at 00:11

Reason for Error :

The error is due to not having a beans.xml in the built application war i.e. JavaHelloWorldApp.war

Currently, for performance reasons, the beans.xml file is always required in order to use CDI on Bluemix.

Solution :

Copied the bean.xml inside the /src/main/webapp/WEB-INF/beans.xml then built the code.

This made sure that the bean.xml is packaged into the war file i.e. JavaHelloWorldApp.war and the error is resolved.

So the problem was that the beans.xml was not in your war? In the question you stated that the beans.xml was there... – Andy Guibert Dec 15 '16 at 17:48
yes, bean.xml should be there in the war file. I am providing the snapshot below for reference. – Mustansir Ali Dec 16 '16 at 00:02

To verify bean.xml is deployed correctly to Bluemix, select the java application on Bluemix console, click and open the java application dashboard. Select Runtime, select Files tab, browse and verify that the bean.xml is deployed correctly inside WEB-INF as shown in the snapshot below.
