Unable to load the EJB module. DeploymentContext does not contain any EJB

i'm trying to solve this problem since days...

i'm developping a web application and i wish to test my EJBs with arquillian against Payara Server.

Testing EJB fail, returning this full stacktrace:

If you use EJB component annotations to define the EJB, and an ejb or web deployment descriptor is also used, please make sure that the deployment descriptor references a Java EE 5 or higher version schema, and that the metadata-complete attribute is not set to true, so the component annotations can be processed as expected

in my web.xml :

<web-app metadata-complete="false" version="3.1" xmlns="http://ift.tt/19L2NlC" xmlns:xsi="http://ift.tt/ra1lAU" xsi:schemaLocation="http://ift.tt/19L2NlC http://ift.tt/1drxgYl">

at the moment i'm using mockito, but i'd prefer a test in real env.

can someone explain me what happened please?

any suggest will be appreciated
