JavaBeans (EJB) module does not have any enterprise beans configured

Question

I am trying to deploy EAR file on WebShpere 8.5 and I keep getting this error:

com.ibm.ejs.container.EJBConfigurationException: The BackendBE.war Enterprise JavaBeans (EJB) module does not have any enterprise beans configured.

I add backendBE.war to the EAR project I want to install on my server, the error appears after trying to start the server.

Full error log:

com.ibm.ejs.container.EJBConfigurationException: The BackendBE.war Enterprise JavaBeans (EJB) module does not have any enterprise beans configured.

This exception occurs when a WAR module contains an ejb-jar.xml file that does not define any EJBs. When an ejb-jar.xml file is present, it must define at least one EJB, or there must be at least one EJB defined via annotations (like @Stateless) and the ejb-jar.xml and web.xml files must not container metadata-complete=true.
