"type" cannot be resolved to a type, while using ejb in jsp

I use eclipse Neon.
I created simple EJB project with follow code:

package com.clientManager;

import javax.ejb.LocalBean;
import javax.ejb.Stateless;

/**
 * Session Bean implementation class ClientManager
 */
@Stateless
@LocalBean
public class ClientManager {

    /**
     * Default constructor. 
     */
    public ClientManager() {
        // TODO Auto-generated constructor stub
    }

    public String test() {
        return "test";
    }
}

It created automatically and reside in ejbModule folder.
It uses EJB 3.2 and successfully deploying on WildFly server: 

11:25:50,360 INFO  [org.jboss.as.server.deployment] (MSC service thread 1-3) WFLYSRV0028: Stopped deployment Neoflex.jar (runtime-name: Neoflex.jar) in 9ms

11:25:55,523 INFO  [org.jboss.as.server] (DeploymentScanner-threads - 2) WFLYSRV0010: Deployed "Neoflex.jar" (runtime-name : "Neoflex.jar")

Now I created DynamicWebProject for JSP page which will use the EJB: 

<%@page import="com.clientManager.*"%>
<%
    ClientManager c = new ClientManager(); 
%>
<%= c.test() %>

I configured in Build Path of JSP project the EJB project (!)
Please see screenshot.

When I publish JSP and access to the page (main.jsp), I have: 

JBWEB004060: An error occurred at line: 3 in the jsp file: /main.jsp
ClientManager cannot be resolved to a type
1: <%@page import="com.clientManager.*"%>
2: <%
3:  ClientManager c = new ClientManager(); 
4: %>
5: <%= c.test() %>

What is wrong?

You shouldn’t directly instantiate the EJB bean rather it lifecycle in managed by the EJB container, the right way of getting the EJB bean handle is via it's look up method.

Make sure you choose the correct look up name, I am using randomly the one from your post Try changing to something like below.

<%
    ClientManager cm;
    cm = (ClientManager) ctx.lookup("java:module/ClientManager");
%>
