GWT : How to use beans from separate module?

Question

I am working on a project with seperated modules . backend for admins , client for users and core for share DAO layer amongs backend and client.
backend module uses GWT and client uses Spring MVC. At backend module , core module was included by deployment assembly. My server side , DAOs are injected by Spring.
All beans(POJOs) created in core module. My problem is I would like to use these beans from core module in my gwt project (backend module) or when using RPC calls.
I tried as answers of How can share bean from external library to GWT client? question but didn't satisfy yet. I got below error

No source code is available for type com.mycom.core.business.bean.TestBean; [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly

Here is my efforted codes ...

TestBean.java

public class TestBean {
private int id;

public final int getId() {
    return id;
}

public final void setId(int id) {
    this.id = id;
}
}

beans.gwt.xml

<?xml version="1.0" encoding="UTF-8"?>
<module>
   <inherits name='com.google.gwt.user.User'/>
   <source path="com.mycom.core.business.bean.TestBean"/>
</module>

Inherit beans.gwt.xml in my App.gwt.xml as <inherits name='com.mycom.backend.beans'/> . What am I missing ?

Edit: Add sample project file

Now I created and uploaded sample modules. You can download it from google-drive URL.This archive file contains both backend and core modules.

core module was created as simple java project from Eclipse IDE.
backend module was created by gwt-ecliplse plugin (2.7 gwt version and include generated codes) and add Dynamic Web Module 2.5 project faces.

Finally , I build and run with GWT-Eclipse plugin and you can check screen-shoot for

The source path of your core module should be accessible to the GWT compile process. Make sure that it is added to either the classpath or the source lookup path.
