Dynamic components creating in enterprise application

[xorsolutions]

I'm developing enterprise application using EJB3 + Seam 2.0.1 + RichFaces 3.1.3 + JBoss 4.2.2.
My ejb-module include entity and session beans with Seam annotations. Web-module provide user interface with ajax support refer directly to ejb beans.
I need to create components dynamically (using binding attribute) and provide data exchange between this components and DB. So I try to create a backing bean inside the ejb-module but receive NoClassDefFoundError during project deployment. My richfaces-api.jar is placed in ear/lib directory while richfaces-impl.jar and richfaces-ui.jar in my war/WEB-INF/lib. Say pls where I'm wrong?

Bean's code is like this

@Stateless
@Name("manager")
public class Bean {
 ...
 private HtmlAjaxOutputPanel myPanel;

 public HtmlAjaxOutputPanel getMyPanel() {

 myPanel = new HtmlAjaxOutputPanel();
 ...
 return myPanel;
 }

 public void setMyPanel(HtmlAjaxOutputPanel myPanel) {
 this.myPanel = myPanel;
 }
}

Component's creating is like this

<a4j:outputPanel binding="#{manager.myPanel}" />

I get this while deploying project

Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener
java.lang.NoClassDefFoundError: org/richfaces/component/html/HtmlAjaxOutputPanel;
