Eclipse: EJB and ManagedBean(for JSF)

I'm trying to create some Java EE application. The base is EJB as a controller. Next I want to present the data with JSF+ManagedBeans. The problem is there is

javax.servlet.ServletException: standards/SampleController

java.lang.NoClassDefFoun开发者_JAVA百科dError: standards/SampleController

The Code looks like this:

Managed bean(Dynamic Web Project):WebView project: StdSampleController.java:

import javax.ejb.EJB;

import standards.SampleController;

public class StdSampleController {

    @EJB private SampleController c;
    public String value;

    public StdSampleController() {
        c = new SampleController();
        value = c.getValue();
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

EJB(EJB Project): WebController project: standards.SampleController.java:

package standards;

import javax.ejb.Stateless;

/**
 * Session Bean implementation class SampleController
 */
@Stateless
public class SampleController implements SampleControllerRemote {

    private String value;

    public SampleController() {
        value = "EJB:SampleController bean";
    }

    public String getValue(){
        return value;
    }

}

All this code is put together in an Enterprise Application Project.

I use GlassFish version 3 and Eclipse 3.5.2.

Adding to the answer of unbeli, please remove the following from your code:

public StdSampleController() {
    c = new SampleController();
    value = c.getValue();
}

This is wrong. In the situation you're depicting, c will be injected by the container with a reference to your EJB. Do not instantiate the EJB yourself via the new() operator.

You call your EJB using the (remote) interface, not it's implementation. Therefore, instead of

@EJB private SampleController c;

you need

@EJB private SampleControllerRemote c;

and adjust imports accordingly.
