I followed the tutorial to create a very simple EJB3, and a client to test.
Here is the client:

package com.myeclipseide.ejb3;

import javax.naming.InitialContext;
import com.myeclipseide.ejb3.*;
import javax.naming.Context;
import java.util.*;

public class MyBeanClient {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub
        Hashtable<String,String> prop=new Hashtable<String,String>();
        prop.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
        prop.put(Context.PROVIDER_URL, "t3://localhost:7001");
         
        InitialContext ctx = new InitialContext(prop);
        MyBeanRemote bean = ( MyBeanRemote) ctx.lookup("MyBean123#com.myeclipseide.ejb3.MyBeanRemote");
        bean.doSomething(); 
    }

}

I deployed the EJB from MyEclipse on weblogic 10, and seems deployed correctly, here is the log file I got when weblogic started up.

<Module SampleEJBProject of application _appsdir_SampleEJBProject_dir is transitioning from STATE_NEW to STATE_PREPARED on server AdminServer.>
<EJB Deploying file: SampleEJBProject>
<Module SampleEJBProject of application _appsdir_SampleEJBProject_dir successfully transitioned from STATE_NEW to STATE_PREPARED on server AdminServer.>
<Module SampleEJBProject of application _appsdir_SampleEJBProject_dir is transitioning from STATE_PREPARED to STATE_ADMIN on server AdminServer.>
<The EJB ‘MyBean(Application: _appsdir_SampleEJBProject_dir, EJBComponent: SampleEJBProject)’ has been successfully deployed. The following remote interfaces have been bound into JNDI with the specified JNDI names:>
BEA-014022> <******** com.myeclipseide.ejb3.MyBeanRemote is bound with JNDI name:MyBean123#com.myeclipseide.ejb3.MyBeanRemote ********>
<BEA-010009> <EJB Deployed EJB with JNDI name _appsdir_SampleEJBProject_dirSampleEJBProjectMyBean_Home.>
<BEA-149060> <Module SampleEJBProject of application _appsdir_SampleEJBProject_dir successfully transitioned from STATE_PREPARED to STATE_ADMIN on server AdminServer.>

However, when I run the client from MyBeanClient.java, right click, -> run as Java Application, I got this exception:

Anyone knows what is happening, do i missing some configuration, or classpath or something?

BTW, here is what the MyBean.java looks like:

package com.myeclipseide.ejb3;

import javax.ejb.Stateless;

@Stateless(name="MyBean", mappedName="MyBean123")
public class MyBean implements MyBeanLocal, MyBeanRemote {
    public void doSomething() {
        System.out.println("Hello World");
    }
}

Anyone knows what is happening, and helps me?

[freelong]

any idea about from which point I should check?
Thanks a lot.

I seem to have same problem.

My client cant see the remote interface class.
