How to access an EJB from a web application deployed in the same server

Question

Hey All,
I deployed an EJB named EventServerBean to Sun Application Server 9.0, and put the client side jar file (named eventserver.jar which is generated by Sun Application Server) to C:\Sun\AppServer\lib. Now, I have a web application which is a simple jave file -- lookup EventServer EJB and invoke a remote method in this EJB. However, the web application always throws an exception "java.lang.NoClassDefFoundError: eventserver/EventServerRemoteHome"
Here is my java class that access the ejb:
public class Post_Event {
    public HashMap<String, String> getEventInfo(String event_name, String site) {
        System.out.println("Post_Event, the class path: " + System.getProperty("java.class.path"));       
        System.out.println("Post_Event, user.dir: " + System.getProperty("user.dir"));
        System.out.println("Post_Event, java.library.path: " + System.getProperty("java.library.path"));
        HashMap<String, String> result = null;
        EventServerRemote remote = null;
        StringTokenizer st, st2;
        // here get the event information from host
        try {
            String lookupStr = "corbaname:iiop:" + site + ":3700#ejb/EventServerBean";
            InitialContext initialContext = new InitialContext();
            EventServerRemoteHome remoteHome = (EventServerRemoteHome) javax.rmi.PortableRemoteObject.narrow(initialContext.lookup(lookupStr), EventServerRemoteHome.class);
            if (remoteHome != null) {
                remote = remoteHome.create();
        } catch (javax.naming.NamingException ne) {
            ne.printStackTrace();
            return null;
        } catch (javax.ejb.CreateException ce) {
            ce.printStackTrace();
            return null;
        } catch (java.rmi.RemoteException re) {
            re.printStackTrace();
            return null;
        } catch (java.io.IOException ioe) {
            ioe.printStackTrace();
            return null;
        System.out.println("look up remote event server successfully.");
     result = remote.getEvent(event_name);
        return result;
    } I output the class path in this java file, and the class path DOES include the path C:\Sun\AppServer\lib where eventserver\EventServerRemoteHome.class is.
Does anyone know why it happens? Why a java class can't find a class that is in its class path?
appreciate any help!

Thank you for your great topic.
I think you need to copy the snippet code and past it to every application, applet, servlet or JSP every time you need to use your EJB.
Its better to include this snippet code in a simple JavaBean and use this bean as a bridge to your EJB, you may include a connect method in your JavaBean or but the connection code in the constructor and include a setters, getters and other methods to encapsulate your EJB methods.
You can use your JavaBean in any application, applet, servlet or JSP just create an object form it and call its methods.
Its just an idea
I hope it will be useful.
