Ken,
Here is the code which worked for me.
package com.ebd.ejb;
import com.ebd.ejb.CabinHome;
import com.ebd.ejb.Cabin;
import com.ebd.ejb.CabinPK;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.rmi.RemoteException;
import javax.rmi.PortableRemoteObject;
import java.util.Properties;
import javax.ejb.CreateException;
public class CabinSessionClient
{
public static int SHIP_ID = 2;
public static int BED_COUNT = 3;
public static void main(String [] args)
{
try
{
Context jndiContext = getInitialContext();
Object ref = (TravelAgentHome)
jndiContext.lookup("TravelAgentBean");
TravelAgentHome home = (TravelAgentHome)
PortableRemoteObject.narrow(ref,TravelAgentHome.class);
TravelAgent reserve = (TravelAgent) home.create();
String [] list = reserve.listCabins(SHIP_ID,BED_COUNT);
System.out.println("Results ="+list.length);
for(int i=0;i<list.length;i++)
{
System.out.println(list[i]);
}
}
catch(java.rmi.RemoteException re)
{
re.printStackTrace();
}
catch( Throwable t)
{
t.printStackTrace();
}
}
public static Context getInitialContext() throws
javax.naming.NamingException
{
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
p.put(Context.PROVIDER_URL,"localhost");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming");
System.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url",
"localhost:1099");
Context ctx = new javax.naming.InitialContext();
return ctx;
}
}
