[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - The CMP development Problem!!!

[chengshan]

When I develop a CMP ,I meet a problem,My env is :
1.dev env:Jbuilder;
2.run env:jboss 4.0,jdk1.5
3.I develop it ,when I deloply success,run my test client,the console information looks like:

My test client is like this:

package product.client;

import javax.ejb.*;
import javax.naming.*;
import java.rmi.*;
import javax.rmi.PortableRemoteObject;
import java.util.*;
import product.ProductHome;
import product.Product;

public class ProductClient {
    public ProductClient() {
    }

    public static void main(String[] args) throws Exception {
        ProductClient productclient = new ProductClient();
        ProductHome home = null;

        try{

            System.setProperty("java.security.policy","policy");

            System.setSecurityManager(new RMISecurityManager());

            //if(System.getSecurityManager() == null)
            //    System.setSecurityManager(new RMISecurityManager());

            Hashtable props = new Hashtable();
            props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
            props.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
            props.put(Context.PROVIDER_URL,"jnp://localhost:1099");

            Context ctx = new InitialContext(props);
            home = (ProductHome)ctx.lookup("ProductBean");

            //Object obj = ctx.lookup("ProductBean");
            //if(obj == null)
            //    System.out.println("ProductBean is null");

            //home = (ProductHome)PortableRemoteObject.narrow(obj,ProductHome.class);

            home.create("100","P5-350","350 MHZ Pentium",200);
            home.create("101","P5-400","400 MHZ Pentium",300);
            home.create("102","P5-450","450 MHZ Pentium",400);
            home.create("103","SD-64","64MB SDRAM",50);
            home.create("104","SD-128","128MB SDRAM",100);
            home.create("105","SD-256","256MB SDRAM",200);

            Iterator i = home.findByName("SD-64").iterator();
            System.out.println("These products match the name SD-64:");
            while(i.hasNext()){
                Product prod = (Product)i.next();
                System.out.println("prod.getDescription()"+prod.getDescription());
            }
            System.out.println("Finding all Products that cost $200");
            i = home.findByBasePrice(200).iterator();
            while(i.hasNext()){
                Product prod = (Product)i.next();
                System.out.println("prod.getDescription"+prod.getDescription());
            }
        }catch(Exception e){
            e.printStackTrace();
        }finally{
            if(home != null){
                System.out.println("Destroying products....");
                Iterator i = home.findAllProducts().iterator();
                while(i.hasNext()){
                    try{
                        Product prod = (Product)i.next();
                        if(prod.getProductId().startsWith("123")){
                            prod.remove();
                        }
                    }catch(Exception e){
                        e.printStackTrace();
                    }
                }
            }
        }
    }
}
