      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:

      java.security.AccessControlException: access denied (java.net.SocketPermission 230.0.0.4 connect,accept,resolve)

      at product.client.ProductClient.main(ProductClient.java:47)


      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();
      }
      }
      }
      }
      }
      }
