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:
java.security.AccessControlException: access denied (java.net.SocketPermission 230.0.0.4 connect,accept,resolve) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264) at java.security.AccessController.checkPermission(AccessController.java:427) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at java.lang.SecurityManager.checkMulticast(SecurityManager.java:1188) at java.net.MulticastSocket.joinGroup(MulticastSocket.java:269) at org.jnp.interfaces.NamingContext.discoverServer(NamingContext.java:1254) at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1382) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:579) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:572) at javax.naming.InitialContext.lookup(InitialContext.java:351) 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(); } } } } } } I don't know hot to modify(add) the my policy file,the new policy file must be which dir?how to add the VM argument use policy file?
