[jboss-user] [JNDI/Naming/Network] - javax.naming.CommunicationException - no security manager: R
Hi!
I'm working on an application with a client and a server. I'm using JBoss 4.2 and
Java 1.6.
On client side I bind an object to JNDI and try to lookup this object on server side.
CLIENT:
Object callback = ...;
| Properties p = new Properties();
| p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
| Context context = new InitialContext(p);
| context.bind (newBindName, callback); // Bind the callback object to JNDI
This is the Callback class:
public class Callback
| implements BCServiceProxy, Serializable, Remote {
|
| /**
| * Logger
| */
| private static final Log log = LogFactory.getLog (Callback.class);
|
| /**
| * The listener to be notified about new postboxentries
| */
| private transient PostboxListener postboxListener;
|
| /**
| * Constructor
| * @param postboxListener listener to be notified about new postboxentries
| */
| public Callback (PostboxListener postboxListener) {
| this.postboxListener = postboxListener;
| }
|
| /**
| * @inheritDoc
| */
| public String gotPostboxEntry (PostboxEntry postboxEntry) {
| String rc = null;
| if (postboxListener!=null) {
| rc = postboxListener.gotPostboxEntry (postboxEntry);
| }
| return rc;
| }
|
| }
After the binding I can see the object at the JNDIView in Global JNDI Namespace:
+- a5xk891BCServiceProxyPostboxTask 41232010727767 (class:
de.postbox.proxies.bcservice.Callback)
SERVER:
The remote interface BCServiceProxy which the Callback class implements is in a JAR which
is deyploed on the server.
public interface BCServiceProxy
| extends Serializable, Remote {
|
| /**
| * Called when the next postboxentry is known
| * @param postboxEntry the next postboxentry
| * @return String the id of the workitem, which should be delivered next.
| * For null the order of the delivered postboxentries will not be
modified
| * @throws RemoteException
| */
| public String gotPostboxEntry (PostboxEntry postboxEntry) throws RemoteException;
|
| }
Now I try to make the lookup on server side:
Properties p = new Properties();
| p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
| Context context = new InitialContext(p);
| Object objref = context.lookup(requestorbindname);
This results in an exception:
javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException:
No ClassLoaders found for: de.postbox.proxies.bcservice.Callback (no security manager: RMI
class loader disabled)]
Why do I get this exception?
Is it because I see the concrete class in JNDIView (see above). Shouldn't I see there
something like this: +- a5xk891BCServiceProxyPostboxTask 41232010727767 (proxy: $Proxy99
implements interface de.postbox.services.bcservice.proxy.BCServiceProxy)?
Any help will be greatly appreciated!
