failed to implement a stand alone java client calling to EJB

[amitguz]

Hi All,
I'm using JBOSS 4.0.3 and my stand alone client failed to connect to EJB.

I tried to implement it as follow :

in the server side :
I create a stateless AuthorBean class which implements Authors Remote interface


in the client side I wrote :

Properties jndiProps = new Properties();
 jndiProps.setProperty(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
 jndiProps.setProperty(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
 jndiProps.setProperty(Context.PROVIDER_URL, "jnp://localhost:1099");
 Context c = new InitialContext(jndiProps);
 Object reference = c.lookup("Authors");

but I'm receiving the following error:

javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost:1099 and discovery failed with error: java.security.AccessControlException: access denied (java.net.SocketPermission 230.0.0.4 connect,accept,resolve) [Root exception is javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)]]

 at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:572)
 at javax.naming.InitialContext.lookup(InitialContext.java:351)
 at client.startApplication.main(startApplication.java:29)

What I'm doing wrong ?
Can someone point me to an example of how to implement such call
from stand alone client to ejb on JBOSS?

tnx, amit

found the problem.
I needed set the security.
add new file to the client side
policy.all which contain :

grant {
 permission java.security.AllPermission "", "";
};

and run the client VC with -Djava.security.policy=policy.all

but now I lookup failed with:

javax.naming.NameNotFoundException: authors not bound

Did you solve it? I have the same problem, too. There are no examples on how to find (lookup) deployed EJB from VM other then EJB containers. When I look in JNDI tree in JMX console, and compare it to what InitialContext contains, I see that it does not search through java namespace, but only through global JNDI namespace.
Here is the code:

InitialContext ctx;
 try {
 ctx = new InitialContext();
 Enumeration ctxList = ctx.list("");
 int i = 0;
 while (ctxList.hasMoreElements()) {
 i++;
 NameClassPair element = (NameClassPair) ctxList.nextElement();
 System.out.println("element "+i+" : "+element);
 }
 } catch (NamingException e) {
 e.printStackTrace();
 }

the JNDI rules are like that:
under JAVA : u can reach JNDI names only from the same VM which JBOSS use, meaning if your client is a standalone client (on a separate VM) and your JBOSS run on a different VM u cannot fetch the namespaces in this area from the client.
under GLOBAL: u can fetch the objects from the JNDI even from different VM.

my problem was that my remote interface wasn't written to the global JDNI due to bye mistake I assign both the local and the remote to the same interface.
@local
@remote
public interface Authors {
dddd,,,,
}
