Hi,

Just a question, how can I see if my Bean is correctly named in the
JNDI server. Maybe is not a mystake in my code but simply that the
JNDI name doesn't exist at all ?

Do you know how can I check this ?

Thanx.

Try to list and print out the JNDI-bindings.

NamingEnumeration ne = ctx.listBindings("");
while(ne.hasMore()).... etc...
You might have to step further down the JNDI-namespace, i.e
NamingEnumeration ne = ctx.listBindings("ejb");

Hi everybody,

so I corrected 1-2 bugs. I don't know why but the the error was in my
xml file. So know the ejb is deployed correctly now and I tried the
url that you mentionned and i got this :

jboss.j2ee
jndiName=HelloHome,plugin=pool,service=EJB
jndiName=HelloHome,service=EJB
jndiName=ejb/converter/Converter,plugin=pool,service=EJB
jndiName=ejb/converter/Converter,service=EJB
jndiName=ejb/mgmt/MEJB,plugin=pool,service=EJB
jndiName=ejb/mgmt/MEJB,service=EJB
module=HelloWorld.jar,service=EjbModule
module=converter.jar,service=EjbModule
module=ejb-management.jar,service=EjbModule
service=EARDeployer

Does it means that's ok ?

But know I got another error code when I launch my test client :

javax.naming.CommunicationException: Receive timed out. Root
exception is java.net.SocketTimeoutException: Receive timed out

at java.net.PlainDatagramSocketImpl.receive(Native Method)

at javax.naming.InitialContext.lookup(InitialContext.java:347)
at tests.Test.main(Test.java:23)
Exception in thread "main"


My test client code :

import exemples.Hello;
import exemples.HelloHome;

/**
*
*/
public class Test extends java.lang.Object {

public static void main(String[] args) throws Exception{

Properties p = new Properties();
p.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
p.put("java.naming.factory.url.pkgs","org.jboss.namingrg.jnp.interfaces");
p.put("java.naming.provider.url.package","localhost:1099");
InitialContext ic = new InitialContext(p);
Object obj = ic.lookup("HelloHome");

HelloHome home = (HelloHome) PortableRemoteObject.narrow(obj,
HelloHome.class);
Hello hello = home.create();
System.out.println(hello.hello());
hello.remove();

}

}


Could you help me ?


thanx !!!

Yes.

^^^^^^^^
The key is wrong here - it should be "java.naming.provider.url". You'd
better take the constants:

p.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.setProperty(Context.PROVIDER_URL, "localhost:1099");
p.setProperty(Context.URL_PKG_PREFIXES,
"org.jboss.namingrg.jnp.interfaces");

That should work.
