[EJB/JBoss] - error accessing session stateless ejb in separate server
by jboss251268
Hi guys,
I'm developping a J2EE application running into a appl.server jboss-4.0.1sp1 (JVM 1.4.2)and I'm facing a problem that I don't know how to fix it.
For specialization and reuse reasons, I've created a session-stateless ejb and a message bean packed in a .ear file and, in another ear, I've packed all my web-application code, separated in a war (presentation) and another session stateless ejb (business logic).
If I deploy the 2 ear files in the same server my appl work fine, but if I deploy the ears in separate servers, I cannot reach the session stateles EJB with the following error, but I can send a message to the message bean
javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException: it.aztech.signer.AZTECH_SignerRemoteHome (no security manager: RMI class loader disabled)]
I can lookup and use correctly the ejb, and the message bean, from a standalone java application
This is my code for lookup the ejb
public AZTECH_SignerRemote getSignerRemote(String who) throws Exception
{
String NAMING_CONTEXT_FACTORY = "org.jnp.interfaces.NamingContextFactory";
String PROVIDER_URL = "192.168.202.241";
String EJBNAME_SIGNER = "AZTECH_SignerBean";
Hashtable env = new Hashtable();
env.put("java.naming.factory.initial", NAMING_CONTEXT_FACTORY);
env.put("java.naming.provider.url", PROVIDER_URL);
if (who != null)
{
env.put(Context.SECURITY_CREDENTIALS, who);
env.put(Context.SECURITY_PRINCIPAL, who);
}
Context jndiContext = new InitialContext(env);
Object ref = jndiContext.lookup(EJBNAME_SIGNER);
AZTECH_SignerRemoteHome home = (AZTECH_SignerRemoteHome) PortableRemoteObject.narrow(ref, AZTECH_SignerRemoteHome.class);
AZTECH_SignerRemote remote = home.create();
return remote;
}

org.jboss.seam.RequiredException with message: "In attribute requires non-null value: manager.value
I have code

| @Scope(ScopeType.CONVERSATION)
| public class Manager {
