[jboss-user] [EJB/JBoss] - error accessing session stateless ejb in separate server

[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;
	}
