EJB Remotamente?

Programação Java
#1

Pessoal,
Estou acessando os ejbs remotamente da seguinte forma:
java -Dorg.omg.CORBA.ORBInitialHost:myserver -classpath “$CLASSPATH” classeCliente
Funciona normalmente.
Teria outra forma de estar acessando os ejbs em outras máquinas sem usar esse argumento ?

Tentei:

Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY, “com.sun.jndi.cosnaming.CNCtxFactory” );
env.put( Context.PROVIDER_URL, “iiop://myserver:1050” )
try {
Context jndi = new InitialContext( env );
…
}
catch( Exception e ) {…}

mas não funcionou.

Alguém teria uma sugestão ?

obrigado.

creio q copiando as interfaces remotas e pegando a referencia vc consegue.

ex:

Context ctx = new InitialContext();
Object ref = ctx.lookup( "ejb_MeuEJB" );
MeuEJB interfaceRemota = (MeuEJB)PortableRemoteObject.narrow( ref, MeuEJBHome.class );

onde:
MeuEBJ é uma inteface remota
MeuEJBHome é a interface Home
e
ejb_MeuEJB é o nome do EJB no descritor

Pessoal,
Tentei também:

		Properties properties = new Properties();
		properties.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
		properties.put("java.naming.provider.url", "iiop://192.168.0.71:1050");
		Context initial = new InitialContext(properties);

nos dois jeitos os erros são muito parecidos:
