Create TopicConnectionFactory on LDAP

[Massimo Pascale]

First of all ecuse me for my English.
This is my problem :
I would want to create a TopicConnectionFactory on a server LDAP using JNDI API but I have an Exception as :
LDAP: error code 32 - No such Object
this is th code :
Hashtable env = new Hashtable();
env.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.ldapCtxFactory");
env.put(avax.naming.Context.PROVIDER_URL, "ldap://localhost:389");
DirContext ldp = new InitialDirContext(env);
Context jndiContext = new InitialContext();
TopicConnectionFactory topicConnectionFactory = (TopicConnectionFactory)jndiContext.lookup("TopicConnectionFactory");
ldp.bind("TopicConnectionFactory", topicConnectionFactory); //**********HERE IS THE EXCEPTION

I hope that someone can help me.
Ciao ciao.
