ClassCastException java RMI

[AF.D.O.C]

Salve a tutti
Ho un problema che non riesco a risolvere =(

quando eseguo il codice al momento che richiamo un metodo remoto ho questo errore:

java.lang.ClassCastException: cannot assign instance of $Proxy1 to field Classi.info_client.cb_client of type Client.cb_client_implements in instance of Classi.info_client

ho controllato che tutti i tipi coincidano e non faccio nessun tipo di cast

non sò più dove sbattere la testa, qualcuno può aiutarmi??

Grazie mille! =)

Posto il codice dove ho l'errore!!

Usa il tag CODE, come indicato nel Regolamento.

[valia]

e potevi anche evidenziare in qualche modo la riga in cui si genera l'errore.
cmq anche se tu esplicitamente non fai cast, un cast viene fatto e te lo dice qui

java.lang.ClassCastException: cannot assign instance of $Proxy1 to field Classi.info_client.cb_client of type Client.cb_client_implements in instance of Classi.info_client

prova a ricontrollare l'operazione che fai nella riga incriminata, che dal codice scritto cosi è difficile dedurre
