[Java] SSL - Connection refused: hostname (/etc/host) non riconosciuto

[VincDis84]

Ciao a tutti,
sono alla disperata ricerca di una soluzione in ambito di Sicurezza dei Web service.

In pratica vorrei instaurare una connessione sicura, tramite SSL, tra Client (Servlet) ed un EAR (Web Service EJB) entrambi che girano nello stesso Application Server (JBoss-4.2.3.GA).

All'interno della Servlet specifico un indirizzo ip al quale deve connettersi (sarebbe quello della macchina in cui gira l'Application Server) e tale indirizzo ip è mappato all'interno del file "hosts" nel seguente modo:

[indirizzo ip]    Prova_svil_GeV

Questo stesso alias è cablato all'interno del codice della Servlet per definire l'URL al quale, come già detto, deve connettersi.

Purtroppo, così facendo, la Servlet non si connette restituendomi questa essezione:

Nel momento in cui, invece, impostando nel file hosts (e conseguentemente nel codice della Servlet) il seguente valore:

[indirizzo ip]        ProvaSvilGeV                      (....in pratica togliendo gli "_")

il tutto funziona senza problemi!!!

Questo problema si ripete sia in ambiente WINDOWS  che in ambiente LINUX.

Ma non è che per caso, sia Windows che Linux, non riescono a mappare nomi di host con gli "_" (underscore)?

Grazie mille in anticipo per il supprto.....
