 |
|
ciao,
ho server java che ora gira su linux. La connessione rmi dall'esterno funziona (quindi oggetti corretamente registrati a rmi registry) ma connessione da locale (verso 127.0.0.1 o ip address) non funziona e mi da' eccezione Unknown Host Exception ipaddress.
qualche idea?Sembra problema di indirizzamento............
grazie |

ciao eccezione viene generata non quando il client tenta la connessione con lookup (sia con agentIp=127.0.0.1 che ipAddress=172.16.241.97) ma quando chiama il metodo che realizza il servizio.
Lo stesso codice da remoto funziona
| Code: |
url = "//" + agentIp + ":1101/SocketAlarmSS";
if (alarmManager==null)
{
try {
alarmManager = (AlarmManager) Naming.lookup(url);
}
catch (Exception e) {
System.out.println("connectToAgentAndCall:: CANNOT CONNECT TO AGENT " + url+" "+e.getMessage());
System.exit(1);
}
}
try {
retCode=alarmManager.genericService(serviceName,cmdAction,params);
}
catch (Exception e) {
System.out.println("connectToAgentAndCall::service call remote exception " + url+" " +e.getMessage());
System.exit(1);
}
|
Eccezione riportata' e':
| Code: |
service call remote exception //127.0.0.1:1101/SocketAlarmSS Unknown host: 172.16.241.97 ; nested exception is:
java.net.UnknownHostException: 172.16.241.97
|
Se uso ip address ottengo la stessa cosa
| Code: |
service call remote exception //172.16.241.97:1101/SocketAlarmSS Unknown host: 172.16.241.97 ; nested exception is:
java.net.UnknownHostException: 172.16.241.97

Il file di policy passato al server e' questo
| Code: |
grant {
permission java.security.AllPermission;
};
/*
grant codeBase "file:${java.home}/lib/ext/*" {
permission java.security.AllPermission;
};
grant {
permission java.lang.RuntimePermission "stopThread";
permission java.net.SocketPermission "*:1-", "listen, accept, connect, listen, resolve";
permission java.util.PropertyPermission "java.version", "read";
permission java.util.PropertyPermission "java.vendor", "read";
permission java.util.PropertyPermission "java.vendor.url", "read";
permission java.util.PropertyPermission "java.class.version", "read";
permission java.util.PropertyPermission "os.name", "read";
permission java.util.PropertyPermission "os.version", "read";
permission java.util.PropertyPermission "os.arch", "read";
permission java.util.PropertyPermission "file.separator", "read";
permission java.util.PropertyPermission "path.separator", "read";
permission java.util.PropertyPermission "line.separator", "read";
permission java.util.PropertyPermission "java.specification.version", "read";

permission java.util.PropertyPermission "java.vm.version", "read";
permission java.util.PropertyPermission "java.vm.vendor", "read";
permission java.util.PropertyPermission "java.vm.name", "read";
permission java.util.PropertyPermission "user.dir", "read";
permission java.util.PropertyPermission "JAVLIN_HOME", "read";
permission java.io.FilePermission "<<ALL FILES>>", "read, write, delete";
permission java.util.PropertyPermission "*", "read, write";
};
*/

Sembra sia tutto commentato tranne la prima grant. Se a tale
grant aggiungo anche permission java.net.SocketPermission.AllPermission le cose non migliorano
grazie ciao |
