Hej,
Når jeg kører koden i Solaris unix-maskine, er filen fra eksterne server få downloadet. men når jeg bruger den samme kode i IBM AIX anden maskine, er det ikke kører. Det er at sige "Erro under SCP overførsel." Nedenfor er koden.

Please give nogle beslutning.

SCPClient client \u003d ny SCPClient (conn);
client.get ( "/ home / userid / bin / test.log.gz", "D: \ \");

SCPClient kilde kodestykket nedenfor:

public void get (String remoteFiles [], String localTargetDirectory) throws IOException

tilbagevenden;

Prøv at køre det samme SCP på kommandolinjen for at se, om det giver noget meningsfuldt fejluddata. Dit program over fangster undtagelse og udgange, The InitCause () kode tilsyneladende ikke noget nyttigt.
