[jcifs] Having problem with simply connecting with release 1.2.9

[Thomas Bley]

Hi,

I also had this Exception with listFiles() (no OutputStream).
When running with JRE, Cp850 is not supported and the 
NullpointerException comes up.
I'm using this code to decide the right encoding for jCIFS:

if (java.nio.charset.Charset.isSupported("IBM850")) { // JDK
  jcifs.Config.setProperty( "jcifs.encoding", "Cp850" );
} else { // JRE
  jcifs.Config.setProperty( "jcifs.encoding", "Cp1252" );
}

Using Cp1252 the German Umlaute are not working in shares names, but 
that's not so bad.

Best regards,
Thomas Bley
