[jcifs] DFS and NetworkExplorer

[Thomas Bley]

Hi,

Looking into the code, I made this change in SmbFile.java:

    String getDfsUncPath0() throws SmbException {
        getUncPath0();
        if( dfsReferral == null ) {
            return null;
        }
        unc = dfsReferral.nodepath + unc.substring( 
dfsReferral.path.length() );
        return "".equals( unc ) ? "\\" : unc;
       
        // tb
        // not working when calling listFiles() a second time:
        // original jCIFS 1.2.9:
        // String dunc = dfsReferral.nodepath + unc.substring( 
dfsReferral.path.length() );
        // return "".equals( dunc ) ? "\\" : dunc;
    }

Maybe the original is causing "unknown host" ?

bye,
Thomas
