Mount

PasswordCredentials cr = new PasswordCredentials(

                 “userName ”,“ password ”, “domain ”);

// Create a new Mount Point

Mount mt = new Mount(“ IpAddress”,  “ShareName ”, cr);

// Close all connections and mount points

Client.stop();

Open, read, write and delete file

PasswordCredentials cr = new PasswordCredentials(

                 “ userName ”,“password ” ,“ domain ” );

// Create a new Mount Point

Mount mt = new Mount(“IpAddress ”,“ShareName ”, cr);

Params pr = new File.Params(File.ACCESS_WRITE, File.SHARE_FULL,

File.DISPOSITION_OPEN, false);

File file = new File(mt, “ text.txt ”, pr);

Buffer buff = new Buffer(DATASIZE);

// read DATASIZE from the begginig of the file.

file.read(buff);

// write the buff from the offset DATASIZE.

file.write(buff);

// mark the file for delete.

file.deleteOnClose();

// close the file.

file.close();

// close the mount point

mt.close();

Delete file by name

PasswordCredentials cr = new PasswordCredentials(

“userName ”, “password ”,“domain ”);

// Create a new Mount Point

Mount mt = new Mount(“IpAddress ”,“ShareName ”, cr);

File.delete(mt, “text.txt ”);

// close the mount point

mt.close();

Browsing directory

PasswordCredentials cr = new PasswordCredentials(

“userName ”,“password ” ,“domain ”);

// Create a new Mount Point

Mount mt = new Mount(“ ”IpAddress,“ShareName ”, cr);

Directory dir = new Directory(mt,“dir1 ”);

Directory.Entry entry;

System.out.println(DIR + “scan: ”);

do {

entry = dir.next();

if (null != entry)

System.out.println(entry.name + “: size = ” + entry.info.eof);

} while (entry != null);

// close the directory browsing.

dir.close();

// close the mount point

mt.close();

Access via Streaming

PasswordCredentials cr = new PasswordCredentials(

“ userName ”, “password ”, “domain ”);

// Create a new Mount Point

Mount mt = new Mount(“IpAddress ”,“ShareName ”, cr);

// create a new file.

File.Params fileParams = new File.Params(

File.ACCESS_READ | File.ACCESS_WRITE |

File.ACCESS_DELETE, File.SHARE_FULL,

File.DISPOSITION_OPEN_IF, false);

File file = new File(mt, “myCreatedFile.txt ”, fileParams);

// create output stream

OutputStream outputStream = new SmbOutputStream(file);

// create some data to write

int totalAmountOfData = 1024 * 1024 * 10;

byte [] data = createByteBuffer( totalAmountOfData);

// write all the bytes — buffering is done by TCP networking code

outputStream.write(data);

// alternative way of writing all the bytes with a little more control

int amountToWriteEachTime = 1024 * 1024;

int currentPosition = 0;

while (currentPosition < data.length) {

file.setPosition( currentPosition);

outputStream.write(data, currentPosition, amountToWriteEachTime);

currentPosition += amountToWriteEachTime;

}

// close the stream

outputStream.close()

// close the mount point

mt.close();

Enumerate the shares available

Iterator iterator = Network.enumerateShares(smbServer, credentials);

while (iterator.hasNext()) {

Share.Info shareInfo = (Share.Info) iterator.next();

System.out.println(“share name = ”+ shareInfo.name);

}

Enumerate the servers available

iterator = Network.enumerateServers(domain, credentials);

while (iterator.hasNext()) {

String serverInfo = (String) iterator.next();

System.out.println(“ server name = ” + serverInfo);

}
