java as/400 ifs question

[tdavi1635]

Hi, all! Here's my question. There is a way to program
to copy a file from one directory to another on the AS/400 using the
installable file system classes(here's the ibm.s code folows)

My problem is that I need to copy files from NT network to as/400 ifs.
Please, give me some hints of how to use the existing code (this is my very
first java assignment)
//Thanks in advance and please, cc: your reply to my e-mail:

exit.

// Assume the first parameter is the system name,

system = parameters[0];
sourceName = parameters[1];
targetName = parameters[2];

try

// Create an AS400 object for the AS/400 system that holds the
files.

AS400 as400 = new AS400(system);

// Open the source file for exclusive access.

source = new IFSFileInputStream(as400,
sourceName,
IFSFileInputStream.SHARE_NONE);

System.out.println("Source file successfully opened");

// Open the target file for exclusive access.

targetName,

System.out.println("Target file successfully opened");

// Read the first 64K bytes from the source file.

int bytesRead = source.read(buffer);

// While there is data in the source file copy the data from
// the source file to the target file.

while (bytesRead > 0)

target.write(buffer, 0, bytesRead);
bytesRead = source.read(buffer);

source.close();
