Package com.ibm.jtopenlite.file Description

Provides classes to access IFS files on an IBM i host.

The FileConnection class is used to establish a connection to the file server. A FileHandle is used in conjunction with a connection to read and write the file. The following is a simple example of a program to create, read, and delete a file on the server.

import com.ibm.jtopenlite.file.*;

public class AccessIfsFile {
        public static void main(String args[]) {
                try {
                        String system = args[0];
                        String userid = args[1];
                        String password = args[2];
                        String filename = args[3];
                        FileConnection connection = FileConnection.getConnection(system,
                                        userid, password);

                        FileHandle fhWrite = FileHandle.createEmptyHandle();

                        connection.openFile(filename, fhWrite);
                        byte[] stuff = "Hello world".getBytes("UTF-8");
                        connection.writeFile(fhWrite, stuff, 0, stuff.length, true);
                        connection.closeFile(fhWrite);

                        FileHandle fhRead = FileHandle.createEmptyHandle();
                        connection.openFile(filename, fhRead);
                        byte[] buffer = new byte[100];
                        int bytesRead = connection.readFile(fhRead, buffer, 0,
                                        buffer.length);
                        connection.closeFile(fhRead);

                        String output = new String(buffer, 0, bytesRead, "UTF-8");

                        System.out.println("Read '" + output + "' from the file "
                                        + filename);

                        connection.deleteFile(filename);

                        System.out.println("File " + filename + " has been deleted");
                } catch (Exception e) {
                        e.printStackTrace();
                }
        }
