[SOLVED] Folder Watching

[jazz2k8]

Hi Folks,

I am having some files(.txt) in a directory called as Unprocessed folder,i would like to take one by one file and send it to the processing path say it as..C:\processingfolder
Each time when an UnprocessFolder get any new file it should be sent to the processing folder.

Any Idea....thanks in advance

Have u started with itatleast getting .txt files from a directory?
Rest would be next step, Do it step by step and in a simple way.

pick up the file

Does that mean moving the file from one directory to another?
One way would be to copy the file from one directory to the other and then deleting the file from the one directory.

Ur Right...it need to copy from the folder and send it to another path:cool:
If any new file comes into the Source folder it should be copied to the Dest Folder

Is this what u wanted?

public static void copy(File source, File dest) {
        try {
            BufferedReader br = new BufferedReader(new FileReader(source));
            BufferedWriter bw = new BufferedWriter(new FileWriter(dest)); 
            
            int read = 0;
            while((read = br.read()) != -1) {
                System.out.println((char)read);
                bw.write(read);
            }
            
            br.close();
            bw.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Check this link,
Java Programming [Archive] - Copy a file from another folder to specified folder

Here is the code

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class copyFiles {

	public static void copy(File source, File dest) {
	          
		File cpDestFile = null;
		try {
			if (dest.isDirectory()) {
				if (source.isFile()) {
					System.out.println("File name = " + source.getName());
					System.out.println("File name dest = " + dest.getPath());
					System.out.println("File name cpDestFile = "
							+ dest.getPath() + File.separator
							+ source.getName());
					cpDestFile = new File(dest.getPath() + File.separator
							+ source.getName());

				} else {
					System.out.println("Directory or File Not Found");
					return;
				}
			}
			BufferedReader br = new BufferedReader(new FileReader(source));
			BufferedWriter bw = new BufferedWriter(new FileWriter(cpDestFile));
			int read = 0;
			while ((read = br.read()) != -1) {
						bw.write(read);
			}
			br.close();
			bw.close();
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	public static void main(String args[]) {
		copyFiles fcpy = new copyFiles();
		File cpSrcFile = new File("D:\\Unprocessed_folder\\text1.txt");
		File cpDestDir = new File("D:\\processingfolder");
		fcpy.copy(cpSrcFile, cpDestDir);

	}
}

and check if any file has been created after a specific time which u need to store in some variable and compare it with file created time with the following code and then copy it into ur destination folder.

file = "C:\\yourFile.txt";
try 
{ //NOTE FILES MUST NOT HAVE SPACES IN THE NAMES OTHERWISE THIS DONT WORK!
Process ls_proc = Runtime.getRuntime().exec("cmd.exe /c dir " + getFilePath() + " /tc");
DataInputStream in = new DataInputStream(ls_proc.getInputStream());
for (int i = 0; i < 5; i++ )
{
in.readLine(); 
}
String stuff = in.readLine();
StringTokenizer st = new StringTokenizer(stuff);
String dateC = st.nextToken();
String timeC = st.nextToken();//TIME CREATED
in.close();
}
catch (IOException e1) 
{
System.out.println("Error in getting create time");
}
