Copying Files in Java

How can I code in Java the copying of a file from one directory to another. I am trying to copy a Database from one folder to another and I do not want to use streams because this will read in characters or bytes but the Database is made up of tables. I thought there might be a method called 'copy' in the Java API, but I cannot find it anywhere.
The closest I have got to the solution is the use of renameTo method in the Java API. However this copies the file but also removes it from the original location (like cut and paste). Is there a way of using a method similar to that so I get the file in both locations?
Thanks in advance.

Here's a utility class I wrote specifically for that purpose. It contains a method for copying files, and one for copying entire directories(including sub-directories).
I use this mostly to move around mySql databases.
http://www.auburn.edu/~bradfje/FileUtil.txt
1. copyDirectory(String source, String destination)
source is the directory to be copied, destination is what you want the new diretory to be called. Use absolute file names.
2.copyFile(String source, String destination)
same remarks as above.

i copy a picture from one location to another using FileInpustStream method..
is there any better way to copy file faster, cause using this way takes way to much time to copy a picture file
          try

I need help with copying files in java?

hi, i use the following code sample to copy a directory structure and its files.
It copy's the directory-structure, but all the files in it have 0kb as size. except one file.
Here's the code:
public static void copyDir(String source, String target)
String [] listing = new String [0];
FileReader in = null;
FileWriter out = null;
String sourcePath = source;
String targetPath = target;
// Maakt directory onder target directory
File f = new File(targetPath);
f.mkdir();
// Maakt filelist van bestanden in source-directory
f = new File(sourcePath);
listing = f.list();
for(int i = 0; i < listing.length; i++)
f = new File(sourcePath + listing);
if(f.isDirectory())
copyDir(source + listing[i] + File.separatorChar,
target + listing[i] + File.separatorChar);
else
try
in = new FileReader(sourcePath + listing[i]);
out = new FileWriter(targetPath + listing[i]);
int t;
while (-1 != (t = in.read()))
out.write(t);
try { Thread.sleep(200); } catch (InterruptedException e) { }
System.out.println("Copied: " + sourcePath + listing[i]);
catch (Exception e)
System.out.println(e);

Here is a quick copy program that works. You'll need to deal with the exception instead of just throwing it though.
import java.io.*;
public class Copy
private static void copy(String source, String target) throws IOException
    // Create directory
    File file=new File(target);
    file.mkdirs();
    // Get contents
    file=new File(source);
    File[] files=file.listFiles();
    // Copy files
    int length;
    byte[] buffer=new byte[1024];
    for(int i=0; i<files.length; i++)
      String destination=target+File.separator+files[ i ].getName();
      if(files[ i ].isDirectory())
        copy(files[ i ].getPath(), destination);
      else
        FileInputStream in=new FileInputStream(files[ i ]);
        FileOutputStream out=new FileOutputStream(destination);
        while((length=in.read(buffer))!=-1)
          out.write(buffer, 0, length);
        in.close();
        out.close();
public static void main(String[] args) throws IOException
    copy(args[0], args[1]);

IMPORTANT. copying files in java

i would like to know how do i copy a file form one dir to another or do i have to just read from one file and write it to the other?? thanks for all the help

look at the "java.nio.*" package:

Best way to find and copy files

If i have a list of 2000 file names and want to find:
if they exist in folder x
then copy to folder y
else
output an error messege to txt file.
What would the most efficient way to do this be? So far i've used listFiles() and put a >HUGE< directory listing into an Array. Then I did a comparison for each file name in the list against the array. I know this cant be the most efficient way. I posted earlier in the board but for some reason NO one answered. Can anyone suggest and easier way to do this? and what is the best way to copy files in java? opening a bufferwriter etc? Essectially, im doing a restore from multiple backup directories to the original directory. Please help me if you can take the time.
Thank you,
jon

If i have a list of 2000 file names and want to
find:
if they exist in folder x
then copy to folder y
else
output an error messege to txt file.
What would the most efficient way to do this be?In a loop just read and write each file. If it does not exist, print an error.
So far i've used listFiles() and put a >HUGE< directory listing into an Array. A directory with a million entries is a HUGE directory, I guess you only have a few thousand.
I wouldn't bother reading the files into memory, you only need 2000 of them.
Then I did a comparison for each file name in the list against the array. The OS will do this for you when you try to open the file, which you will have to do anyway to copy it.
I know this cant be the most efficient way. More efficient way, don't do it at all.
I posted earlier in the board but for some reason NO one answered. Perhaps the problem seemed too obvious.
Can anyone suggest and easier way to do this?
and what is the best way to copy files in java? Copy one at a time.
opening a bufferwriter etc? Read a block of say 64K at a time. No buffers required.
Essectially, im
doing a restore from multiple backup directories to
the original directory. Please help me if you can
take the time.If you are recovering from a backup, the most important thing is ensuring the data is correct and valid, speed is less important. (It is no good if it is fast but corrupt)
Coping 2000 files is going to be only as fast as your drive(s) can handle. How you copy the file is less important.

How to copy a file from Java code

I have written a file through Java code in folder, say, "A". Now, I want a copy of that file exactly the same in some other folder "B". How, it can be done?

File copy/move thru java

Hi,
My code is something like this..
Which is trying to copy or move a file from one location to other.
Problem is I do not see the last modified date getting preserved,
in the copied file.
Why does this happen ? and how to preserve the last modified date
to copied file ?
File fTempRead = new File(fFrom.getAbsolutePath(), filename);
File fTempWrite = new File(fTo.getAbsolutePath(), filename);
if (fTempRead.canRead()) {
            lastmodified = fTempRead.lastModified();
            fTempWrite.setLastModified(lastmodified);
            RandomAccessFile randomWrite = new RandomAccessFile(fTempWrite, Messages.getString("FileIOHandler.14")); //$NON-NLS-1$
                FileChannel fWriteChannel = randomWrite.getChannel();
                RandomAccessFile randomRead = new RandomAccessFile(fTempRead, Messages.getString("FileIOHandler.15")); //$NON-NLS-1$
                FileChannel fReadChannel = randomRead.getChannel();
                FileLock readLock = fReadChannel.lock(0,fTempRead.length(), false);
                FileLock writeLock = fWriteChannel.lock(0, fTempWrite.length(), false);
                long fLength = 0l;
                byte by[] = new byte[1024];
                int byteread = 0;
                while ((byteread = randomRead.read(by)) != -1)     {
                    randomWrite.write(by, 0, byteread);
                readLock.release();
                writeLock.release();
                randomRead.close();
                randomWrite.close();
                if(move) {
                    boolean r = fTempRead.delete();
                if(!r) {
                    throw new FileMoveException(sb.toString());
        }

I'm not sure, but I would imagine that if you first setLastModified, and then write the file, the lastModified will be set again by the write.
Try calling setLastModified after you're done writing. (Not sure if you need to do it before or after close(). Try it each way.)

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

You were right. It was a permissions issue:

How to copy file from one location to another

Hi,
I am new to java, I tried the following code to move the file from one location to another
public class CopyFiles {
public String copy ( File source, File target)
throws IOException {
FileChannel sourceChannel = null;
FileChannel targetChannel =null;
try {
sourceChannel =new FileInputStream(source).getChannel();
targetChannel= new FileOutputStream(target).getChannel();
targetChannel.transferFrom(sourceChannel, 0,
sourceChannel.size());
finally {
targetChannel.close();
sourceChannel.close();
return "Success";
public static void main(String [] args) throws Exception{
File source = new File("C:\\users\\download.pdf");
File destinationFile = new File("C:\\apple\\download.pdf");
copy(source, destinationFile);
The above code is working perfectly, but I Don't want to include the file name in destination file. i.e. File destinationFile=new File("C:\\apple"), and at the same time the pdf with same name has to get stored in the destination location, how can I achieve this.

Yes?
If that's the case, then break the original up into separate directory and file name portions, and then construct the destination path from the destination directory plus original file name. You can do that by manipulating the full path string, or by using the methods in java.io.File.

Copy file from a location to another

I work on a Java process that must be optimized and I have some questions.
This process includes a part of copying a file from a location from another (to be more specific, all files that exist in a directory, to copy in another directory), wich technique is more efficient and quickly? To copy using FileInputStream/FileOutputStream in Java or using a java Runtime process that calls a copy command of the Operating System?

/* Note: Proper resource closing and exception handling is not done here */
try {
        // Create channel on the source
        FileChannel srcChannel = new
        FileInputStream("srcFilename").getChannel();
        // Create channel on the destination
        FileChannel dstChannel = new
        FileOutputStream("dstFilename").getChannel();
        // Copy file contents from source to destination
        dstChannel.transferFrom(srcChannel, 0, srcChannel.size());
        // Close the channels
        srcChannel.close();
        dstChannel.close();
    } catch (IOException e) {
    }Spawning a Runtime process is probably the least efficient way to do it.

hello!
I have developpe an animation with flash. before give it to othe person in order to use it, i would like to secure it by integrated a security module inside the software.Secure it from what? Being played? Copied? Deleted? Modified?
Because, i am a java developper, i have choose Netbeans 6.1 to secure it.That has to be the most random thing I've read in some time.
do you know how can i do to integrate my animation .swf inside my java class?Java can't play SWF files and Flash can't handle Java classes, so what you're suggesting here doesn't make a lot of sense.

How do I Copy files from one directory to another?

I know how to move files using the renameTo() method of File class, but is there a simple way to copy files, without the need of reading the input stream form one file and writing to a new one?

public static void copyFiles(File src, File dest) throws IOException

fout = new FileOutputStream (dest);If it's a directory, where in your code are you appending the source file name to the path, before trying to open an output stream on it? You're not.
BTW, this is awful:
catch (IOException e)
IOException wrapper = new IOException("copyFiles: Unable to copy file: " +
src.getAbsolutePath() + "to" + dest.getAbsolutePath()+".");
wrapper.initCause(e);
wrapper.setStackTrace(e.getStackTrace());
throw wrapper;
}1) You're hiding the original IOException and replacing it with your own? For what good purpose?
2) Even if you had a good reason to do that, this would be simpler and better:
throw new IOException("your custom message goes here", e);
rather than explicitly invokign initCause and setStackTrace. Yuck!

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.
