Description

 
I am using the below class to transfer a file from one folder to another on a server I am using commons-vfs-2.0 jar. :

import org.apache.commons.vfs.FileObject;

import org.apache.commons.vfs.FileSystemException;

import org.apache.commons.vfs.FileSystemOptions;

import org.apache.commons.vfs.Selectors;

import org.apache.commons.vfs.impl.StandardFileSystemManager;

import org.apache.commons.vfs.provider.sftp.SftpFileSystemConfigBuilder;

public class SFTPTest {

public static void main(String args[]) {

try

{ String ftpUrlSrc = "sftp.host.address" + ":" + "8022" + "/SRC_FOLDER"; String sftpUriSrc = "sftp://" + "sftpUser" + ":" + "pass$123" + "@" + ftpUrlSrc; String ftpUrlDest = "sftp.host.address" + ":" + "8022" + "/DEST_FOLDER"; String sftpUriDest = "sftp://" + "sftpUser" + ":" + "pass$123" + "@" + ftpUrlDest; StandardFileSystemManager manager = new StandardFileSystemManager(); FileSystemOptions opts = new FileSystemOptions(); SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(opts, "no"); manager.init(); FileObject fileObjectSrc = manager.resolveFile(sftpUriSrc + "/" + "trial_file.tar.gz", opts); FileObject fileObjectDest = manager.resolveFile(sftpUriDest + "/" + "trial_file.tar.gz", opts); fileObjectDest.copyFrom(fileObjectSrc, Selectors.SELECT_SELF); //The below moveTo() call works without any issue. fileObjectSrc.moveTo(fileObjectDest); }

catch (FileSystemException e)

{ // TODO Auto-generated catch block e.printStackTrace(); }

}

}

The below exception is being thrown:

 org.apache.commons.vfs.FileSystemException: Could not copy "sftp://sftpUser:**@sftp.host.address:8022/SRC_FOLDER/trial_file.tar.gz" to "sftp://sftpUser:*@sftp.host.address:8022/DEST_FOLDER/trial_file.tar.gz". at org.apache.commons.vfs.provider.AbstractFileObject.copyFrom(AbstractFileObject.java:1032) at SFTPTest.main(SFTPTest.java:27)
