I would like to create a sftp session to download files with apache commons vfs2.
How do I do this?

I have my code as below. But the problem is manager.resolve keep opening a connection.
I would like to have a session for 5 minutes and close it when it's idle and reopen the session again when it's needed. Will this be possible?

public void download() 
 StandardFileSystemManager manager = new StandardFileSystemManager();
 FileSystemOptions fileSystemOptions = new FileSystemOptions();

 SftpFileSystemConfigBuilder.getInstance()
 .setStrictHostKeyChecking(fileSystemOptions, "no");
 SftpFileSystemConfigBuilder.getInstance()
 .setUserDirIsRoot(fileSystemOptions, true);
 SftpFileSystemConfigBuilder.getInstance()
 .setTimeout(fileSystemOptions, 10000);
 SftpFileSystemConfigBuilder.getInstance()
 .setPreferredAuthentications(fileSystemOptions, "password");

 try 
 manager.init();
 File f = new File("myfolder");
 final FileObject localFolder = manager.resolveFile(f.toURI());
 final FileObject remoteFile = manager.resolveFile(remoteURI, fileSystemOptions);

 localFolder.copyFrom(remoteFile, Selectors.SELECT_FILES);
 finally 
 manager.freeUnusedResources();
 manager.close();
