From source file:com.learningobjects.community.abgm.logic.ControllerJob.java

private void download(String sourceUrl, File destinationFile) throws IOException {
    logger.log(Level.INFO, "Downloading or copying file from " + sourceUrl + " to " + destinationFile);
    FileObject sourceFileObject = null;
    OutputStream outputStream = null;
    try {//  w ww . ja  v  a 2 s  .  c  om
        // special case sftp so that new hosts work out of the box. other options could go here too
        SftpFileSystemConfigBuilder sftpFileSystemConfigBuilder = SftpFileSystemConfigBuilder.getInstance();
        FileSystemOptions fileSystemOptions = new FileSystemOptions();
        sftpFileSystemConfigBuilder.setStrictHostKeyChecking(fileSystemOptions, "no");
        // actually try to get the file
        FileSystemManager fsManager = VFS.getManager();
        sourceFileObject = fsManager.resolveFile(sourceUrl, fileSystemOptions);
        FileContent sourceFileContent = sourceFileObject.getContent();
        InputStream inputStream = sourceFileContent.getInputStream();
        outputStream = new FileOutputStream(destinationFile);
        // do the copy - this is probably a dupe of commons io, and many others
        byte[] buffer = new byte[8192];
        int length;
        while ((length = inputStream.read(buffer)) > 0) {
            outputStream.write(buffer, 0, length);
        }
    } finally {
        if (outputStream != null) {
            outputStream.close();
        }
        if (sourceFileObject != null) {
            sourceFileObject.close(); // this will close the fileContent object, too
        }
    }
