How to transfer a file to sftp using jsch using base64 encoding

I am encoding my file into a base64 string. I want to transfer this to a sftp folder using JSch without creating a local file. How can I do that?

I Used put(String src, String dst) method in ChannelSftp class

private void getConnection(String username, String hostname, String password) {
    JSch jsch = new JSch();
    java.util.Properties config = new java.util.Properties();
    config.put("StrictHostKeyChecking", "no");
    try {
        session = jsch.getSession(username, hostname, 22);
        session.setConfig(config);
        session.setPassword(password);
        session.connect();
        channel = session.openChannel(CHANNEL_TYPE);
        channel.connect();
    } catch (JSchException e) {
        e.printStackTrace();
    }
}

private void disconnectConnections() {
    if (channel.isConnected()) {
        channel.disconnect();
    }
    if (session.isConnected()) {
        session.disconnect();
    }
}

private String getConfiguration(String key) {
    return configuration.getString(key);
}

public void uploadToSftp(String sftpFileLocation, String fileToBeUploaded, String filename) {
    if (session == null || channel == null || !session.isConnected() || !channel.isConnected()) {
        getConnection(getConfiguration(USERNAME), getConfiguration(HOST), getConfiguration(PASSWORD));
    }
    try {
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd(sftpFileLocation);
        byte[] data = BaseEncoding.base64().decode(fileToBeUploaded);
        InputStream is = new ByteArrayInputStream(data);
        channelSftp.put(is, filename);
        disconnectConnections();
    } catch (SftpException e) {
        e.printStackTrace();
    }
}

You would probably use the method

void put(InputStream src, String dst, SftpProgressMonitor monitor, int mode)

in class ChannelSftp. JSch also provides an example on how to set up and tear down an SFTP session.
