Dear :
I created a lab. I am using sample code :
public class DemoServlet extends GuacamoleHTTPTunnelServlet {
private static final long serialVersionUID = 1L;
private final Logger logger = LoggerFactory.getLogger(DemoServlet.class);
public static SimpleGuacamoleTunnel tunnel = null;
@Override
protected GuacamoleTunnel doConnect(HttpServletRequest request) throws
GuacamoleException{
try {
if( tunnel == null) {
tunnel = inner();
}
return tunnel;
}catch(GuacamoleException e) {
logger.error(e.getMessage(), e);
throw e;
}catch(Exception e) {
logger.error(e.getMessage(), e);
throw e;
}
}
private static SimpleGuacamoleTunnel inner() throws GuacamoleException{
GuacamoleConfiguration config = new GuacamoleConfiguration();
config.setProtocol("rdp");
config.setParameter("hostname", "10.200.200.199");
config.setParameter("port", "3389");
config.setParameter("security", "nla");
config.setParameter("username", "admin");
config.setParameter("password", "P@ssw0rd");
config.setParameter("ignore-cert", "true");
config.setParameter("enable-drive", "true");
config.setParameter("drive-path", "/home/guacdshare");
config.setParameter("recording-path", "/anchor_dvr");
config.setParameter("create-recording-path", "true");
config.setParameter("recording-name", "test.guac");
InetGuacamoleSocket inet_socket = new InetGuacamoleSocket("10.200.200.200",
4822);
GuacamoleSocket socket = new ConfiguredGuacamoleSocket(inet_socket,config);
return new SimpleGuacamoleTunnel(socket);
}
}
It is ok. I can connet to target from browser.
Next, I try to extends【GuacamoleWebSocketTunnelEndpoint】
@ServerEndpoint ("/test_Tunnel")
public class DemoEndPoint extends GuacamoleWebSocketTunnelEndpoint {
@Override
protected GuacamoleTunnel createTunnel(Session arg0, EndpointConfig arg1)
throws GuacamoleException {
*GuacamoleConfiguration target_config =
Help.createGuacamoleConfiguration();*
* GuacamoleClientInformation browser_config = **Help*
*.createGuacamoleClientInformation();*
* GuacamoleSocket gua_server_socket = **Help**.createInetGuacamoleSocket();*
* ConfiguredGuacamoleSocket socket = new ConfiguredGuacamoleSocket(
gua_server_socket, target_config, browser_config);*
* GuacamoleTunnel tunnel = **Help**.assignGuacamoleTunnel(socket);*
* return tunnel;*
}
}
public class *Help*{
public static GuacamoleConfiguration *createGuacamoleConfiguration*(){
GuacamoleConfiguration config = new GuacamoleConfiguration();
config.setParameter("port", "3389");
config.setParameter("username", "admin");
config.setParameter("hostname", "10.200.200.199");
config.setParameter("ignore-cert", "true");
config.setParameter("security", "nla");
config.setParameter("password", "P@ssw0rd");
config.setProtocol("rdp");
return config;
}
public static GuacamoleClientInformation *createGuacamoleClientInformation*
(){
GuacamoleClientInformation info = new GuacamoleClientInformation();
info.setOptimalScreenWidth(800);
info.setOptimalScreenHeight(600);
info.setOptimalResolution(72);
return info;
}
public static InetGuacamoleSocket *createInetGuacamoleSocket*() throws
GuacamoleException{
return new InetGuacamoleSocket("10.200.200.200", 4822);
}
public static GuacamoleTunnel *assignGuacamoleTunnel*(final GuacamoleSocket
socket) {
return new AbstractGuacamoleTunnel() {
@Override
public GuacamoleSocket getSocket() {
return socket;
}
@Override
public UUID getUUID() {
return UUID.randomUUID();
}
};
}
}
But I get a error, So i add logger at [ *GuacamoleWebSocketTunnelEndpoint*]
@Override
@OnOpen
public void onOpen(final Session session, EndpointConfig config) {
logger.error("into onOpen");
try {
// Get tunnel
tunnel = createTunnel(session, config);

GuacamoleStatus.RESOURCE_NOT_FOUND);
return;
}
}
catch (GuacamoleException e) {
logger.error("Creation of WebSocket tunnel to guacd failed:

logger.debug("Error connecting WebSocket tunnel.", e);
closeConnection(session, e.getStatus());
return;
}
// Manually register message handler
session.addMessageHandler(new MessageHandler.Whole<String>() {
@Override
public void onMessage(String message) {
GuacamoleWebSocketTunnelEndpoint.this.onMessage(message);
}
});
// Prepare read transfer thread
Thread readThread = new Thread() {

private final RemoteEndpoint.Basic remote =
session.getBasicRemote();
@Override
public void run() {
logger.error("into run");
StringBuilder buffer = new StringBuilder(BUFFER_SIZE);
GuacamoleReader reader = tunnel.acquireReader();
char[] readMessage;
try {
logger.error("point 1");
String text = null;

logger.error("point 1---- a");
String uuid = tunnel.getUUID().toString();
logger.error("point 1---- b");
String code = GuacamoleTunnel.INTERNAL_DATA_OPCODE;
logger.error("point 1---- c");
GuacamoleInstruction lab = new

logger.error("point 1---- d");
text = lab.toString();
logger.error("point 1---- e");
}
logger.error("remote class : {}", remote.getClass());
logger.error("text : {}", text);

buffer.append(readMessage);
// Flush if we expect to wait or buffer is

if (!reader.available() || buffer.length() >=

remote.sendText(buffer.toString());
buffer.setLength(0);
}
}
logger.error("point 4");
// No more data
closeConnection(session, GuacamoleStatus.SUCCESS);
logger.error("point 5");
}
// Catch any thrown guacamole exception and attempt
// to pass within the WebSocket connection, logging
// each error appropriately.
catch (GuacamoleClientException e) {
logger.error("WebSocket connection terminated: {}",
e.getMessage());
logger.error("WebSocket connection terminated due
to client error.", e);
closeConnection(session, e.getStatus());
}
catch (GuacamoleConnectionClosedException e) {
logger.error("Connection to guacd closed.", e);
closeConnection(session, GuacamoleStatus.SUCCESS);
}
catch (GuacamoleException e) {
logger.error("Connection to guacd terminated
abnormally: {}", e.getMessage());
logger.error("Internal error during connection to
guacd.", e);
closeConnection(session, e.getStatus());
}
logger.error("point 6");
}
catch (IOException e) {
logger.error("I/O error prevents further reads.", e);
closeConnection(session, GuacamoleStatus.SERVER_ERROR);
}catch (Exception e) {
logger.error(e.getMessage(), e);
closeConnection(session, GuacamoleStatus.SERVER_ERROR);
}finally {
logger.error("out run");
}
}
};
readThread.start();
}
