Hi MIke,
As suggested by you, I have implemented *SIMPLE PROOF-OF-CONCEPT
*applications
which stream over separate and differently-named static channels within
the RDP session.
*STATIC VIRTUAL CHANNEL NAME* : vEcho
*PURPOSE *: Continuously sending data [ Hello ] from Remote to Local
Browser [ Guacamole Client ] and receiving same data [ Hello ] from Local
Browser [ Guacamole Client ] to Remote.
RESULT : *It stops sending data after few seconds* whereas It is working
fine in *mstsc and *other HTML5 solutions.
*Guacamole Client Implementation :*
client.onpipe = function(input_stream, mimetype, name) {
>
> if (name == "*vEcho*" ){
>
> var reader = new Guacamole.ArrayBufferReader(input_stream);
> reader.ondata = function(buffer) {
> var rdpdata = new Uint8Array(buffer);
> var b64encoded = btoa(String.fromCharCode.apply(null, rdpdata));
> console.log("Receiving Data :: Name of the Channel is : - ",name);
> console.log("Data is : - ",b64encoded);
> var output_stream = client.createPipeStream(mimetype, name);
> var writer = new Guacamole.ArrayBufferWriter(output_stream);
> console.log("Sending Data :: Name of the Channel is : - ",name);
> console.log("Data is : - ",rdpdata.buffer);
> *writer.sendData*(rdpdata.buffer);
> };

*Console Logs of the Browser are as follows :-*

*After that it fails sending and receiving data.*
Please find the attachment of Exe files* : * *Echo_EXE_files.zip [
contains 32-bit and 64-bit exe which has to be run on server side i.e.
Remote Server ] *
*DropBox Link to download the above ZIP file :
**https://www.dropbox.com/s/sgjcrn4sgcab481/Echo_EXE_files.zip?dl=0
<https://www.dropbox.com/s/sgjcrn4sgcab481/Echo_EXE_files.zip?dl=0>*
Please find the attachment of Echo Project files* : vEcho.zip [
contains the following files ]*
*DropBox Link to download the above ZIP file : *

<https://www.dropbox.com/s/sgjcrn4sgcab481/Echo_EXE_files.zip?dl=0>*
*1. Directory **Echo **-- Project Name*
*2. Echo.sln -- Main Solution file *
*3. Directory **Echo/Echo* *-- Server Side Module*
*4. Directory Echo/EchoClient --- Client Plugin*
*To view logs on Server-Side use debugview*
STEPS to reproduce issue are as follows :-
1. Download *Echo_EXE_files.zip* from the above link and Copy the exe
file in the Remote Server
2. Copy the below Javascript code and copy in guacamole.js
*Guacamole Client Implementation :*
client.onpipe = function(input_stream, mimetype, name) {
>
> if (name == "*vEcho*" ){
>
> var reader = new Guacamole.ArrayBufferReader(input_stream);
> reader.ondata = function(buffer) {

> console.log("Receiving Data :: Name of the Channel is : - ",name);
> console.log("Data is : - ",b64encoded);
> var output_stream = client.createPipeStream(mimetype, name);

> console.log("Data is : - ",rdpdata.buffer);
> *writer.sendData*(rdpdata.buffer);
> };
>
> }
>

3. Take the RDP of the Remote Server and run the exe file .
Please help me to resolve the above issue and let me know if I need to file
a bug or something in JIRA.
