Is there a Sabre GDS Connector api in java available to connect and send the commands to Sabre GDS and get the response? I need to automate the sabre commands output
If you have access to the sabre web services, the SabreCommandLLSRQ web service can be used to send commands within a sabre session.

We have an Azure Function supporting a SignalR hub leveraging Azure SignalR Services to publish messages to connected signalR clients. We'd like to enable MessagePack protocol in the function but we could not find any documentation or guidelines to tell how to do it. Any ideas on how to approach this problem?
Interestingly Message Pack protocol is initiated and used when the client app negotiates with the function. Further information can be found here.
I have an ASP.NET Core MVC application, that i want to connect it to POS ( Point of sale) device, and send payable price to pos and then pos send back me the result.
I want to run these operations on client system. how can i send data to ports of client system?
Before I had the same problem. your web application can't communicate with the port directly.
To do that you have to do the following :
1-Create a windows service project
2-Host a web Api in windows service (Web API Self-Hosting Using Windows Service)
That way your web application can call web api hosted in windows service, because web api is listening to the incoming requests. in web api, you can communicate with your desired port directly and send the result to the client.
Finally, to use this feature in your web application you have to prepare a batch file(it runs your windows service) of your windows service project and put it in the download section of your website.
if any user wants to use POS( Point of sale) device have to install the bat file
How does OpenStack Horizon communicate with OpenStack? Is it through the OpenStack REST API only? Or is it through function calls?
http://docs.openstack.org/developer/horizon/
OpenStack services can only be visited via REST API IIUC. Horizon can be installed in a dedicate node which isolated with other services.
Even there are some command line tools, but they are provided for cloud administrators and developers (they can only be invoked locally), not for normal users.
It only communicates using RESTful calls, and mostly on HTTP (Non-Secure).
Every major service in OpenStack has an API service as endpoint for clients to access, eg. openstack-nova-api, openstack-glance-api etc. But for every major service, there are other minor services like openstack-nova-scheduler, openstack-nova-conductor etc. these services are suggested to be deployed on other nodes rather the node where API service is running to get some kind of isolation.
My question is how openstack-nova-api knows where the real services(openstack-nova-scheduler/openstack-nova-conductor) are running, how they communicate with other? When openstack-nova-api got a new request, how does it distribute it to the real services which can process and send back the results?
Internal communication between OpenStack modules is done through the AMQP message queue, typically managed by RabbitMQ.
Here is what I am trying to do:
Pick up files from various locations using BizTalk
Debatch the data
Publish a message to NService bus.
The question is how to publish a message to NSB when the underlying transport for NSB is SqlServer and not MSMQ?
Have you considered exposing a Service in NServiceBus as a WCF endpoint? You can then call the WCF endpoint from Biztalk.
