Scenario :
A J2ee based ERP application hosted in Amazon EC2 cloud
Clients use web browsers (Firefox/Chrome) to access application
Requirement :
Need to integrate POS terminal with client browser, read few card information and auto populate the payment related fields while billing
Question :
Is it Feasible in anyway (JS?, Applet?, Plugins?) to integrate to POS terminal with a browser
If Yes, Can I get some pointers to start the research?
I have googled and could not find any thing related to my problem.
Device is POS Machine - Verifone VX520
Thanks

I`m totally new to Bloomberg and using Bloomberg api in python/flask
I tried to read all the documentation provided by the windows SDK
I understand that DAPI is only for local applications using localhost and default port
but actually I am confused about the usage of SAPI Installation and usage...
First:
after installing sapi on machine with bloomberg terminal and letting the sapi process up , I will write an application by python code that import blbapi and use the sapi
should this application be on the same machine , or it can be on another machine and give it the ip and port of the sapi process and should the other machine have bloomberg terminal too?
second:
what about the client side, any browser which open this application should the clients have bloomberg terminal too??
Excuse my naive question ..
Thanx in advance
Python application machine doesn't have to have a Bloomberg terminal installed. You will only need Bloomberg libraries installed (but not terminal) software.
You need to provide "ip of terminal pc" + "uuid" when making a connection to SAPI.
Also, the user/terminal must be logged in.
Check and be very careful with licensing. You can try asking your account manager.
Don't take this as licensing advice, but different exchanges and data sources can have different rules around the data so it depends what data you pulling. As I understand the data pulled by a user/script is for that specific terminal owner only.
Different terminal "owners" with the same access might not be allowed to see the data pulled by other scripts/users.
SAPI allows you to use BBG data off the machine where the user is logged in HOWEVER this data can not be viewed by anyone but the logged in user - for legal reasons rather than technical ones.
The typical use case for SAPI is there complicated calculatios (be it exotic pricing or realtime portfolio risk) is being performed that aren't practical on the desktop.
Be aware that all BBG data and calculations are tied to the user, the data can't be given to anyone else...
Apologies in advance for somewhat vague information. I am new to Citrix XenApp/XenDesktop technology and am just looking for generic troubleshooting information.
At my place of employment we have kiosks that are configured to connect to a SaaS webapp. These kiosk have either the Citrix XenApp or XenDesktop installed.
One of the icons launches the IE browser that connects to the SaaS app using a preconfigured user account. Sometimes, however, instead of launching the browser, the system displays the "The session limit has been reached. Please contact your system administrator." error shown in below image.
The people administering these kiosks think that this message comes from the SaaS web application but that application does not enforce any limits on how many session are open for a given account under a given time.
Also considering how Citrix XenApp/XenDesktop works I would think (but maybe I am wrong) that if the SaaS app did reject a user login, we would be displayed an error message in Internet Explorer instead of this ICA prompt.
So I think that the issue here could be that the message is not about login sessions made to the background SaaS app but either about Citrix sessions or perhaps previous IE browsers somehow running in the background(?)
However our company's Citrix team looked at this and noticed that "Citrix was still active" when this prompt was displayed. The conclusion was then that Citrix is for that reason not the cause here.
So I wanted here to ask some questions on what things I could consider as causes and where I could look in the hopes of getting started on this issue.
This would be for XenApp / XenDesktop 7.18.
The questions I have:
Does XenApp / XenDesktop have log files that can be consulted for
debugging issues like this?
Is it possible to get XenApp / XenDesktop to run in debug mode (to
output more details to the log files)?
Does Citrix have configuration settings that could lead it to
have an issue like this?
A. First check the event logs and see when you facing this issue so does any event logs generated.
B. Also you can check the ICA configuration tool for session settings and checked if session settings are set to NEVER.
C. The ICA listener configuration tool is located at Start > All Programs > Citrix > Administration Tools > ICA Listener Configuration.
You are on the right track with the SaaS application itself reporting the error. If this Citrix session was already active when the icon was clicked again and the preconfigured user was already logged into the SaaS application, that would account for this error. To investigate, logout the Citrix session and try clicking the icon again, or check SaaS application to see if that preconfigured users is already connected.
Is the same user used for all these kiosks or is each kiosk supposed to have a unique user? Can this preconfigured user log in multiple times?
I’m facing a deployment issue for my product. I have to deploy it on a couple of servers which are located on different countries. My product has 3 main components:
Application server: server and database (I'm using MongoDb)
User app: communicates with application server
Web server
Every application server can working independently. The requirements are:
The web server can access to all Databases and treat them as 1 single database.
The data of Application server 1 must be stored on its own database (not on Application server 2, or 3, or so on).
After googling around, 1 solution is deploying sharded clusters. Because I’ve never done this before, so is it a good idea? Will it meet the requirements? What points that I have to pay attention to when doing this? If it is not a good idea, please show me a good way to solve the problem.
Thank you very much.
I'm building a hybrid app that speaks to a Bluemix app. I've got Mobile Application Security and Mobile Quality Assurance as a service. I'm using IBMLogger to send log messages, like so:
IBMBluemix.getLogger().info("Device successfully registered: "+ JSON.stringify(response));
I was under the impression that the MobileFirst-style services on Bluemix acted somewhat like the same components for a local MF install. I'm trying to find where I can see my log files in the BM console but have not been able to find them.
For a local MF install using the hybrid SDK, you have to specifically say you want your logs sent to the server, but I do not see that option when looking at the hybrid docs for BM/MF.
There is some doc here: https://www.ng.bluemix.net/docs/starters/mobile/mobilecloud/nodejsmobile.html#log
I suppose by default the log goes to the console, which you can retrieve through the loggregator, aka do cf logs <yourapp> --recent. You can also use the Monitoring & Analytics service to retain logs - see the above doc.
I'm evelauting using thie service. http://www.freegeoip.net/ & i quote the text below.
The freegeoip web server is free and open source so if the public service limit is a problem for you, download it and run your own instance
The public service limit of 10,000 queries per hour by default might or might not be a problem for me, so i just want to take the safe route early enough by downloading it and running my own instance.
However, i have zero experience on deploying such a server. Does any one here have or know of a walk-through that can get me started deploying my won instance. Can i host this server on windows or my own instance must be hosted on a linux server?
My site is hosted in IIS on windows.
