Web Sockets

Hi

I am working on a project that will interact with some software called ROS (Robot Operating System). One of the development challenges we have is as follows:

ROS uses web sockets... So one connect with ws://localhost:9090 to the web socket server. It starts off as http, but then "upgrades" to web socket. It then keeps open this "tunnel" for bi-directional communication..

I need something like a HTTP Outbound adapter, but the Web Socket version of it...

Does anyone have any experience in this area?

Set httprequest=##class(%Net.HttpRequest).%New()
	Set httprequest.Server="www.intersystems.com"
	Do httprequest.Get("/")
	Do httprequest.HttpResponse.OutputToDevice()
	Do httprequest.Get("/cache/")
	Do httprequest.HttpResponse.OutputToDevice()

The above is the code which i found in this link http://docs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls?P...

Hello Community,

I recently encountered a issue with Caché and I can't figure out where the problem is coming from.

I noticed that the license limit (200) was reached whenever I was opening my Studio (so it seems). When this occurs, I restart Caché (with the Cube in the Taskbar), and the number of license used is back to 1%, but grows back after. The time taken before the number of license grows back again looks pretty random.

Here is a couple of screenshots :

We have an web application accessed using https, that uses CSP technology with frames.

The initial 'login' is via a single CSP page, which then redirects to another CSP page which creates the frames (4 in all) and loads a CSP page in each of those. For the most part the frames load without error, but sometimes when logging in and sometimes while using the system ' 5916 Illegal CSP Request ' errors occur.

I say 'login' in inverted commas as a Cache login is not performed just an application login, I don't know if that's relevant so thought I'd mention it.

I have an application that as part of the registration process is using reCaptcha to provide a captcha. The issue is that service is served from Google and is unavailable in certain countries, namely China. I've been researching this some and believe it's possible to proxy the requests to the Google CDN to avoid the Chinese firewall ban on Google URLs, however I'm not quite sure how to do this in CSP.


Does anyone have suggestions on how to solve this, either with a technical solution or an alternative service I can fall back to?
An example would be greatly appreciated.

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports. We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down. We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page. I am new to Cache so any help would be greatly appreciated.

Greetings!

I'm new to Zen reports and I'm wondering if what I'm trying to do is possible. I have a classmethod that accepts three parameters to generate an xml file from a global. I've set up my Report Definition to call the ClassMethod that generates the .xml file; however, I'm trying to figure out how to pass the parameters to that ClassMethod from the Report Definition. The example in the documentation shows parameter passing using SQL (which I'm not using), so I'm curious if this will work.

Hi,

We have a application developed in CSP and JS. Is there any way to make this application available in multiple language like Spanish etc.

We are ready to re-write the code in Zen also if it supports that feature.

Could any one of you please assist/advice a Solution to reach the required goal using Cache technologies, it will be a great help if someone has any sample code for the same.

Thanks

Paras

I was wondering if anyone has combined ZEN Web Development with frameworks such as W3Schools W3.CSS Framework or the popular Bootstrap Framework?

We are currently using Caché 2013.1.6 so we do not have ZEN Mojo installed which ships in Caché 2014.2 or later.

What would be the recommended approach if looking to integrate one of these frameworks?

I look forward to hearing your suggestions!

In my country we speak in spanish. My developing machine uses windows 8.1

I made a nice looking html mock-up using angular material (in Atom, writing in UTF-8). I just moved that mock-up to the CSP folder inside Ensemble and it shows the typical weird characters of character encoding problems.

Have you had an issue like this before?

My temporal solution for the html files: I just configured Atom to read the files in Windows 1252 encoding.

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?
