I'm receiving a JSON payload via a REST API, I'd like to %JSONImport this stream into a class which extends %JSON.Adaptor. The problem is that the JSON is an array whose elements have no key (as you can see in the example JSON below). Right now I'm having to do some manipulations to convert the stream into a dynamic object and do a %Set which inserts a made up key "record" so "thingone" and "thingtwo" have an associated key that I can use when referencing "thingone" and "thingtwo".such as record.

How do we trigger a BPL Business Process on a time schedule?

We are building a production that takes a steady stream of (HL7) lab results messages, processes them and stores them in a temporary database table. At scheduled points during the day (eg 0800, 1300, 1600) the database is queried and messages sent on to the downstream system. Aiming that the Processes to be implemented in BPL if possible - but we are having trouble triggering code in a BPL as a scheduled job.

I want to call the REST endpoint and return the list of objects. I`ve created the method but it displays an error: 
<METHOD DOES NOT EXIST>GetAllPersons+10^Lab3.RestClient.1 *Count,%ZEN.proxyObject

Here is an example of a rest call via ARC:

Not sure if  %ConvertJSONToObject is used properly but I did not find another

I am trying to run the CSP server. But I get the error:

It worked once, but when I made some changes is displayed an error.
Also, a WEB page looks like this:

Did you face this issue? What is the reason for it?

I need to create a simple REST application.
I`ve created an app:

Also here is a dispatcher class:
 

ClassExtends%CSP.REST0

But when I call the Get method: http://localhost:52773/csp/crud/hello
There is an error: 403 Forbidden
I don't understand what can cause it.

Welcome everybody!

In this short article I would like to present an example of use that surely many of you who work with IRIS as the backend for your web applications have faced on more than one occasion and it is how to send a file to your server from the frontend.

Generally the simplest way I have found to perform this task is to transform the file from the frontend to the Base64 format and make a POST call to our server attaching the Base64 obtained to a JSON message in which I indicate in a parameter the name of the file and in another the encoded data.

I am attempting to setup my first OAuth2 client, as we are adventuring into the realm of making FHIR API calls to our EMR from HealthShare Health Connect. 

I have gone through and set up the Issuer Endpoint, and Client Configuration but now I want to test it and verify that the setup is correct. When I setup the Client Configuration, it would not allow me to use Discovery as it was saying I needed a "Client secret" but was not given one. So I set it up manually, thinking I hit all the information correctly.

Hi Community, 

Can I please check if any one is aware of any functionality in HealthShare to verify NHS Number check digit.

We are trying to implement the NHS Number check digit validation using Modulus 11 Algorithm ( described here : NHS NUMBER (datadictionary.nhs.uk) ) 

I wanted to check if there is any built in option available or if anyone has implemented something similar using Object Script. 

Thank you for your help.

Anybody know if there is a ObjectScript kernel for Jupyter? Would be kinda interesting to testing scripts, etc. And since we kinda have the language runtime in the VSCode ObjectScript extension I wonder if that could be utilized fora  jupyter kernel?

Maven Projects mixing ObjectScript and Java

What is Maven?

Maven is a tool, hosted by the Apache Software Foundation, for building and managing any Java-based project. Apache Maven is the best source of information.

Why Maven?

Managing a project, its dependencies, and life cycle can be a tedious task. Maven automates these tasks, making project management much simpler. Maven also defines a standard directory layout and provides tools for initializing projects. These tools employ project templates called maven archetypes There is a rich library of archetypes available.

Hi,

I'm receiving in one of our interface a XML file as a %Stream.GlobalBinary, and in the source Application that produces this XML file, the user sometimes add a special character that force the XML file to have the header encoding to UTF-8, instead of ISO-8859-1 : 
<?xml version="1.0" encoding="UTF8"?> 

When my current interface tries to convert the %Stream.GlobalBinary into  %XML.XPATH.Document to this exceptional UTF8 header encoding of the XML file : 

Set tSC=##class(%XML.XPATH.Document).CreateFromStream(stream,.

While creating my latest examples for the JavaContest I faced the need
to communicate with my code from a program in IRIS to my Java code.

Communication with |CPIPE| worked as READ or WRITE  but not both?
In the Documentation Named PIPEs are explained rather shortly.
"Once open, a pipe acts like an ordinary device."  Not so precise.
I failed to achieve my expected READ/WRITE  as TCP would offer. 

Has anyone a working example to demonstrate it? 
Any suggestion is welcome.

I found a workaround for my actual case.
Though I'm not so happy with it.

I have received 2 errors while publishing Patient data to repository. Message viewer displays like below and the Application log found  bold content.

Could you please help me on this to resolve the errors.

An error occurred with the web application.
It has been logged to system error log (System Operation>System Logs>Application Error Log).

"<METHOD DOES NOT EXIST>OnPage+42^EnsPortal.MessageContents.1 *%Id,HS.FHIRServer.API.Data.Request : CSP Error"

Business Operation Event logs displays "ERROR <Ens>ErrRequestNotHandled: Request message '3@HS.FHIRServer.API.Data.

Based on the successful solution for my 2nd contribution to the Contest 
I used an adapted version for this package. And have some findings I'd like to share.

Multiple communication steps over CPIPE may take time.
You won't recognize it on a fast machine. But a slower box with
Windows + Docker Desktop + your browser (and more) is neither
"Speedy Gonzales" nor a "Road Runner". 🙂

First observation you launch your OS command and see NO result
On the console, you just sit there and expect a reply.
Establishing the Connection to IRIS is a typical case.

Hi community members!

Recently a customer ask me about a problem that detected when they were trying to send a post call to an external HTTP service, this service has changed and now it redirects to another URL, so they have setted to true the FollowRedirect parameter (setted to false for POST calls by default), what is the problem? They are sending a custom header in the post call and after the redirection this value is deleted.

I've reviewed the code of %Net.

I wanted to provide a heads up of an improvement in how we generate and call method code in IRIS 2023.1.

A class in IRIS is composed of two main runtime components:

1. Class Descriptor - A highly optimized list of methods, properties, class parameters that make up the class along with attributes associated with each of these e.g. public/private setting.
2. ObjectScript code - A set of routines that contain the ObjectScript code to be executed when a method is called.

I was recently asked whether we have a function to convert LDAP date time stamps into $HOROLOG format or other formats and the answer is not at the moment, but there is a simple method to do the conversion.

Hi everyone, 

today I'm asking your help with an issue related to the response messages sent from my production to a client software, such as Postman or SoapUI. 

Issue

In the last few days I've been unable to view the responses received from my production in Postman, even if I was able to do so earlier. I'm sending the request to a remote server reachable via a Putty tunnel.

Postman Test

I'm currently testing this simple POST message: 

{
  "name""John Doe"

Hi folks,

I have published a new package on OEX.

In short, it is a string datatype that support various configuration options and flexibility.

Business Case

1. You have some library classes and other reusable structures that you use across systems.
2. You have a "multi-tenant" environment where one code base is shared amongst tenants, which each have their own namespaces configured.
   1. Specific rules and business processes are stored in that tenant's namespace.
   2. The core class structures are the same.

Here in %SYS, we have already examined users, resources, and roles. Now that we know how to set all of that up, we should give it a purpose. Next we will talk about applications! As you may expect, we will see various identical class methods defined here that we have seen in the previous classes. However, some of them will have some tiny yet significant differences.

This applies to embedded and dynamic SQL queries in Caché ObjectScript. If I attempt to terminate the process via Management Portal, nothing happens. Neither does Ctrl C nor closing the terminal window in which my program is running, nor setting a stop flag in a global which is read by the program on each loop iteration. The only way to stop the query appears to be restarting the Caché server (which is running locally on my PC).

I am making a POST request to an API. In the case of an error, I don't know what parameters the response JSON will contain (they will change depending on the error). I am converting the response stream to an object but then I need a way to loop through all the properties and access their values. The following code is making the POST request, reading the response, and trying to add all the error messages to an array. But I can't iterate over the properties of the tProxy.errors object because it is a %ZEN.proxyObject. Is there a better way to do this?

Set tSC=..Adapter.Post(.tHttpResponse, , tPayload)
Set msgData = tHttpResponse.Data.Read()
Set temp = ..JSONStreamToObject(msgData, .tProxy)

If (tProxy.errors '= "") {
    Set errMsgs = ##class(%ListOfDataTypes).%New()
    Set itr = tProxy.errors.%GetIterator()
    While itr.%GetNext(.key,.val) {
        Do errMsgs.Insert(val)
    }
}
