I have a process that takes data from a CSV file (actually a record mapper object) and creates a nicely formatted JSON string I would love to send this along to a RESTful business operation.  However no matter what I try, I continually get <INVALID OREF> errors when trying to populate the object that extends Ens.Request to give it the JSON string.

I can add strings, other objects, you name it - but stuffing a JSON formatted variable/object into another object I want to send someplace is proving to be an impossibility.

Does anyone have an example of sending an Ens.Request or other object (not an HTTPRequest object - but some other custom object) containing a JSON string to an Operation where the operation ultimately pulls the JSON from the object that was sent to it, makes the REST POST call and sends the response back

I'm using callin to get global values.

Here's a simple function to get string value from global and return it:

int GetGlobalStr(char *global, CACHE_EXSTRP result)
{
    int push = CACHEPUSHGLOBAL(strlen(global), global);

    // narg Number of subscript expressions pushed onto the argument stack.
    int narg = 0;

    // flag - Indicates behavior when global reference is undefined:
    // 0 — returns CACHE_ERUNDEF
    // 1 — returns CACHE_SUCCESS but the return value is an empty string.
    int flag = 1;

    int get = CACHEGLOBALGET(narg, flag);

    int pop = CACHEPOPEXSTR(result);

    return ZF_SUCCESS;
}

I get global value in result successfully. However I need to iterate over $lb. How can I do that?

I am still new to cache objectscript and am trying to figure out how I would go about removing the escape characters from my JSON below. When I call the $toJSON method it's adding the "\" character in the file path.

 

{"FileStatus":"P","Path":"\/somepath\/test\/test123\/filename.txt","InterchangeOID":"100458"}

So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.   

There's only one problem:  You've never used Angular, and don't know how to make it talk to Caché.

This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.  

Part 1 - Setup

To start fresh, we will create a Namespace for our new application - WIDGETDIRECT, and set this up with Code and Data databases, and appropriate Security roles.  

Our next step is to set up 2 Applications to serve web content; one for the Angular web content and one to serve the REST conten

Has anyone tried the new Activity Volume Statistics and Monitoring  in Ensembel 2016.1? I would love to get some feedback.

If you haven't read about this, there is a dashboard that provides counts and response times for messages sent and received by each configuration item. Alternatively the underlying data is arranged in tables that should make it easy for you to use your favorite SQL reporting tools to generate reports for short term performance monitoring or longer term capacity planning.

The %Net.SSH.Session class lets you connect to servers using SSH. It's most commonly used with SFTP, especially in the FTP inbound and outbound adaptors.

In this article, I'm going to give a quick example of how to connect to an SSH server using the class, describe your options for authenticating, and how to debug when things go wrong.

Here's an example of making the connection:

Set SSH = ##class(%Net.SSH.Session).%New()
Set return=SSH.Connect("ftp.intersystems.com")​

This creates a new connection, and then connects to the ftp.intersystems.com SFTP server on the default port. At this point, the client and server have picked encryption algorithms and options, but no user has logged in yet.

Once you're connected, you can choose how to authenticate. There are three methods to choose from

Hello, our X12 File Service won't process files we encountered X12 files where they inserted CR LF after 80 bytes repeatedly in the middle of segments. X12 Parser does not seem to like it. I see there is a Whitespace property in Adapter. I am not sure if it ignores white space in the middle of a segment. I also heard about TolerateNewLine setting but I believe this also does not tolerate New Lines in the middle of a segment. We will probably have to read the file, strip out any CR and LF, write to a new file that the X12 file service can process. If there is a better solution I would like to find out about it. Thanks

Dear team,

I am trying to experiment the Docker container in our development environment. I have successfully build an image and running the container. When I access the CSP portal home page ( http://<host-ip>:57772/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS), I am getting the following error:

I logged in to the running container (docker exec -it <container-id> sh), issued the command, 'ccontrol list' where the state says 'warn'

Hi,

I would like to use EnsLib.HL7.Operation.HTTPOperation for sending HL7 messages via HTTP. It sends the Content-Type as "text/html"

I would like to change it to something else, say "text/plain". I cannot see a way to do it.

I have now written a custom Operation (based on EnsLib.HTTP.OutboundAdapter) and modifying the Content-Type while POSTing using SendFormDataArray(). It's bit frustrating to parse the response etc.,

I would rather prefer to use HTTPOperation of HL7. Can somebody help?

Thanks.

Class ICT.Experiments.A Extends %Persistent
{
Property Name As %String;
Property Collection As list Of ICT.Experiments.B;
Property Collection2 As array Of ICT.Experiments.C;
}

Class ICT.Experiments.B Extends %Persistent
{
Property Name As %String;
}

Class ICT.Experiments.C Extends %Persistent
{
Property Name As %String;
}

I have the classes above and I can select columns from the array collection by using two joins as follows:

SELECT 
mainTable.ID, mainTable.Name, c.Name
FROM ICT_Experiments.A mainTable
LEFT JOIN ICT_Experiments.A_Collection2 arrayTable ON arrayTable.A = mainTable.%ID
LEFT JOIN ICT_Experiments.C c ON c.%ID = arrayTable.Collection

I'm looking for the most straightforward way to trigger a custom Ensemble message when a patient logs into the Personal Community patient portal. The use case is that when the patient logs in, we want to query an external email database for any new messages the patient has and import them. Does anybody know if there's any built-in functionality I can use, or if not, what the best trigger point would be?

Terminal scripts can be used to run pre-designed commands on the terminal, like a batch file.  You can write anything that can be executed on terminal, like for loop, if else and so on,  inside Terminal scripts. In this article, I will show you how to call Terminal scripts, how to use parameters in Terminal scripts and how to avoid session disconnected when running Terminal scripts. If you have any information about how to use Terminal scripts or you have any feedback, please feel free to leave a comment
