Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.

Preface: our small, but very ambitious company called “Black Mushroom Studio” came up with an idea for an e-commerce project and a mobile app that would let users pay for certain goods/services via a payment aggregator.

What we had initially: an Android app skeleton that, of course, liked communicating via HTTP and JSON, and a payment system with an API – web services with SOAP content.

Goal: make it all work together.

Hi-

Can someone please explain the affect of the Failure Timeout on an ensemble business operation with a EnsLib.HL7.Adapter.TCPOutboundAdapter

Is this setting indicating the number of seconds that the operation will attempt to resend a message to a target before it fails?

How does this setting affect message processing of messages that fail because of a missing or failure response code that comes back in an HL7 message response?

REST in Pieces

A beginners guide to develop Ensemble RESTful web services.

Background

Before you start reading this short introduction please go through the on-line documentation of Ensemble with special attention to chapter “Creating REST services and clients with Ensemble”.

The approach in the documentation is undisputable the fastest and easiest way to create RESTful services. As a beginner I went through the documentation and I had several questions. This short article is listing those questions plus my humble answers.

Hi all,

We're in the process of creating several courses for creating custom business components for productions. This includes custom business operations, BPL processes, and custom business services. Custom Business Operations and Custom Business Services are both aimed at software developers while BPL processes can be also be created by business analysts. What are some gotchas or best practices you've learned that you wish you knew when first building these components?

We'd love to include what you've learned into these courses so others can learn from them as well!

Diagnosing Framing Errors

Framing refers to the characters that mark the start and end of an HL7 message (or other types of framed messages). Most HL7 services and operations have a Framing setting that allows the user to define this framing. The most common choices are available as defaults, but with the AsciiMM/NN setting, components can be configured to recognize any framing characters.

Right now I have a developer/free version of Cache 2016.1 on my local dev box but it doesn't have Ensemble installed, is there a way to get Ensemble?

After having gone to the 2016 Global Summit I want to play around with it on my own and see what it's capable of.

Thanks

Hi All

I have a BP which has a transformation.

when I run the process I end up with the following error:

----

ERROR <Ens>ErrBPTerminated: Terminating BP Propirion.BP.GetServices # due to error: ERROR <Ens>ErrGeneral: Object is immutable
+
ERROR <Ens>ErrGeneral: Object is immutable

----

I have created a context named : HL7Message type of: EnsLib.HL7.Message and in the start of the BP assigned the request to it (using set in assigned activity)

What did I miss ?

Thanks

Gadi

Some time ago, I was started to work at a new company even in other country, and more important in a different sphere when I have not been worked before, in HealthCare. It's a very new project even for company. Since I have not experience in HealthCare, I looked at what I can use in my project, and found that I should not reinvent the bicycle, and think about how to store all my data which I need and how to get access to this data. And I can use FHIR, which is looks like everything what I need, what else I need it's just a client.

This short article was motivated by a problem of one of my customers. They use Ensemble to integrate many systems, some of them use just plain files.

So they naturally selected File Outbound Adapter to write into target file. Things were running smoothly for years, until recently, when the volume of data being written to the file reached large size of tens of megabytes. The operation took around half an hour to complete, causing timing problems where subsequent operations within the process had to wait, and third party system was not happy to wait so long.

Hi

I do not really have much information yet about an upcoming mission but i know it is about to seal a flatfile and then send it further. I think SHA256 HMAC will be used. There is a fixed sealkey to be used each time. Does anyone know if the Ensemble supports this ? I have looked in the documentation but not really found anything .

Regards,

Michael Lundberg

Hello everyone,

Does anyone know how to create integration tests using the Cache unit test framework in order to test an Ensemble production?

For example, what would be the best way to create automated tests for a BPL that calls multiple business operations (SQL, WebService ...)?

Should we create some kind of mock service/operation to simulate the response from the business operations ?

New keys for Field Tests?

The FT keys InterSystems currently make available to us in the zips from the download pages are due to expire at the end of this month (31-Aug-16). Will there be new keys soon?

Also wondering when we might expect new FT builds for 2016.2 and 2016.3. The last published ones were 24-Jun-16 and 16-Jun-16 respectively.

I haven't seen an Atelier update for a while either.

Is there an out-of-the-box or accepted standard method for loading up mappings between different code sets and then referencing these mappings (both directions) from DTL? First thought was the built in Lookup() and corresponding data tables but these only work in one direction (key -> value) and not the reverse. Obviously I can build my own classes to support a two way mapping but am wondering if there's a standard way of achieving this. The mapping should contain the code and display name from each of the code sets and allow mapping based on either code or display name.

Thanks
