Another option is to look into the Request Transformer Advanced, since this plugin support regular expressions and allows for dynamic content: https://docs.konghq.com/hub/kong-inc/request-transformer-advanced/

Hi Akshay,

this functionality was teased at Virtual Summit but is not released yet. Also, this will be an IRIS for Health feature, as the DTL Generator works on inbound and outbound pairs of HL7 messages.

Best,

Hi Duncan,

great to hear that you find the community edition beneficial! We are currently working on making the IRIS for Health Community Edition available on the docker store as well. I can't give you an exact time window, but it shouldn't be too far away. Stay tuned, it will be announced on the developer community when it is available.

As Sylvain has pointed out, you can always pull the images from the WRC Distribution page if you are a registered partner. The offerings on AWS, Azure or GCP can still be helpful with zero cost, as you often get a voucher when you sign-up for a new account. Enough for playing around for sure.

Best,

Stefan

You have various options, depending on what you want to achieve:

1. Added a property of type %DynamicObject or %DynamicArray to a persistent class
2. Store the JSON content in the Document Data Model
3. Parse a JSON structure as Eduard indicated and generate the corresponding persistent class(es).
4. I would not advise to use %Document.Object. Use the Document Model instead.

With option 1) and 2) you don't need to define a schema at all, but can easily persist and manage your JSON content as objects. No SQL access to individual properties of the JSON content for option 1). With the document data model you can add support for SQL queries for individual JSON paths.

Option 3) is work, but doable. Figuring out the correct datatypes will be the greatest challenge. If you have JSON schema instead, your life is much simpler. 

Hi Tosh,

it seems your path is not correctly setup as the process is not able to identify the underlying C binding libraries. I assume you are using the 64-bit version of Python. Also I want to point out that we currently only support Python 3 up to version 3.3 as later versions introduced quite significant changes in string handling. We are working on supporting versions beyond 3.3 at the moment.

HTH,

While it is true that Generics are not supported by the Java Gateway I would like to provide a little more guidance on why that is the case and how to deal with this not uncommon situation.

The Java Gateway (and the dotNet Gateway by the way) allow you to interface between ObjectScript and another language environment and obviously there are concepts in one language foreign to the other. Our approach to the Gateways is to support basic structures and concepts which are similar in both languages or easily translated between them. A "complete" approach would not only take very long to implement, would be hard to verify for correctness and because of the rules you had to apply not easy to understand. It would defeat the basic rule "power through simplicity".

Generics is a case which is not easily mapped and therefore not supported. Of course you can come up with ideas how to support such a concept with what the server-side environment has to offer, but keep in mind what I wrote above.

 Every time you encounter such a situation you find yourself in a situation where the Java API you would like to call from our side of the fence is too complex and properly includes functionality you don't want to interact with in its entirety.

The Facade pattern allows you to easily work around this challenge. Build a basic API around the functionality you want to interact with on the Java side and import your handwritten entry point. This makes the interface much more manageable for the gateway and all the participating parties as the contract between Java and ObjectScript is very clear with this pattern.

Hope that helps,

Stefan 

I am not sure if I got the question right. If you already have a Zen or Zen Mojo application and would like to add a login page, I strongly recommend to develop the login page as a separate CSP/ZEN or Zen Mojo page. From my experience Zen Mojo is too heavy just to build a single simple login page (as it is designed for a complete SPA - single page application), so CSP or ZEN is recommended. If you are starting from scratch I usually recommend to pick a modern framework like Angular you feel comfortable with and communicate via JSON/REST to the backend. Responsiveness is usually achieved by a mix of picking UI libraries that are responsive by default (e.g. Bootstrap) and your own responsive CSS implementation. If you require a native application for mobile devices on iOS and Android (e.g. to interact with the camera) you have to be a bit more specific. But your options are either a native application (Swift or Java) or a hybrid (e.g. via Cordova or Ionic). The communication channel always is JSON/REST, so you have to start by designing your REST interface first, no matter what your web client looks like. At least for the majority of the use cases. Please let me know if you require additional information. HTH, Stefan

I also advice to use a local mailserver, which eases configuration and testing. A popular example is PaperCut:

It is much easier to spot configuration issues as you can take a look at the mailserver logs as well.

Interesting thought Sebastian.

We haven't run dedicated benchmarks on this topic, but I can provide some guidelines.  You have to acknowledge that creating a dynamic object or a dynamic array is the most expensive part of your code style compared to just using plain variables. You are instantiating an object.

If you run a simple benchmark like the following you can observe a difference:

ClassMethod TestAll()
{
    set iterations = 1000000
    
    set start = $P($H,",",2)
    for i=1:1:iterations {
        do ..TestDynamicObject()
    }
    set time = $P($H,",",2) - start
    w "Dynamic Object test case took "_time_" seconds",!
    
    set start = $P($H,",",2)
    for i=1:1:iterations {
        do ..TestVariables()
    }
    set time = $P($H,",",2) - start
    w "Variable test case took "_time_" seconds",!
}

ClassMethod TestDynamicObject()
{
    set do = {}
    set do.setting1 = "value"
    set do.setting2 = "value"
    set do.setting3 = "value"
    set do.setting4 = "value"
    set do.setting5 = "value"
    set do.setting6 = "value"
    set do.setting7 = "value"
    set do.setting8 = "value"
    set do.setting9 = "value"
    set do.setting10 = "value"
}

ClassMethod TestVariables()
{
    set setting1 = "value"
    set setting2 = "value"
    set setting3 = "value"
    set setting4 = "value"
    set setting5 = "value"
    set setting6 = "value"
    set setting7 = "value"
    set setting8 = "value"
    set setting9 = "value"
    set setting10 = "value"
}

The result on my local machine looks like this:

USER>do ##class(User.DOAPerf).TestAll()
Dynamic Object test case took 13 seconds
Variable test case took 0 seconds

So there is a significant difference IF your code is called often enough to actually make the overhead noticeable. In the above example I called each method 1 million times. If your code is not called that often you will not observe a difference.

As a general advice I would not nest the dynamic objects or dynamic arrays when used as you describe it, as this increases the number of object creations.

Long story short: Stick with variables in performance-critical parts of your application. In other parts of your application you can use dynamic objects or dynamic arrays as temporary objects for sure, just make sure you only nest them when absolutely required. Passing complex structures between method calls with dynamic objects can be very elegant.

Embedding a JLNP file in a CSP page is the same as in a plain HTML page. You have to embed and load the JLNP file using something like the following snippet:

<script src="https://www.java.com/js/deployJava.js"></script>
<script>
    var attributes = {} ;
    <!-- Base64 encoded string truncated below for readability -->
    var parameters = {jnlp_href: 'your_applet.jnlp',
        jnlp_embedded: 'PCEtLSANCi8qDQogKiBDb ... bmxwPg=='
    } ;
    deployJava.runApplet(attributes, parameters, '1.8');
</script>

In order to figure out the value for the jnlp_embedded parameter you have to base64 encode the contents of your JNLP file. The JNLP file has to be accessible from the relative link provided by the parameter jnlp_href.

This tutorial explains how to embed JNLP files:
