Thanks Robert Camper. I am grateful for your help, and I value the most your explanation rephrasing the issue with both examples, what I expect, what I get. Thanks for your didactic answer.

Thanks Alexander Koblov,

Why is $Listnext recommended?

Is it true?

The "$List" function returns a complete list, while "$ListGet" returns a specific item from a list given its index. When you need to iterate over a list, you can use the "$Listnext" function. This function allows you to get the elements of a list one by one, without having to load the whole list into memory at once.

Using "$Listnext" instead of "$List" or "$ListGet" can improve performance, as it avoids the need to load and process the entire list at once. Instead, each item can be fetched individually as needed, which is particularly useful in cases where the list is large.

🧐 Additionally we have read 💭💭 carefully:

https://community.intersystems.com/post/making-jwtoauth20

However, we do still have the same question:

What way is there to "call", "invoke", "communicate" from the other environments ( for example INTEGRATION ) with the PREPRODUCTION Resource Server in order to Validate the Token?

That is to say, the question in another way would be:

What mechanism exists to communicate from an Environment A (Integration) with an Environment B (Preproduction) with the mission to Validate the Token from Environment A using the centralized Resource Server available in Environment B?

👀 Thank you very much for your attention, and thank you for your answers.

Best regards

As a reference a the Java solution:

Could be:

import java.util.*;

public class DnaStrand {

  static final Map<String,String> letters = Map.ofEntries(Map.entry("A","T"),Map.entry("T","A"),Map.entry("G","C"),Map.entry("C","G"));

  public static String makeComplement /*🧬🔁🧬*/ (String dna) {
    StringBuilder result = new StringBuilder();
    
    for(String letter:dna.split("")){
      result.append(letters.get(letter));
    }
    return result.toString();
  }
}

Would you like to improve this in ObjectScript?

Are you able?

I hope you feel challenged with this exercise

Hello Dewey Hunt, thanks for your replies:

1) I am looking to develop current skills and/or generate new ones. But it would be prefered to deep into ObjectScript or into some skills related to interoperability.

2) It is interesting what you write about state of flow

Greetings

As a reference you could observe my following solution in Java:

import java.util.Arrays;

public class Kata {
    public static int findShort(String s) {
        String[] words = s.split(" ");
        int shortestLength = 0;
        for(String word : words){
          if(shortestLength == 0){
            shortestLength = word.length();
          }else{
            if(shortestLength > word.length()){
              shortestLength = word.length();
            }
          }  
        }
        return shortestLength;
    }
}

A unique answer and quite useful, Robert Camper

Could you explain us how could we download, install and start to use a free version od the Dicom Dvtk Ris-Emulator, please?

We have been developing the Web Service following the official documentation:

The target system, asks us to implement a WebService with MTOM to send the zip with a csv inside, as follows:

When importing the WSDL of the target system, the header of the "cargarFichero" (loadFile) method was generated with "fichero" (file) as a "%xsd.base64Binary".

We changed file to "%GlobalCharacterStream".

This way the file, the csv, is sent unencoded, inside a CDATA

Being the response of the target system:

However, as we can see in the first image, the target system would need, would require, that we send the file encoded in binary, since it says:

Content-Transfer-Encoding: binary

When we adapt the file to be "%GlobalBinaryStream" we see the following trace, where it is encoded in binary:

When sending binary encoded, the target system also responds:

In short, the target system needs from us:

"add the "name" parameter inside the "Content-Type" header when attaching the file. Your client should generate this parameter to avoid getting this error."

Being the full comparison between what is sent by ensemble (without the "name" parameter, therefore incorrect) on the left; and what is generated by the SoapUI (with the name parameter, correct), on the right:

➡️ Please could you point us to examples, documentation, projects, code, that we can use as a reference to investigate, research and complete the development? 💭

We have also investigated the following answers:

Thank you very much for your time, reading and responding.

Thanks for your help.

Thanks Jeffrey Drumm for your help, because the answer you have proposed works as expected

In addition you have helped us to learn about the square bracket syntax [] to find a value in a field in all repeating segments

Plus you have shared with us how does it outputs the values of the repeating segments: inside a string where each field's value is inside "<...>"

Thanks

Thanks Jeffrey Drumm for your reply

We have observed that our Ensemble's version is:

It does not contain "RegexMatch" function in Ens.Util.FunctionSet

We have tried to develop a rule using Length and Contains functions

We would need to detect the following:

if at least one OBX3.1 is "24642" or at least one OBX3.5 = "24642"

What we have developed does not work, and we do not know why

Could you help us, please?

We have been testing, developing and debugging some hours, and we would really appreciate your time, replies, effort, and examples, please

The rule which does not work is:

We have written:

}

When we execute it, Ensemble throws an exception in the message viewer:

➡️ ERROR #5001: <INVALID OREF>zcargarFichero+16^WSCLIENTE.HistoriaClinica.FicheroVacuServiceSOAP.1

We think it means that the variable "HttpRequest" is an invalid oref

How could we continue?

What steps would you recommend us to add the parameter "name" inside "Content-Type" header when we send a MTOM attachment using a SOAP request?

Thanks for your time, answers and help 💭
