Thank you!

I wouldn't have immediately thought that would solve it but it makes sense along with your explanation.

Out of curiosity, how would you override that write statement in %CSP.Lookup?  Isn't that generated code which one wouldn't want to touch?

I thought I tried that but evidently I didn't.  Worked just right thanks!

I gave up on this and we manually create rest services and documentation. It's tedious but I don't think this was going to do what I wanted to do and we aren't keen on using Open-Exchange stuff that's not directly supported by IS.

Yeah, I spent a lot of time with the documentation. I would be interested to know if it's possible to set it all up without configuration in the management portal.  E.g. before I called the endpoint to get the keys and rotate them from the auth server, but the config does that for free.  I think there's a lot I could have missed not knowing the OAuth spec but I'd be curious to know if anyone did it without using the config.

Thanks @Luis Angel Pérez Ramos!

Yes, agreed on DTLs for HL7 - it's built for that!  In my case, yes, it's a custom object.  Also, I think for my use I will keep the request from the service to the process (the mapped record to the processing) as async.  

So I'm still a little unclear and, yes I have read and reread that page of documentation but I'm left with questions.  Let me stub out some code to see if I can narrow down my thoughts (sorry I'm really clumsey with this editor)

Class BusinessProcess extends Ens.BusinessProcess {

Method OnRequest(request as Record.From.Mapper, response as MyCustomObject) as %Status {

  // does it make sense that my response is here the custom object 
  // I'm transforming my record to?  i don't see a need to create a 
  // whole new response class just to say the record was completed . . . 
  // either the response is "" or an instance of MyCustomObject

  s response=##class(MyCustomObject).%New()
  s response.rawData1=$e(request.PropertyToExtractFrom)
  s response.RawData2=$zstrip($p(request.DelimitedProperty,""|",2),"<>W")
  d response.%Save()

  // this is where i'm sacrificing the dtl and bpl for just simple code - 
  // sounds like you say you do this for custom objects, so i think i'm good

  q $$$OK

  // does the response even matter here?  i'm not sending it to a business 
  // operation, however we do have a kind of dummy business operation we can 
  // use to send the response to and nothing happens, just kind of an ending 
  // point to say "we're done and there was no issues".

  // so i could implement something like:
  // ..SendRequestAsync("DummyOperationToSayWe'reDone",0) q 1

}

Method OnResponse(request As %Library.Persistent, ByRef response As %Library.Persistent, callrequest As %Library.Persistent, callresponse As %Library.Persistent, pCompletionKey As %String) As %Status

{

  // the documentation says i must implement this but i was able to compile without . . . 
  // you also seem to indicate it's optional.  since i'm not handling any responses 
  // from any of the business hosts this isn't necessary to implement i think.  
  // if i were to implement request would be an instance of Record.From.Mapper and 
  // response would be the response defined in the business process or operation, yes?

  q $$$OK

}

Reading my own question, I think I'm confusing JWTToObject as proper validation, but I think all that step is saying "with the JWT and key you've provided, this is a good/valid token so please proceed with what you need to do to validate claims."

Still, I look forward to your responses. 

Thanks, @Timothy Leavitt!

This was incredibly helpful.  I modified it a bit as that $CASE statement would have grown over time into something not fun to manage.

I created the main dispatch class and prepended the version to the pUrl parameter in the OnPredispatch method and then passed that into a main router class using DispatchRequest similar do what you did there.  We can maintain the routemap in that main router class to keep things more organized and standard and from there it simply acts as normal.

THANK YOU!

Setting the Java Home setting on the External Language server still gives me the same error in KaftaClient.jclient.gateway.

@Eduard Lebedyuk thanks for your response here!

I changed directions and used embedded Python and a library called kafka-python which appears to be well-used and supported.  Using this, I've had no issues getting connected to my server, plus now I have access to more commands for Kafka.  

Before I edit or setup a new External Language Server 1) do you think the %Net.Remote.Exception is related to the Java Home on the external language server not being setup and 2) if I had multiple external language servers setup, how would I tell %External.Messaging (and specifically the Kafka client) to use one or the other?

It would be ideal to stick with COS libraries and features, but I think the Python library is the best solution as it offers more in terms of an API, but I'd still like to get %External.Messaging working for other purposes.
