In this article, I will show how you can easily containerize  .Net/Java Gateways.

For our example, we will develop an Integration with Apache Kafka.

And to interoperate with Java/.Net code we will use PEX .

Architecture

Our solution will run completely in docker and look like this:

Java Gateway

First of all, let's develop Java Operation to send messages into Kafka. The code can be written in your IDE of choice and it can look like this.

In short:

• To develop new PEX Business Operation we need to implement  abstract com.intersystems.enslib.pex.BusinessOperation class
• Public properties are

InterSystems states that Caché supports at least three data models – relational, object and hierarchical (globals). On can work with data presented in relational model in a program written on C# the same way one works with any other relational DB. To work with data presented by object model in C# one needs to use .NET Managed Provider or some kind or ORM. And starting with version 2012.2 one can work directly with globals (or use direct access to hierarchical data) via Caché eXTreme for .NET. 

Hi everyone, do you have any idea how to find this error or the meaning of this error <STORE> 15 ^%SYS.BINDSRV i always get this once a week.

Hi Community,

⏯ Extending Interoperability with PEX & Containers

i have looked for $zf function，it says $zf(-6) will work,but it doesn't work out actually,anybody can give me a dll file which will work with $zf,if you should show me the way making the dll that is best!thanks!

Good Morning,

I have this question for a long time. When I make an insert by SQL from an external application in the fields of type %String, if they are empty, it writes the character $c(0) in the global.

Is there a way so that if an Insert is received in a field of type% String with null value instead of the $ c (0) it leaves it empty?:

I have the class defined like this:

Class User.MiClase Extends (% Persistent,% XML.Adaptor)

and the property like this:

Property myProperty As% String;

I have tried creating a trigger or setting default values but it doesn't work.

Trigger DespuesInsert [ Event =

I am trying to use IRIS Native API in .NET code I see following code snippet here https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

  IRISReference valueRef = new IRISReference(""); // set inital value to null string
  iris.ClassMethodString("%SomeClass","SomeMethod",valueRef);
  String myString = valueRef.value;               // get the method result

But IRISReference is not available as a type.

 What reference (dlls) do I need to add for that? I have InterSystems.Data.IRISClient.dll , what else do I need? what am I missing here?

Migrate from Java Business Host to PEX

With the release PEX in InterSystems IRIS 2020.1 and InterSystems IRIS for Health 2020.1, customers have a better way to build Java into productions than the Java Business Host. PEX provides a complete set of APIs for building interoperability components and is available in both Java and .NET. The Java Business Host has been deprecated and will be retired in a future release.

Advantages of PEX

• Allows developers to create any Production component in either Java or .NET
• More complex message structures can be passed between components
• Simplified settings
• Simp

Dear,

I have a visual studio c# library (.net framework 4.7.2) where I want to use EF.  I cannot see my ODBC connection in datasource when I select a ADO.NET Entity Data Model for EF designer for database.

I followed the installation for CacheEF.zip file. (C:\Cache\Cache2010v2\dev\dotnet\bin\v4.0.30319)

Any Ideas,

Kurt

Edit:

May have found the issue but not the solution.

"SELECT * FROM wmhISTORYdETAIL" runs as a passthrough without asking for the DNS.

but

'SELECT Count([wmhISTORYdETAIL].[HistHMNumber] AS CountOfHistHMNumber FROM [wmhISTORYdETAIL] WHERE ((([wmhISTORYdETAIL].[HistMovType])='Receipt') AND (([wmhISTORYdETAIL].[HistMovDate])>=Date()-1) AND (([wmhISTORYdETAIL].[HistMovDate])<Date()));'

asks for the DNS but both are linked to a table that has the password saved.

Any Ideas please?

Rob

Hi

I have created an MS Access database with a passthrough query to our Intersystems Cache WMS system.

Does anyone have a Dockerfile for .Net/Java Gateways to share?

I'm trying out PEX and I think being able to run it as a docker container would be great.

To clarify I'm interested in container without IRIS, gateway only.

Hey Developers,

We're pleased to invite you to the upcoming "Development of Interoperability Business Hosts with PEX in Java/.Net" webinar by InterSystems Russia on July 16 at 10:00 (UTC+3, Moscow time)!

Hey Developers,

We're pleased to invite you to join the next InterSystems IRIS 2020.1 Tech Talk: Using Java and .NETon June 16 at 10:00 AM EDT! 

In this installment of InterSystems IRIS 2020.1 Tech Talks, we put the spotlight on extending InterSystems IRIS with your own custom Java and .NET code. We will demo how to create a custom interoperability component with the new Productions Extensions (PEX) feature. Following that, we’ll demo how to call Java or .NET code from any ObjectScript code.

Hello,

I am having a problem with SQL Select, the command in portal is OK, show all items, but when I use a CacheDataAdapter in VB .NET show the message 'Incorrect list format 0>=0'.  What could be this message? Because is the same SQL command.

Best Regards.

I am using healthshare 2017.2 & developed API in vb.net . sometimes API gets error when system tries to connect Cache Database. why this error occurs randomly ?

Hi Community!

Hi !

I am getting below error in my .NET MVC project, I am IRIS Entity Framwork, in the database table filed and model having the same datatype int.

The specified cast from a materialized 'System.Int64' type to the 'System.Int32' type is not valid db Table creation Id field is created with [xDBC Type = BIGINT]

Please kindly advice me.

Thank you

Hi Community!

We are pleased to invite you to the upcoming webinar in Spanish: "How to implement integrations with .NET or Java on InterSystems IRIS" / "Cómo implementar integraciones con .NET o Java sobre InterSystems IRIS" on May 20 at 4:00 PM CEST!

⏯ Developing Progressive Web Apps

Hi There,

I have Microsoft Visual Studio Community 2019 installed and tried to setup the entity framework as per Using Entity Framework with InterSystems IRIS Data Platform (https://learning.intersystems.com/course/view.php?id=1046)  tutorial but I can't see the ISC data source in MS Visual Studio's Data source section. Does this mean that MS VS Community 2019 is not supported with the Entity Frmawork?

I’m excited to announce that InterSystems will be joining the open source community for InterSystems ObjectScript extension to Visual Studio Code. Early this year I posted that we were on a journey to redefine the future of our IDE strategy, and what came out of that is Visual Studio Code is the IDE that can support that future.

While I can query the HL7 message class EnsLib.HL7.Message (EnsLib_HL7.Message for SQL) to my heart's content in the SQL Shell or the Management Portal's SQL page, I can't seem to SELECT anything other than ID/%Id from an ADO/ODBC client. Properties such as TimeCreated, Name, MessageTypeCategory, etc. all seem to prevent the query from ever completing EXCEPT when I provide the ID as part of the WHERE criteria.

This works fine in the Management Portal and Shell:

SELECT head.ID As HeadId, body.ID As BodyId, body.Name as BodyName
FROM Ens.MessageHeader head
INNER JOIN EnsLib_HL7.Message body
ON

trying import ClassDefinition File via <IRISClient.Ado.IRIS> result with error:

am i missing something?

        public void LoadClass()
        {
            
            // import/ update <Installer.Package> to %SYS NameSpace
            using (var c = new IRISConnection("SERVER=127.0.0.1;PORT=51773;NAMESPACE=%SYS;USER ID=_system;PASSWORD=SYS;"))
            {
             

will InterSystems fix the Transaction-Handling for  the  .Net Connection Provider?

Nor the  Property IsTransactionAcvtive nor TransactionLevel is set on the  Connection  when using BeginTransaction.

Latest PreView will give me   problem as InterSystems removed removed the TStart() Option to create the Transaction that way which gave back a TransactionObject whith working versions...

I am developing a viewer for Crystal Reports using the Crystal Reports for Visual Studio (CR13SP26).  I have also installed the latest ODBC Drivers for Cache, but when I connect some reports to the Cache database using a connection string, I get an error that I failed to retrieve data from the database, and it reports the Database Vendor Code 30.  Has anyone used Crystal Reports connecting via a connection string and received this error?  If so, how did you correct it?

Thank you,

Brian Cromwell
