Intro

In a fast-paced digital era, effective communication is crucial. This article introduces a Java-based chat project, combining the strength of IRIS database and ChatGPT intelligence. Built on Java, it goes beyond real-time messaging, leveraging IRIS and ChatGPT for an enhanced chat experience. Also, the name of the project references the cultural classic - Star Wars.

GmOwl is a solution that offers an organized and engaging learning platform. It was developed to cater to the increasing need, for learning tools providing a versatile quiz environment that meets users requirements.

The main objective of GmOwl is to deliver an user experience for individuals participating in quizzes while giving administrators comprehensive control, over content and user engagement.

GmOwl uses Java EE with MVC template, and the InterSystems IRIS database is used to store data. The InterSystems JDBC Driver is used to connect to the database.

Motivation

The motivation behind the InterLang project is rooted in the innovative integration of LangChain chatbot agents with the Fast Healthcare Interoperability Resources (FHIR) framework to revolutionize conversational social prescriptions in healthcare. This project aims to leverage the rich and standardized data available through FHIR, an emerging standard in healthcare data exchange, to inform and empower these advanced chatbot agents.

Hi Community,

Watch this video to see how to connect to InterSystems Cloud Services from your Java application using the InterSystems JDBC driver:

Hello,

I work on deploying IRIS using Kubernetes operator and Red Hat OpenShift. I encouraged another team working on Java application to consider using IRIS as database. My team deployed IRIS cluster using two mirrored data pods for the other team. The other team asked me for the connection information.

To learn how to use Java with IRIS, I attempted to deploy two apps from Open Exchange:

In my previous articles, I described my Command Line Extension to NativeAPI.
Of course, this is also available for any other NativeAPI package.
So I created this example as a demo for the actual Java Contest.
<--break->
The package contains also an IRIS server in Docker for the demo
It is evident that it also works with any remote IRIS server.
You just have to provide it with my NativeAPI CommandLine Extension.

Consider a Natural Key with an Identity (Serial) field.

I cannot seem to acquire the generated value after persisting my entity. That is, the returned entity by Spring Data's "save" does not have the generated value.

The value is generated by the database, and I can query it after repository.save(entity).

I have done some testing and created a Github repo with it...

[Video] What is PEX

Hi Developers,

See how the Production Extension framework (PEX) allows you to build custom interoperability components in .NET or Java without first learning ObjectScript.

With PEX, you can code in a familiar language and take advantage of established code libraries to add components to a production.

I have two local instances:

  • IRIS for Windows (x86-64) 2018.1.2 (Build 626_3U) Wed Jun 12 2019 19:07:59 EDT
  • IRIS for Windows (x86-64) 2019.1 (Build 510U) Thu Mar 14 2019 14:13:37 EDT

I'm using Java Gateway to talk to external system.

Both instances are using the same:

  • jar
  • generated class
  • java version


They are calling the same method with this java signature:

Recently I started moving some of our JDBC Gateway configurations over to using the Microsoft JDBC Gateway driver instead of using the jTDS open source driver. I have noticed since then that those Objects that are using Microsoft JDBC Driver are throwing a lot more errors than the jTDS driver ever did, which I can understand however I am puzzled that I keep running into an issue with the Java Gateway Service within the Interoperability engine.

Introduction

This article aims to explore how the FHIR-PEX system operates and was developed, leveraging the capabilities of InterSystems IRIS.

Streamlining the identification and processing of medical examinations in clinical diagnostic centers, our system aims to enhance the efficiency and accuracy of healthcare workflows. By integrating FHIR standards with InterSystems IRIS database Java-PEX, the system help healthcare professionals with validation and routing capabilities, ultimately contributing to improved decision-making and patient care.

What about DMN?

A few months ago, I faced a significant challenge: streamlining the handling of business logic in our application. My goal was to extract the business logic from the code and hand it over to analysts. Dealing with a multitude of rules could easily result in a code littered with countless "if" statements, especially if the coder lacked an understanding of cyclomatic complexity. Such code becomes a source of pain for those working with it—difficult to write, test, and develop.

Hello all,

I am trying to start java gateway and constantly getting an error in terminal:
"%RemoteService+3^%Net.Remote.Gateway.1 *%Exception.StatusException ERROR #5023: Remote Gateway Error: TCP error on port '55555', ensure there is an Object Gateway running on this port". I've checked jvm and it is running properly, telnet also is able to connect to the port.

Has anyone encountered this issue before?

Once again I would like to know, if there are any plans to make Java libraries available through normal channels like public mvnrepository, like the whole world it's doing, where anyone can find any JDBC driver to any database in the world but InterSystems.

Currently there is only some useless garbage. There are just very empty files. What was the point of posting it there?

NativeAPI for Java from WebTerminal

Based on the successful solution for my 2nd contribution to the Contest
I used an adapted version for this package. And have some findings I'd like to share.

Multiple communication steps over CPIPE may take time.
You won't recognize it on a fast machine. But a slower box with
Windows + Docker Desktop + your browser (and more) is neither
"Speedy Gonzales" nor a "Road Runner". 🙂
