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?

I'm really interested in contributing, but this issue is a huge stopper, and I don't want to do anything.

@Bob Kuszewski @Jeff Fried and whoever can answer on this 

I have questions about Java Versions needed for setting up a %JDBC External Language Server

I'm trying to start the %JDBC. External Language Server my local instance of IRIS (2023.1.2). I've recently upgraded Java to version 21.0.1 

When starting the External Language Server, I get this error message:

Has anyone noticed that when IRIS is forced down that the EnsLib.JavaGateway.Services do not properly shut down and release the ports? While we can write a shell script to kill the processes at the OS level, I was wondering if anyone experienced this issue.

We are working on our Mirroring setup/failover and had the team testing forcing the Primary down to make the Backup to become the Primary Server. When this happened and we failed back, IRIS could not restart the JavaGateway.Services because the ports were still in use.

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.

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.

how it works

The new $system.external interface (aka "InterSystems External Servers") is used to call/integrate with external language code/libraries, it replace the old gateways (for example Java gateway) that required the import of proxy objects.

Note that the documentation for the old gateways has been removed from IRIS, so only the new $system.external interface is somewhat (i.e. insufficiently) documented.

Regarding the migration from old gateway to new  $system.external interface the documentation says:

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?

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.

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.

Maven Projects mixing ObjectScript and Java

What is Maven?

Maven is a tool, hosted by the Apache Software Foundation, for building and managing any Java-based project. Apache Maven is the best source of information.

Why Maven?

Overview

In our previous post, we discussed the motivation for developing a chatbot agent with access to FHIR resources. In this post, we will dive into the high-level design aspects of integrating a Streamlit-based chat interface with a Java SpringBoot backend, and enabling a LangChain agent with access to FHIR (Fast Healthcare Interoperability Resources) via APIs.

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.

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". 🙂

First observation you launch your OS command and see NO result
On the console, you just sit there and expect a reply.
Establishing the Connection to IRIS is a typical case.
Jour redirected Output is just empty.  

There are situations when your only access to a server is using a web browser,
and there is just no chance of a Terminal or Console access.
The Online Demo Server is such a case.

So you have WebTerminal. That's fine for ObjectScript and Embedded Python.

But my demo is straight Java. And is interactive.
$ZF(-100...) is some aproach. But it's rater batch-oriented and not interactive.
@Enrico Parisi  presented a nice extension to WebTerminal recently.
It's close to my own packageWebCommand that I presented a year ago.

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.

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.

I think this demo is easy to follow and shows the essential features.

This is the related article to the package in Java Contest. 
I decided to present a CRUD++ Global Editor based on IRIS Native API for Java.
++ because it’s a little bit more than just Create, Read, Update, Delete
Visualization of a global is always important to review results immediately.

Hi,

      I am trying to use a Jreport catalog which had been saved by a different user.  But when I save the catalog I am getting an error "Access is denied".

So does that mean same catalog can't use by different users ?

Can anyone please provide a solution for the Jreport same catalog can use for different users. ? 

Thanks

Jude

Try a hands-on exercise in the language of your choice to get familiar with the multi-model architecture of InterSystems IRIS!

These recently updated exercises are available in ObjectScript, Python, Java, and .NET.

This question originally appeared in the comments of the post: Using the new InterSystems IRIS Hibernate 6 Dialect for a Springboot Project
 

Can you please any one assist me for How to connect with the InterSystems IRIS in Java(Quarkus) version 3.0. 

Is there a way problematically to see what Operations/Services are attached to a EnsLib.JavaGateway.Service and if there are issues with the EnsLib.JavaGateway.Service to stop/start those Services/Operations that might be attached to it?

Thanks

Is there a best practice to set the memory options (classic xms and xmx) on the JavaGw service in the production?

What can be recommended?

Like specifying 1024M for xmx is for a single process? that process can't grow beyond that value right? what happen if the process reach the memory limit?

Thanks

Pietro

As an example of an application on Java working with Hibernate dialect for IRIS, wanted to use RealWorld application, and found realization for Quarkus. RealWorld application is an example of an application close to some real one, with already prepared tests for the backend. Most of the examples of realizations can be found here

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.

So, I needed to start Java Gateway, and found, that it does not want to work with the latest Java versions, I tried 20, 18, 17
