Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.
New to coding in InterSystems IRIS® data platform? Try this brand-new learning program to get the basics, and see how to develop an application with InterSystems ObjectScript alongside your language of choice: Java, .NET, Python, or Node.js.
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.
PEX is a new InterSystems IRIS feature to allows extends IRIS with existent features from Java or .NET.
It is possible create interoperability inbound and outbound adapters, business services (integrate from external to internal) and operations (integrate internal to external).
To create a PEX component it is necessary import .NET (InterSystems.EnsLib.PEX.*) or Java (com.intersystems.enslib.pex.*) packages and extends or implements the properly class.

I am working on a project that will interact with some software called ROS (Robot Operating System). One of the development challenges we have is as follows:
ROS uses web sockets... So one connect with ws://localhost:9090 to the web socket server. It starts off as http, but then "upgrades" to web socket. It then keeps open this "tunnel" for bi-directional communication..
I need something like a HTTP Outbound adapter, but the Web Socket version of it...
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.
Any news about JDBC driver and Hibernate dialect on a public java repository, like mvnrepository? Today I need to download the jdbc driver and hibernate jar, add as an external resource on my maven config file to works.
Hi Developers!
Let me share with you some exercises from a workshop about developing interoperability components in Java using PEX (Production EXtension).
You will find slides and step by step exercises about:
Understanding simple PEX components coded in Java.
Making some changes on them.
All built using containers, so you don't need to build a local Java environment.
InterSystems Atelier has been tested with OpenJDK 8. The InterSystems Eclipse plug-in is currently available for Eclipse Photon (4.8), which requires and works with Java 8.
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.
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.
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 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.
Spring Boot is the most used Java framework to create REST API and microservices. It can be used to deploy web or executable web or desktop self-contained apps, where the application and another dependencies are packaged toghether. Springboot allows you do to a lot of functions, see:
My newest app includes a java routine to read data from Excel 95, 97, 2000, XP, and 2003 workbooks and write the data into IRIS globals using Java Native API library.
If you have Git and Docker installed, clone/git pull the repo into any local directory
Trying to evaluate it and work out how we could use it.
As a standard application database. Object or relational etc. does not matter.
Issue is ObjectScript.
So:
1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?
In this article, we will establish an encrypted JDBC connection between Tableau Desktop and InterSystems IRIS database using a JDBC driver.
While documentation on configuring TLS with Java clients covers all possible topics on establishing an encrypted JDBC connection, configuring it with Tableau might be a little bit tricky, so I decided to write it down.
Working on implementation FHIR to my project, I found interesting project HAPI-FHIR, which could help me to quickly launch my FHIR api server with InterSystems Caché as a storage, because this projects uses Hibernate to connect to database, as an example they use DerbyDB. I tried to change settings to use InterSystems Caché, but unfortunately it does not work and throw some errors inside HIbernate. As I found in Caché documentation, I have not some many options, I just have to set Cache dialect, and set database url.

With the release of InterSystems IRIS, we're also making available a nifty bit of software that allows you to get the best out of your InterSystems IRIS cluster when working with Apache Spark for data processing, machine learning and other data-heavy fun. Let's take a closer look at how we're making your life as a Data Scientist easier, as you're probably already facing tough big data challenges already, just from the influx of job offers in your inbox!
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.
