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.
I'm new to Objectscript and Intersystems development. I've read documentation and some examples and succeded to import my Java class file into HealthShare using the Java Gateway Service. To import my class i tryed both methods (Wizard, or scripting) with success.
Everything works great, i see my imported class inside the namespace, and i can call the methods.
Happy new year! I’m Raj Singh, InterSystems’ product manager for Developer Experience and I’d love your feedback on how you use IDEs today and your thoughts for the future.
I trying to get the DisplayList data of the ValueLIst from Java using Springboot. when I try to get the DislayList data via java code but I'm getting the VALUELIST data. I don't get any idea to get that DisplayList data. Below is the example
I am under the impression that inside HealthShare you can Services, Processes, and Operations. The service takes incoming data, the processes can process that data, and then the operations can send that data out.
I am curious if anyone has any experience, guides, or advice on how I can send data to a service using a Java application. I intend for the data to be in XML format. I am also curious if I succeed at picking up the data in the service, how I send the data back to the Java application using an Operation.
My developers are reporting many more NullPointerException errors when using Atelier then normal lately. This happens 'randomly' when moving about Eclipse. Anyone know what can cause this? One or two during a work session was normal but it's getting in the way of work.
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.
Hi folks. I'm having trouble using the native iris API in an environment running wildfly 16. Here's a piece of my java class and stackTrack, I'm using jdk 8.

Hi! I am working in a java project (Spring Boot+ Maven + Hibernate) using jpa/hibernate to manage the persistance with the IRIS database from the Docker image (store/intersystems/iris:2019.2.0.107.0-community) and I've found an issue using the IRIS instance, when I define tables with relationships OneToMany, ManyToOne or ManyToMany and I try to fetch all the rows of the tables using the default method findAll (JpaRepository implements that method to get all the rows by default) the query automatically exceeds the limit of licenses availables.
In my production I receive an XLFO stream and I would like to pass that to the FOP pdf rendering engine to produce pdf files .So far in my research that can be achieved through ZEN .I would like to create an operation that will take advantage of that and be able to pass my XLFO stream to the operation and create pdf files I found something similar here but for some reasons I get errors like below if any one understands what they mean please advice or someone who had to do something sim
I'm trying to create a simple wrapper class around a JSON schema validator library, written in Java, and calling this functionality through the Java Gateway of IRIS 2019.1.
My Java wrapper class has a constructor like this:
public JSONValidator(char[] jsonStream, char[] schemaStream) { ... }
Recently I reread this article by @Bernd Mueller. It's about calling DELFATE function from zlib library. In this article I'll demonstrate several different approaches to callout libraries, we'll build the same functionality (compress function) in several different languages and compare them.
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?
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.
This is a FYI for anyone who has experienced the following error after upgrading an existing instance to any product based on Caché 2017.2.2. In our case, the products are HealthShare HealthConnect for Redhat x64 and for Windows x86-64 but I believe it would be a common problem for any InterSystems product on any platform, if based on Caché 2017.2.2. After upgrading our development instance from 2016.2.2 to 2017.2.2, we experienced the following errors when attempting to start a pre-existing Java Object Gateway that was defined prior to the upgrade:
Currently, I'm working with a Java Gateway, and I have the following problem. When importing a class into IRIS, which uses methods from a generic class, I can not find the general methods I need. I'm talking about the test2 method from the class test. How can I import the java method that returns a generic?
I am using java gateway imported/proxy classes and JG business service. I need to load a dll at run time.
I use System.loadLibrary/System.load when in java. I’ve tried $ZF(-3,” C:\Windows\System32\pteidlibj.dll”) and $ZF(-4,1,"C:\Windows\System32\pteidlibj.dll") but I’m getting <DYNAMIC LIBRARY LOAD> error.
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!
I am writing a framework for use on the Java Gateway. The role of the framework is:
1. Import the framework jar file into ensemble studio (test completed); 2. In the framework jar, handle the related functions of the remaining jar files (the rest of the jar files are written by colleagues).
The general idea is as follows:
Send: Ensemble Java Gateway -> Framework Jar -> Plugin Jar (colleagues write, processing data). Returns: Plugin Jar (processed return data) ->Framework Jar->Ensemble Java Gateway.
