#Java

Hi people,

I am migration my web application of Cache 2013 to Cache 2016, in Cache 2013 I have a integration with a Java aplication using Java Gateway mapping proxy classes and consuming a method that param is a object, and it works perfectly.

But in Cache 2016 this integration don't work, I send the param as object but Cache send as String with the ref of object...

The InterSystems documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls... says: "If you do not already have these files, contact the InterSystems Worldwide Response Center (WRC) for download information."

I know there are numerous Java libraries available to scan a PDF meta data, but is there a way to scan a PDF using native cache object script? We are looking to take a PDF from an external vendor, scan for meta data, create the HL7 message, and embed the PDF within the HL7 message.

Thanks

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?

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 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:

Hi Cache team, I am in the need of listing all the user defined schemas that are present my Cache db and also the user defined tables and views and Columns of those tables and views through Queries. So that I can write some JDBC code to run the queries and fetch the above metadata. Any help is appreciated.

Thanks in Advance,

Kranthi kiran.

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!

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.

Problems encountered with Java Gateway

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.

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". 🙂

In an Ensemble 2016.2 production, I put a JavaGateway service. How do you get the console output?

I set the JVM service as Foreground but I don't see any output from Java.

Thanks,

Blaise

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

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.
