Many times it is necessary copy or send files to your docker container instance.

In my case was with IRIS JDBC driver.

Docker has this recipe for this (credits to https://docs.docker.com/engine/reference/commandline/cp/):

docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH

But to copy you need your container name. Write this command for this:

docker ps

In my, my-iris is the container name.

If you need to know file location into your docker file system too, write:

Hi Community!

This week is a voting week for the InterSystems IRIS Native API Programming Contest! We have 8 applications — so you have a set of applications to choose from!

How to vote? This is easy: you will have one vote, and your vote goes either in Experts Nomination or in Community Nomination.

Hi All,

I am writing this article to tell about the application "CRUD-GLOBALS-IRISNATIVEAPI-JAVA" which is developed as part of "InterSystems IRIS Native API programming contest". The intention of this application is to manage the Globals which are in IRIS instance through java program using IRIS Native API. To use this application basic knowledge of CACHE Globals structure is required.

In this application as of now we  have options to Create,View  Globals and Data Search in Globals. Update and Delete will be added in next releases.

The contest will last three weeks: May 18 – June 7, 2020. 

I am using the Java Binding to connect a Java Middleware Application to Cache.  Originally I was using a CacheListOfDataTypes (JAVATYPE = "java.lang.List") object to bring data back.  I was tasked with encrypting the data using AES and I was using the AESCBCEncrypt function on the List elements (up to 20k characters for each element) to bring it back before concatenating it on the middleware.  This almost worked.  Like 95% of the characters were being decrypted correctly but some text was coming back garbled.  I couldn't understand how this was happening. I tried to adjust things like the

Hi Community!

We are using Ensemble 2018.1.3.

I am trying to import the org.apache.poi jar file (I have same problem with 3.8, 4.0.1, and 4.1.2).

Whenever I try to import the org.apache.poi.hssf.usermodel.HSSFWorkbook class using the Java Gateway Wizard, I get an XML error such as the following: 

ERROR #6301: SAX XML Parser Error: Line: 215 Offset: 20 invalid character 0x5 while processing /hs-connect/sys/mgr/Temp/mMQ5qDvObKsxaw.xml at line 215 offset 201

In doing some digging, it looks like the problem is in the org.apache.poi.POIDocument.class because it has the following code in it:

I’m excited to announce that InterSystems will be joining the open source community for InterSystems ObjectScript extension to Visual Studio Code. Early this year I posted that we were on a journey to redefine the future of our IDE strategy, and what came out of that is Visual Studio Code is the IDE that can support that future. It’s fast, stable, feature-rich, and built on a modern technology architecture that affords us the ability to offer you far more functionality around your ObjectScript activities than ever before, particularly in the area of DevOps, continuous development, and

Hi All, 

I am trying to add pdfbox-2.0.18.jar file into Ensemble and getting below error but with pdfbox-1.x it's working fine. So can anybody please assist me to do fix below issue as showing in screen shot.

Thanks,

Hi

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...

Does anyone have any experience in this area?

I'm working on developing Productions with java. The sample project has several intersystems jar files: -- intersystems-enslib-jms-3.1.0.jar -- intersystems-gateway-3.1.0.jar -- intersystems-jdbc-3.1.0.jar -- intersystems-spark-1.0.0.jar -- intersystems-uima-1.0.0.jar -- intersystems-utils-3.1.0.jar -- intersystems-xep-3.1.0.jar

I have the jar files, but where can I find them for download? Are they available on a maven repository somewhere?

Any help would be appreciated!

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

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.

Hello community,

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.

Hi All,

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

Property PetName As %Integer(DISPLAYLIST = ",Cat,Dog,Dove,Parrot", VALUELIST = ",1,2,3,4");

Java Code:

public String PetName;

public List<Pet> getPet() {
        return ser.findAll();
    }

List<Pet> arrayList = getPet();
        for (Patient list : arrayList) {

                 String pet= list.getPet();

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.

As of now I am attempting to get this to work on a local environment.

Hi all...

I am try to execute a class method from JDBC connection. My method are simple, just create a file at $HOME  like this:

set sc='$zf(-1,"touch $HOME/lixo.txt > /var/tmp/log666 2>&1")

I put a log file to this commnad because it's don't work, and in log file i get this:

touch: cannot touch ‘/root/lixo.txt’: Permission denied

after to try other commands I found that user and enviromnent  variables are diferents:
I try this:

set sc='$zf(-1,"echo $USER > /var/tmp/log666 2>&1") ;Return root

set sc='$zf(-1,"echo $HOME > /var/tmp/log666 2>&1") ;return /root

Hi all....

I couldn't find documentation on how to create a blob using the cache JDBC driver.
I found only one reading example:

https://cedocs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?…

The createBlob Method of the connection class was not implemented:

https://cedocs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?…
 

Does anyone know how to create a blob without compromising the java heap space?

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.

Atelier: 1.3

Eclipse: 4.11.0

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 everyone, 

I have just started to use JavaGateway and I didn''t encountered so much difficulties since I've got the output of the Java class I have called. 

This is the class I have implemented: 

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 Everyone!

New video, recorded by @Stefan Wittmann, is already on InterSystems Developers YouTube:

SQL and Object Access

 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:

package isc.rabbitmq;
public class API {
    public void sendMessage(byte[] msg) throws Exception {}
}

On the InterSystems IRIS side I'm calling it like this:

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. I've tested the same query using a local IRIS

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 similar advice on how to achieve this thanks in advance

Hi everyone,

Im new  in cache, i came from Java and im missing some features that i couldn't find in the documentation,  I hope you can help me with this questions.

Just a brief introducction: 

- Im in a project with old cache version, so saddly i can't use Eclipse + Atelier, so im using Studio.

- Currently im in a project with persistent classes, we want to turn apart the globals and focus on tables. 

The questions:

Hi All,

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.
