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 .

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:

Is there any way to make something like hibernate for cache %Persistent classes?

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.

My Java wrapper class has a constructor like this:

According to the documentation this should be called with %GlobalCharacterStream arguments from the IRIS side.

I successfully got everything in this guide to work:  https://community.intersystems.com/post/ensemble-rabbitmq-java-client-q…

I am now using the information I gained from this guide along side with this guide:

https://www.rabbitmq.com/tutorials/tutorial-one-spring-amqp.html

I am running into an issue though. In the RabbitMQ guide I just posted, they have a "Receive message" functionality. I use that alongside with the SendMsg from Ensemble method in the InterSystems guide.

InterSystems has completed the verification process for OpenJDK 8.

Customers now have the option to either use the Oracle JDK, or the OpenJDK with all InterSystems products and versions that support Java 8.
 
Support for future versions will continue to be supported on both of these Java Development Kits.

Intro

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.

Hi

Totally new to IRIS and Cache.

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?

2) Can we import an existing Cache database into IRIS and convert its ObjectScript code into Java, Python whatever?

Hi,

I ran into the Issue https://hibernate.atlassian.net/browse/HHH-10620. The workaround  described at https://community.intersystems.com/post/support-java-hibernate-5 worked for me. I'm using Hibernate Version 5.3.2.Final.

It would be nice if someone from InterSystems could fix the the problem in Hibernate. That was mentioned in https://community.intersystems.com/post/support-java-hibernate-5 but it doesn't seem to have happened.

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 projects uses Hibernate 5.

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.

Hello,

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 want to call java method and return $lb structure from it.

JDBC jar seems to contain relevant class -  com.intersys.jdbc.CacheListBuilder, but so far I only managed to return a string that looks like a list.

Here's my java code:

package isc.poi;

import com.intersys.jdbc.CacheListBuilder;
import java.sql.SQLException;

public class Test {

    public static String Test() throws SQLException
    {
        CacheListBuilder list = new CacheListBuilder("UTF8");
        list.set(123);
        list.set(456);
        list.set("\"abc\"");

        return list.

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!

Hello Global masters!

I developed Web with Spring framework (JAVA, Jdbc Cache) and I wrote SQL when I made it.

And Window program with VB6, Cache Object and VisM.

Is there a significant performance gap? SQL and Cache Object?

same function, same computer performance just different Java and VB6.

Thank you.

Minsu.

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.

Hi-

I have searched through documentation, etc and see many mentions of using Ensemble / Health Connect along with the Java Gateway to interface with JMS Queues, but see no specific documentation on how to do this.

Does anyone have any information, or a concise example of using the Java Gateway to allow Ensemble / Health Connect to be able to place messages and retrieve messages from a JMS Queue?

Thanks

Hi, Community!

Hello I'm Minsu

I want to develop web program like community with Spring Framework and Caché. but I have experience only with MySQL.

A. Can I use Caché with Spring Framework?
B. If I can, How? 

Thank you guys.

I defined the variables in Cache, as follows:

Property Content As% Stream.GlobalCharacter [Required, SqlColumnNumber = 3, SqlFieldName = B_Content];

And then use the SQL statement to add:

insert into table_name (B_Content) values ('very long string');

But the error:

 org.springframework.http.converter.HttpMessageNotWritableException: Could not write content: No serializer found for class com.intersys.jdbc.CacheInputStream and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com .sxxxx.jdbc.datastore.

Trying to connect Ensemble to RabbitMQ following this article I'm using Java Gateway and encountered the following problem - in all my calls I need to pass connection object, which is always the same but it takes a long time to create. Here's java code:

package com.myorgname.rabbitmq;

import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports.  We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down.  We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page.  I am new to Cache so any help would be greatly appreciated.

Also, is there an easier solution to this print all problem?

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

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...

I maked a test, importing two classes used by the Java Gateway (%Net.Remote.Proxy and %Net.Remote.

Hi,

I have a stored procedure which would generate a standard Cache String and it would be called through JDBC and I would

dump the result in java console/standard output.

What kind of characters should I use in COS so when output get send back to Java side, it knows it contains new line character ?

Thank for your help.

Hi!

                  I'm using Caché JDBC driver to store, retrieve and some other operations. I have another question, "Is there any possible to execute the cache commands using JAVA".

Thanks

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

Short question: Why are (almost) all Java-Classes marked as deprecated? I never had any problems. And the docu for java-bindings are still (version 2016.2.1) not marked as deprecated. I ask, because in my case everything works and the writing of Unittests is easier than in Objectscript and i cannot find a note about the reason of the deprecation (at least in the classes i have checked).

Recently we have exercised this with a partner. It may be helpful for others as well.

The basic functionality is to connect to SAP through SAPJCo (Supporting SAPJCo 3.07+).

As a first step have a production with at least two items of the following type:

• EnsLib.JavaGateway.Service
• EnsLib.SAP.Operation

Configure the settings for the Java Gateway and the SAP Operation accordingly. And start the production.

Now the library sapjco3.jar needs to get imported to be used by further internal functionality.

Internally we use splunk for monitoring applications and network.

Does Ensemble have a way of exposing internal metrics and/or a way of exposing custom built metrics? 

I've used Deepsee dashboards in the past to monitor Apache Tomcat/Apache Camel/hawtio using JMX rest calls. This is the other way around and ideally I'd like to expose metrics on:

• HL7v2 messages (broken down into types)
• Production performance
• Error and Warning.

Understand Ensemble 2016.2 includes Java 8 JVM and was wondering if the JMX route (plus hawtio) is the way to do this?
