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.
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.
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?

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:
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.
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.
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'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".
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).
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:
A new Health Connect customer has a few experienced Java folks on their interface team. As they get more into Health Connect and learn Caché ObjectScript they thought it would be useful to have a list of common Java statements with an equivalent statement in ObjectScript. They mentioned string manipulation as an example, but would be interested in other areas as well.
This seems like something that is probably already floating around somewhere. Does anyone have something like this or other "COS jumpstart for Java devs" materials?
I fire a call of COS method through Java gateway and get the return value whose type is %Status in COS.
What is the corresponding class for %Status in Java side? Any existing utility to help me parse this object so I could know this COS call finish with errors or not.
I'm trying to authenticate a user(Health Share clinician) from a Java Application.
I 'm already connected to Caché and able to run SQL commands.
My question is: How can I authenticate a user using only SQL? In fact, what I want is verify if the users exists in the base and if the given password is the same used in Health Share.
There is a column 'password' in Security.users table but I'm not able to see its content, even so, I don't know which hash function to use to compare with.
