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.
As we all know, Caché is a great database that accomplishes lots of tasks within itself. However, what do you do when you need to access an external database? One way is to use the Caché SQL Gateway via JDBC. In this article, my goal is to answer the following questions to help you familiarize yourself with the technology and debug some common problems.
Spring Boot is the most used Java framework to create REST API and microservices. It can be used to deploy web or executable web or desktop self-contained apps, where the application and another dependencies are packaged toghether. Springboot allows you do to a lot of functions, see:
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.
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.
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'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.
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:
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 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.
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...
However, few people know what technology the agency chose for storing and processing the data collected by Gaia. Two years before the launch, in 2011, the developers were considering a number of candidates (see “Astrostatistics and Data Mining” by Luis Manuel Sarro, Laurent Eyer, William O’Mullane, Joris De Ridder, pp. 111-112):
InterSystems IRIS 2020.1 includes PEX (Production EXtension Framework) to facilitate the development of IRIS Interoperability productions with components written in Java or .NET.
Thanks to PEX, an integration developer with knowledge of Java or .NET can benefit from the power, scalability, and robustness of the InterSystems IRIS Interoperability framework and be productive in no time.
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:
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?
So, I needed to start Java Gateway, and found, that it does not want to work with the latest Java versions, I tried 20, 18, 17
Start External Language Server %Java Server:
Please wait...result will show below:
2023-07-26 19:46:24 Starting Java Gateway Server '%Java Server' 2023-07-26 19:46:24 *ERROR* Return from RunStartCmd: ERROR #5049: Java version '18.0.1.1' is not supported. 2023-07-26 19:46:25 An error occurred while trying to start the Gateway Server External Language Server failed to Start: ERROR #5049: Java version '18.0.1.1' is not supported.
Error, only says, that it will not work, and say nothing, about which version it wants to see
InterSystems IRIS includes dynamic object gateways for Java, .NET, and (now) Python. These gateways allow your IRIS application to use libraries in these languages, removing the need to create everything from scratch in ObjectScript.
Hibernate is the most popular framework to do ORM (Object Relational Mapping) projects. With Hibernate a software can use the main DBMS in the market, including the capability to change the database vendor any time, without source code impact. This is possible because the Hibernate supports dialects. Each database product has a different dialect that can be assigned into a configuration file. So, if a software is using Oracle and is looking to evolve to InterSystems IRIS, just change the configuration file with connection and dialect information.
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?
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.
All time
