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.
I have a spring-boot Java application which has Quartz Scheduler (spring-boot-quartz-starter) dependency, and uses IRIS DB. There is a problem with making Quartz Scheduler work with IRIS since there is a blob field expected in two tables, but IRIS is using longvarbinary type. Can you provide me with clues on how to resolve this?
I am using org.quartz.impl.jdbcjobstore.StdJDBCDelegate driverDelegateClass.
This is the error: MisfireHandler: Error handling misfires: Couldn't retrieve trigger: invalid stream header: 41434544
For example, I have two timestamp values ('2024-04-01 10:00:00', '2024-04-01 11:30:30'). I would like to find the difference between these two timestamps, and I need the result in hours:minutes:seconds (hh:mm:ss) format.
Expected Output: 01:30:30
Note: I need an SQL query command. I should not use ClassMethod, Function, or Stored Procedure.
Could anyone please provide me with an SQL query for my question?
Once again I would like to know, if there are any plans to make Java libraries available through normal channels like public mvnrepository, like the whole world it's doing, where anyone can find any JDBC driver to any database in the world but InterSystems.
Currently there is only some useless garbage. There are just very empty files. What was the point of posting it there?
Has anyone noticed that when IRIS is forced down that the EnsLib.JavaGateway.Services do not properly shut down and release the ports? While we can write a shell script to kill the processes at the OS level, I was wondering if anyone experienced this issue.
We are working on our Mirroring setup/failover and had the team testing forcing the Primary down to make the Backup to become the Primary Server. When this happened and we failed back, IRIS could not restart the JavaGateway.Services because the ports were still in use.
A few months ago, I faced a significant challenge: streamlining the handling of business logic in our application. My goal was to extract the business logic from the code and hand it over to analysts. Dealing with a multitude of rules could easily result in a code littered with countless "if" statements, especially if the coder lacked an understanding of cyclomatic complexity. Such code becomes a source of pain for those working with it—difficult to write, test, and develop.
This article aims to explore how the FHIR-PEX system operates and was developed, leveraging the capabilities of InterSystems IRIS.
Streamlining the identification and processing of medical examinations in clinical diagnostic centers, our system aims to enhance the efficiency and accuracy of healthcare workflows. By integrating FHIR standards with InterSystems IRIS database Java-PEX, the system help healthcare professionals with validation and routing capabilities, ultimately contributing to improved decision-making and patient care.
The new $system.external interface (aka "InterSystems External Servers") is used to call/integrate with external language code/libraries, it replace the old gateways (for example Java gateway) that required the import of proxy objects.
Note that the documentation for the old gateways has been removed from IRIS, so only the new $system.external interface is somewhat (i.e. insufficiently) documented.
Regarding the migration from old gateway to new $system.external interface the documentation says:
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.
The motivation behind the InterLang project is rooted in the innovative integration of LangChain chatbot agents with the Fast Healthcare Interoperability Resources (FHIR) framework to revolutionize conversational social prescriptions in healthcare. This project aims to leverage the rich and standardized data available through FHIR, an emerging standard in healthcare data exchange, to inform and empower these advanced chatbot agents.
In a fast-paced digital era, effective communication is crucial. This article introduces a Java-based chat project, combining the strength of IRIS database and ChatGPT intelligence. Built on Java, it goes beyond real-time messaging, leveraging IRIS and ChatGPT for an enhanced chat experience. Also, the name of the project references the cultural classic - Star Wars.
My newest app includes a java routine to read data from Excel 95, 97, 2000, XP, and 2003 workbooks and write the data into IRIS globals using Java Native API library.
If you have Git and Docker installed, clone/git pull the repo into any local directory
Maven is a tool, hosted by the Apache Software Foundation, for building and managing any Java-based project. Apache Maven is the best source of information.
In our previous post, we discussed the motivation for developing a chatbot agent with access to FHIR resources. In this post, we will dive into the high-level design aspects of integrating a Streamlit-based chat interface with a Java SpringBoot backend, and enabling a LangChain agent with access to FHIR (Fast Healthcare Interoperability Resources) via APIs.
GmOwl is a solution that offers an organized and engaging learning platform. It was developed to cater to the increasing need, for learning tools providing a versatile quiz environment that meets users requirements.
The main objective of GmOwl is to deliver an user experience for individuals participating in quizzes while giving administrators comprehensive control, over content and user engagement.
GmOwl uses Java EE with MVC template, and the InterSystems IRIS database is used to store data. The InterSystems JDBC Driver is used to connect to the database.
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". 🙂
There are situations when your only access to a server is using a web browser, and there is just no chance of a Terminal or Console access. The Online Demo Server is such a case.
So you have WebTerminal. That's fine for ObjectScript and Embedded Python.
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.
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.
