java-8 | code base has all the code | Generator Utils library

I am using websphere-liberty(https://hub.docker.com/_/websphere-liberty/) image to deploy my apps but I have problems with shared libraries. I need to transform jar from util project into shared libraries on liberty server. Im stuck on this error:

SchedulerApplication- loaded ok - is from Scheduler app but it is extending class from util project

I want to execute N tasks in parallel such that no individual task should run for more than 2 seconds (we can mark such tasks as failed). As an output i want to return output of successful tasks and status of failed tasks as failed. Also timeout of 1 task should not lead to circuit break, i.e other tasks execution should not stop.

NOTE: I am restricted to use JAVA 8.

I referenced this article for parallel processing. I am doing similar kind of parallel processing as given in example in this article:

I'm using docker-compose to launch a commandbox lucee container and a mysql contianer.

I'd like to change the web root of the lucee server, to keep all my non-public files hidden (server.json etc, cfmigrations resources folder)

I've followed the docs and updated my server.json https://commandbox.ortusbooks.com/embedded-server/server.json/packaging-your-server

I have a tiny on premises Spark 3.2.0 cluster, with one machine being master, and another 2 being slaves. The cluster is deployed on "bare metal" and everything works fine when I run pyspark from the master machine.

The problem happens when I try to run anything from another machine. Here is my code:

Yoo coderrs, have problem connect and write table to my online free database. Problem is hereUnable to create requested service and Unable to make JDBC Connection

My Java-8 project is build using spring-boot 1.3.6 version, Which by default inherit 'log4j-core-2.4.1', but now I want to upgrade log4j-core to 2.17.1 for which I added 2.17.1 into pom.xml file of my project. The build runs fine but the error says:-

I have a spring-boot application with mysql database connection and junit test classes. That's working fine in local machine. But when I pushed the code to Gitlab to build a CI/CD pipeline, the build stage is failing due to mysql connection issue.

When I am trying to save an entity into the DB I get the following error and I don't where the mistake could be. I am using only LocalDate. I have an example of entity below.

I prefer all times to be in UTC, except for when they are displayed. At the last moment, they can be converted to a local time for display only.

I've always stored unix timestamps (seconds since epoch) in MySQL before, in an integer field. I'm working with someone else's database schema that I cannot change which uses a DATETIME that stores a raw time without even an offset.

How can I retrieve and send time objects with the database in UTC, so the database is doing absolutely no conversions whatsoever?

Although written for PostgreSQL, I've tried to follow the excellent answers by Basil Bourque on the questions below. I use Instant everywhere, except as he shows I use an OffsetDateTime when interacting with JDBC, because it's the only modern moment class guaranteed to be supported by JDBC 4.2.

• How to convert UTC date to UTC OffsetDateTime in java 8?
• Issue in saving current date with UTC time in sql server
• and How to save correct date time with timezone when using jdbc

I'm using MySql Connector/J 8.0.27, and am connecting with &preserveInstants=false&connectionTimeZone=UTC.

Let's look at a DATETIME in the database stored as "2022-01-14 11:00:00" which is understood to be UTC.
