Open Services Cloud: Unleash the power of self-operated cloud managed services

Jean-Baptiste Onofré (Huawei Technologies Co., LTD.)

Today, from core infrastructure to advanced machine learning services, managed services are the
key capabilities and value that clouds offer to their customers. However, only cloud service
providers have the ability to offer managed services. Software providers are locked out from
creating native managed services in clouds, and users are locked in to proprietary managed
services from cloud service providers. As a result, software providers must compete against their
cloud service providers’ own managed services with limited cloud software images or SaaS

Realizing the Potential of Cloud Native Serverless Jakarta EE

Steve Millidge (Payara Services Limited)

Many myths and misconceptions surround the concept of ‘serverless.’ It’s the latest industry buzzword - but what does it mean, and how does it apply to Jakarta EE?

In this talk, Payara Services CEO and Founder Steve Millidge will give a demonstration of what serverless can look like in a Jakarta EE environment.

Langium + Sirius Web = <3

Axel RICHARD (OBEO)

Théo Giraudet (OBEO)

Langium is an open-source project which proposes an alternative to Xtext in the NodeJS platform. Developed around LSP (Language Server Protocol), Langium is therefore totally front-end technology agnostic as long as the front-end supports the protocol. The goal of this talk is to show how we went from no knowledge of Langium to a prototype integrated in the Eclipse Sirius Web infrastructure and applied to a subset of SysML v2. SysML v2 being the newest version still under specification of SysML, a textual and graphical modeling language for system engineering.

Jakarta EE Security - Sailing Safe in Troubled Waters

Werner Keil (Self Employed)

Ivar Grimstad (Eclipse Foundation)

Security in Jakarta EE has long been under-used and under-specified. Existing specifications ranged from overly complex to non-existent. The result: few people used security standards. Java EE 8 changed that with JSR 375. Its evolution Jakarta Security facilitates portable application security integrated with container security. Allowing applications to treat authentication mechanisms like OAuth or OpenID Connect same as built-in container mechanisms like FORM or container-based access to a URL and features like @RolesAllowed and isUserInRole automatically work as expected.

Deploy and update Jakarta EE & MicroProfile applications at light speed with Paketo

Jamie Coleman (IBM)

More developers are using Polyglot programming models with their application architecture and why should they not use the language that makes sense for a specific task. This is where we introduce Paketo, the open-source tool that enables a developer to automatically detect what language they are using and build a runnable container image with that application and a runtime to run said application.

What's new in JSON-B and Yasson

David Kral (Oracle)

I will introduce the new features of the JSON-B 3.0.0 and will do the live-coding demonstration of how to use any of these features. There is possibly just one minor requirement for my attendees to know what JSON is.

Make your Java application observable with no code changes using OpenTelemetry

GianMaria Romanato

Renato Bertacco (work for SIAV)

Microservice architecture comes with many benefits but implies additional complexity especially in the context of deployment, monitoring and observability.

Containerization of performance testing

Soumya Biradar

If we use identical containers in every environment, there won’t be any differences across dev and test environments, This increases developer velocity and helps deliver code faster. Containers provide short time environment to run your tests, making sure your tests run in isolation and don't interfere with one another. You can simplify the evolution of your application just by deploying a new version with a new image. In this session we will talk how docker containerized performance testing help us achieving the benefits listed here over local test environment.
