The OSGi feature model specifies a concrete way of defining, assembling, and launching applications. It supports a multitude of OSGi primitives, such as bundles, configurations, and framework properties, and offers extension points for third party functionality.

Years ago, most developers would simply download Java from Sun or Oracle and deploy a monolithic application on an enterprise application server. However, things have changed, and developers now have the option to choose between multiple OpenJDK distributions and create applications or microservices using frameworks such as Spring Boot, Micronaut, or Quarkus. While all these products and tools contribute to a more diverse ecosystem, underlying standards and specifications are still shared.

In this workshop,you will get an introduction to the new and updated APIs of the Jakarta EE 10 Platform. You will get hands-on experience of the Platform with practical exercises of selected Jakarta EE 10 APIs. By the end of the workshop, you will be able to create a secure, modern, scalable application using Jakarta EE 10 technologies.The workshop requires knowledge of the Java programming language and some server-side experience, either with older versions of Java EE / Jakarta EE or comparable frameworks such as Spring.

Jakarta EE 11 will be the first release of Jakarta EE after the new release cadence was introduced. The goal is to release a version of Jakarta EE around six months after an LTS release of Java. With Java 21 released in September 2023, Jakarta EE 11 is scheduled to be released around March 2024.
What are the updates? Are there any new specifications introduced? What about removals? Will there be another namespace change? How will the impact of this release be on other frameworks and technologies, such as Spring, Apache Tomcat, Hibernate, and more?

Jakarta EE provides a comprehensive set of vendor neutral, open specifications that can be used for developing modern, cloud native Java applications from the ground up. However there are also a lot of existing applications build on top of it’s predecessors J2EE and Java EE before the specifications moved to the Eclipse Foundation.
In this session we discuss modernization pathways that make traditional Java enterprise applications more Cloud Native while preserving the existing investments. As a concrete example we’ll take a backend application running on a classic application server that provides RESTful services using Eclipse Jersey. We’ll be replatforming it to run as a serverless function on AWS Lambda with minimal code changes.

While Javascript as a language is easy to learn, node.js as a platform offers some difficulty for beginners due to its peculiar programming characteristics, and there is always few developers who have questions on the out of order I/O and its implications in the program etc.

While every software has unique ways of origination, manifestation and diagnosis of anomalies, there is a common philosophy that governs the basic building blocks of problem determination. These building blocks are composed of logical reasoning in their fundamental form, and steps that originates from such reasoning. In this session, we examine the governing principles of Java debugging and how this applies to root cause analysis of a wide speactrum of production issues, aided by case studies and real world examples.

Different platforms, different paradigms. However, workload characteristics are not derived from these paradigms, instead driven by business needs. Which one to choose for my needs? The session evaluates the comprehensiveness of programming interfaces of Java, Javascript and Python and provide insights on efficiency in terms of semantic abstraction, readability, consumability, throughput, security, footprint etc. and make useful comparative analysis.
