DysoWeb is an OSGi-based platform that provides modularity to web applications at runtime. It uses OSGi bundles to modularize web applications and allows bundles to be dynamically installed, started, stopped and updated. This provides flexibility and dynamicity compared to traditional monolithic web applications. DysoWeb acts as a servlet filter that runs on any web container and uses an OSGi-based composition engine to combine bundles into a single modular web application. It allows standard web applications and frameworks like Struts to be modularized without any code changes.

This talk guides you through building modern web applications using ASP.NET MVC and MongoDB, one of the most popular NoSQL databases. You will learn some best practices for getting started with MVC. We’ll cover building rich-forms to accept user input. And if time permits, we might even add some client-side techniques using jQuery and MVC. All of this will be built upon the powerful non-relational database MongoDB. We will discuss the origins of the so-called NoSQL movement and why you might choose a non-relational database over SQL Server. You’ll also see our data access layer will be built using LINQ to MongoDB. Of course, you won’t be in for a night of PowerPoint. This talk is a series of interactive demos using Visual Studio 11, Windows 8, and C#.

Migration from ASP.NET MVC to ASP.NET Core

Miroslav Popovic

In its time, ASP.NET MVC has started a revolution within Microsoft, not just regarding the web application development model, but for including the third-party open source libraries which was unthinkable in Microsoft world until that point. However, it’s time to upgrade. ASP.NET is a modern multi-platform web framework built from scratch, with a similar development model to its predecessor. It marks a new revolution - Microsoft totally adopting open source. In this talk we’ll go over the advantages of the new framework, what should we care about when migrating to Core, the problems we might encounter, tips & tricks for migration process and the differences between these two platforms.

OSGi Community Event 2018 Presentation by Mark Hoffmann (Data In Motion) Abstract: This talk will show you how the EMF framework can be used in pure OSGi environments other than Equinox. We will introduce you into free configurable ResourceSets and the principle of a ResourceSetFactory. This enables your application to have multiple tenants with different model visibillity. The profit of OSGi services provides a behavior where even models can come and go all the time. We will also give you look inside, how easy it is to extend the default code generation process of EMF to generate OSGi service component that handle the model registration in an OSGi way.

OSGi and Java 9+ - BJ Hargrave (IBM)

mfrancis

OSGi Community Event 2018 Presentation by BJ Hargrave (IBM) Abstract: Java 9 introduced the Java Platform Module System (JPMS) as a way to modularize the Java platform and it can be also be used by developers to modularize their own applications, although JPMS lack a number of important features for software running on the Java platform. As people look to support the latest versions of the Java platform, changes introduced in Java 9 related to JPMS led to the needs for some features in the OSGi Core specification. OSGi framework implementations like Eclipse Equinox and Apache Felix and tools like Bnd were updated to support these new features. This session will explore the Java 9+ support added to OSGi Core R7 and Bnd and help you learn how to navigate the world of Java 9+ and OSGi.

Simplify Web UX Coding using OSGi Modularity Magic - Paul Fraser (A2Z Living)

OSGi Community Event 2018 Presentation by Paul Fraser (A2Z Living) Abstract: This talk will demonstrate how easy it is to create great web user interfaces using the OSGi Service registry and Declarative Services. OSGi has developed to the point that much can be achieved with much reduced code complexity. Forget all the past OSGi techniques and see how it can be done now. A short introduction will introduce OSGi in general and even if beginners do not fully understand the finer details of the talk, they will be amazed at what can be achieved using the OSGi service registry. Do not be frightened by the terminology, come along and experience the magic of OSGi modularity. User interfaces do not seem to get much attention in the OSGi community, it is time for a change.

OSGi for the data centre - Connecting OSGi to Kubernetes - Frank Lyaruu

mfrancis

OSGi Community Event 2018 Presentation by Frank Lyaruu Abstract: OSGi offers an excellent service discovery mechanism, it is limited to services inside the JVM. That limits us in two ways: It limits us to Java services, and it limits us to one single machine, and neither are acceptable in this day and age. Can we connect our OSGi runtime to a cluster orchestration manager like Kubernetes so our runtime can interact with the cluster and allow us to respond to changes in the cluster as dynamically as we are used to in OSGi itself. I think we can. Notes: I will show how to discover Kubernetes services (and their pods) in a cluster, and inject those as configuration objects into an OSGi runtime. That allows us to monitor the Kubernetes cluster and dynamically have our OSGi services respond to (Kubernetes) service changes. In general I hope to nudge the OSGi community to be more focused on connecting to other technologies rather than trying to stay in the OSGi walled garden. A well engineered OSGi application is perfectly suited to the dynamic nature of the cloud native world, but if we can't easily integrate with other services, well, nobody will care.

Remote Management and Monitoring of Distributed OSGi Applications - Tim Verbe...

mfrancis

OSGi Community Event 2018 Presentation by Tim Verbelen (imec) & Jan S. Rellermeyer (TU Delft) Abstract: With the proliferation of cloud computing and more recently mobile and edge computing, there is a increasing demand to build flexible and robust distributed applications. The OSGi service and module technology is a key enabler for such deployment. Recent additions to the OSGi standards provide a set of services that provide interfaces for managing distributed instances of OSGi frameworks. The REST Service (added in R6 compendium) offers an easy and language-independent way to manage bundes and introspect services from outside the network. The Cluster Information specifications (added in R7 compendium) provide means for applications to manage and monitor the deployment intrinsically, building on top of the Remote Service specifications. In the Eclipse Concierge project, we have provided the reference implementations of both specifications. In this talk, we will show how the services can be used to build distributed applications that benefit from the OSGi modularity.

OSGi with Docker - a powerful way to develop Java systems - Udo Hafermann (So...

mfrancis

OSGi Community Event 2018 Presentation by Udo Hafermann (Software AG) Abstract: In this talk we will share our experiences in developing a tool chain from classes, to bundles, to containers, to systems. OSGi and Docker come together in a compelling way where the former provides modularity "in the small" and the latter "modularity in the large". We discover how the unique characteristics of OSGi enable a smooth transition from small to large. The resulting environment enables developers to grow distributed systems on their local machine and test them with plain JUnit at all levels of granularity - classes to systems. During development OSGi enables the tool chain to update the system without container rebuilds. While an increase in productivity is one benefit of such an environment, an arguably more important benefit is the way it empowers developers to gain new insights.

A real world use case with OSGi R7 - Jurgen Albert (Data In Motion Consulting...

mfrancis

OSGi Community Event 2018 Presentation by Jurgen Albert (Data In Motion Consulting GmbH) Abstract: OSGi is often conceived as a tool to write efficient Java Applications for resource limited Devices or If resources are a real issue in complex applications. On the other hand Microservices became the buzzword of the cloud and is often implemented using Spring or other Programming languages. OSGi carries the concept of microservices in its core and is therefore much better suited to the task then most other approaches. This talk will show you how a service can be built with a real-worldish use case, leveraging the power of OSGi R7. It will show the combined usage of PushsStreams, the JaxRS Whiteboard, the configurator, remote deployment and a lot of the other cool things OSGi has to offer.

OSGi Feature Model - Where Art Thou - David Bosschaert (Adobe)

mfrancis

OSGi Community Event 2018 Presentation by David Bosschaert (Adobe) Abstract: OSGi lends itself well to develop extensible applications assembled from reusable modules, where a set of bundles together with a set of configurations deployed to a provisioned OSGi framework is the application. While this works very well for the originally intended use-cases, maintaining and building large applications developed by multiple teams often requires to assemble multiple larger components for which there is limited support in OSGi as of today. This is especially true in cases where multiple groups of bundles, configuration, metadata, and other artifacts need to be combined. In this talk we will introduce you to OSGi RFP-188, named OSGi Features, which defines the requirements on providing a solution. We'll establish a shared understanding of the problem space and how it relates to already available mechanisms in OSGi (like e.g. subsystems, deploymentadmin, startlevels, etc.) and will subsequently, review it in the context of some of the current (open source) solutions like Apache Karaf Features and Apache Sling Features and Bnd.

Migrating from PDE to Bndtools in Practice - Amit Kumar Mondal (Deutsche Tele...

mfrancis

OSGi Community Event 2018 Presentation by Amit Kumar Mondal (Deutsche Telekom AG) & Jochen Hiller (Deutsche Telekom AG) Abstract: QIVICON is an Eclipse SmartHome based solution from Deutsche Telekom AG. It utilises OSGi to provide a modular Java runtime. Since the beginning, QIVICON leveraged Eclipse PDE with Maven & Eclipse Tycho as its build technology but over the time, the complexity increased. It became hard to get an overview and manage the runtime and build dependencies. Especially maintaining target configurations for IDE and CI/CD build, having different embedded gateways for installation increased complexity significantly. Bndtools is the 'swiss army knife' in the context of OSGi development since it takes the nitty-gritty pains and loads off the developer's chest. And that's why we decided to avail the benefits of Bndtools. But, many other OSGi-based projects still cannot avail the benefits as they are very tightly coupled with Eclipse PDE. Want to make a switch from your existing PDE source base to Bndtools? This talk would give you an overview to proceed towards this. We would like to further demonstrate in this talk how to set up a Bndtools workspace from an existing PDE workspace, convert all current projects to Bnd projects and embrace the OSGi-way of developing bundles. Since QIVICON containing more than 350 projects utilised this solution to move to a higher modularity maturity level, this talk would, therefore, outline the pros, cons and the learnings using Bndtools in such a big OSGi project for embedded development.

How OSGi drives cross-sector energy management - Jörn Tümmler (SMA Solar Tech...

mfrancis

OSGi Community Event 2018 Presentation by Jörn Tümmler (SMA Solar Technology) Abstract: SMA is a leading global specialist in photovoltaic system technology with more than 3,000 SMA employees in 20 countries. In 2015 SMA decided to develop the ennexOS platform - a cross-sector platform for holistic, intelligent energy management. An important part of this platform is the data-manager - an IoT gateway that acquires information from various energy generators, storages and loads and performs commissioning and management tasks. This new generation of data-managers demanded for new approaches in software-architecture to: run on a broad range of hardware platforms, and be extendible e.g. to support different protocols for easy integration, and to enable a broad range of applications in the energy-management field that may be customized by apps installed during runtime After an exhaustive investigation on existing solutions, OSGi was chosen as the key technology for this new generation of devices - a quite challenging decision, because at this point there was only limited experience in Java and OSGi development in the company. This talk will present the key factors that lead to this decision, how we very carefully build up Java and OSGi knowledge, and started with an initial design. OSGi enRoute and the support of OSGi experts helped us to accelerate our development and become familiar with OSGi - although we also had times when we were struggling because of the new technology. The talk will demonstrate what we have reached until now and we will tell you if OSGi has kept it's promise ...

mfrancis

OSGi Community Event 2018 Presentation by Lukasz Dywicki (Code-House) Abstract: During this short presentation I will revisit existing mechanisms and approach towards OSGi and JEE development. I will show how many manual steps can be avoided and how to maintain project in effective manner. I will try to find a balance between execution environment requirements and programmer happines at same time. I believe that OSGi and Eclipse ecosystem experience troubles gaining people from outside for few reasons. Beside overall impression of OSGi complexity there is equally old and invalid complain about quaility of developer tooling. Since invention of BND development experience can be really pleasant and independent of text editor/IDE preferences. Sadly lots of people still rely on former experiences spreading black/bad PR. I would like to clarify their point. After this presentation attendees will learn: How to use Maven to build OSGi projects (without Tycho). How to automate manual tasks. How to build custom software distributions with Maven artifacts and run it with Apache Karaf. That OSGi development doesn't differ much from regular day-to-day usage of application servers or microservice runtimes. This talk is intended for people who know basics of OSGi as it will show few basic technics towards better developer productivity.

This talk will present how the OSGi specifications have evolved over the years, and how you today, in 2018, design an OSGi based Smart Home System. A real world use case of a Swedish Smart Home start-up company will be used to illustrate different design principles and how OSGi remains as relevant today as it was when it started.

Popular patterns revisited on OSGi - Christian Schneider (Adobe)

mfrancis

OSGi Community Event 2018 Presentation by Christian Schneider (Adobe) Abstract: We will look at common cloud and design patterns and see how the special properties of the OSGi environment allows us to rethink these patterns. The talk shows some well known patterns like the service registry and the whiteboard but also some unique patterns like out of band circuit breaker or graceful degregation. The patterns are shown with some examples using declarative services(DS). So some basic OSGi and DS knowledge is of advantage but not required. For OSGi beginners the well established OSGi patterns will help getting started the right way. Experienced OSGi developers will find some new patterns to think about. Cloud or enterprise developers will get a new approach to some patterns they are used to which hopefully inspires them to take another look at the current state of OSGi.

Integrating SLF4J and the new OSGi LogService 1.4 - BJ Hargrave (IBM)

mfrancis

OSGi Community Event 2018 Presentation by BJ Hargrave (IBM) Abstract: OSGi Compendium R7 provides a major update to the OSGi LogService specification. A new logging API is added which supports logging levels and dynamic logging administration. A new Push Stream-based means of receiving log entries is also added. But it is quite often the case you need to use other code such as open source projects which are using slf4j for their logging API. This session will explore the new OSGi LogService changes and how you can integrate code using both slf4j logging and OSGi LogService logging.

OSG(a)i: because AI needs a runtime - Tim Verbelen (imec)

mfrancis

OSGi Community Event 2018 Presentation by Tim Verbelen (imec) Abstract: Nowadays AI is reaching new heights on the hype cycle, especially due to recent advances in deep learning techniques. A lot of deep learning frameworks exist for creating and training deep neural networks, the most popular ones being PyTorch and TensorFlow. However, how to integrate, deploy and manage these neural networks in complex software systems is often overlooked. In this talk we show how OSGi can be used as a modular runtime for deep learning models. We embed those models inside OSGi bundles, and use the extender pattern to make these available as OSGi services. You can then use your favorite OSGi specs such as DS and PushStreams to integrate these into your application.

Flying to Jupiter with OSGi - Tony Walsh (ESA) & Hristo Indzhov (Telespazio V...

mfrancis

OSGi Community Event 2018 Presentation by Tony Walsh (ESA) & Hristo Indzhov (Telespazio Vega) Abstract: The European Space Operations Centre (ESOC) is the main operations center for the European Space Agency (ESA), operating a number of earth observation and scientific missions. Monitoring and control functions needed by spacecraft operators are provided by software systems which are reused across missions, but tailored and extended for mission specific needs. The current generation of monitoring and control systems are becoming obsolete and a European wide initiative called the European Ground Systems Common Core (EGS-CC) (http://www.egscc.esa.int) has been started to develop the next generation. This talk will explain why OSGi was chosen and how it is used in the development of next generation of monitoring and control software. It will describe how OSGi provides the necessary framework that enables the software to be extended for the different space systems it is expected to support. The overall software architecture will be discussed, some of the challenges faced and the benefits gained by using OSGi. The first target mission for the system is JUICE (http://sci.esa.int/juice) which will explore the moons of Jupiter and which is scheduled for launch in 2022.

Prototyping IoT systems with a hybrid OSGi & Node-RED platform - Bruce Jackso...

mfrancis

OSGi Community Event 2018 Presentation by Bruce Jackson (Myriad) Abstract: Node-RED is often used as a protyping tool for IoT systems. However, there are also a large number of OSGi components that have already been built to interface to devices, sensors and systems. In this talk I will show how two completely different runtime environments (OSGi and Node-RED) can be combined into a single platform for prototyping (and more) combining the strengths of both languages and systems. Being able to quickly and simply prototype IoT application is extremely useful, and to this end many people have adopted Node-Red, a Node.js based runtime with extensive support for plugins to interface to various IoT hardware and protocols. However, this requires these services/protocols to be developed in Javascript, and there is already a significant body of code developed in Java/OSGi that it would be desirable to re-use. The talk will explain how it is possible to: Create and manage a Node-Red runtime from within an OSGi bundle  Share OSGi components and object into the Node-Red runtime  Interact and build Node-Red flows that exchange data and call methods between Node.js and OSGi This is obviously useful for the original purpose: prototyping IoT systems, but also demonstrates some interesting techniques for bridging between different languages and runtimes.

How to connect your OSGi application - Dirk Fauth (Bosch)

mfrancis

OSGi Community Event 2018 Presentation by Dirk Fauth (Bosch) Abstract: In todays connected world the requirement to connect applications across network boundaries has become a common requirement. With OSGi there are several ways to accomplish this, as there are different specifications to achieve this. In this talk we will look at some of these specifications to show what options there are and which might fit your requirements. Starting from an architecture that makes use of the HTTP Whiteboard pattern, over Remote Services to finally showing the usage of the JAX-RS Whiteboard specification introduced with R7. We will show the general usage of these specifications and explaining the advantages and disadvantages of each solution.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery.
