📍Inside Jmix 2.8 ✨SidePanelLayout A container for displaying a sidebar (also known as a Drawer). It’s useful when you need to show contextual information alongside the main content: viewing details, editing an entity, applying filters, performing actions, or working with forms - all without switching to another screen or opening a dialog. Its advantage is that it keeps the user focused within a single workspace, reduces the number of user actions, and makes the interface faster and cleaner.👍 Due to its panel positioning, overlay/modal modes, and simple open/close control, the component easily adapts to various UX tasks.

💧 From infrastructure data to smarter water management Engineering company Altereo (France) works closely with water utilities that manage large and complex infrastructure networks. Water networks generate large volumes of heterogeneous data — from asset inventories and inspection records to maintenance plans and geographic information. Making this data accessible, structured, and useful for daily operations and long-term planning can be a major challenge. ⚡ Today, Altereo operates 20 offices across mainland France and Réunion, with an additional office in Côte d’Ivoire, supporting water utilities and infrastructure projects across multiple regions. To analyze water network data and optimize maintenance planning, Altereo developed a specialized platform, ID BAC, built in Kotlin with the use of Jmix. The platform helps manage infrastructure data efficiently and supports better decision-making for water utilities. 🚀 Curious how the project came together?

Starting a new enterprise project from scratch is still hard. 🧐 “But AI agents already solved this.” 💢 Yes — for prototypes, experiments, and personal projects, that’s true. You can generate a working app in minutes. But when we talk about enterprise-grade systems, the challenge is still very real. In real projects you still need: 📍A well-structured domain model 📍Clear architecture boundaries 📍Role-based security 📍Upgrade-safe customization 📍Predictable scalability 📍Maintainable codebase AI can generate code. But it doesn’t automatically give you a production-ready structure. And this is where starting from zero is still expensive: ✏️ How should I structure the project? ✏️ Am I designing it correctly? ✏️ How do I avoid long-term technical debt? ✏️ How much time will I spend writing typical model classes again? We know this feeling. That’s why we created a B2B CRM sample application for Jmix — one of the most common real-world use cases. The goal is simple: Reduce the effort and uncertainty of the first serious step. You can: ✅ Show it to your partners as a production-ready example. ✅ Clone it and build your own solution on top. ✅ Use it as a structured template. ✅ Or even feed it to your AI agent to generate something new based on a solid architecture. Most importantly — it’s available for everyone, free of charge: 👉 Live demo: eu1.hubs.ly/H0sHQrm0 👉 Source code on GitHub: eu1.hubs.ly/H0sHR5Y0 Enterprise systems still require structure. Start with one that’s already designed properly. If you find issues or want to suggest improvements — please use GitHub Issues so nothing gets lost. And share your impressions in the comments 👇

📍Inside Jmix 2.8. Data Model Visualization When you’re writing a report and thinking: “Okay… but how exactly are these entities related?” When working with Reports, you often need to look at the ER model: 📍what relationships exist? 📍where it’s OneToMany? 📍where it suddenly turns out to be ManyToMany? What do you usually have to do to see the necessary information about the data model? 1) Open pgAdmin or DBeaver (assuming they’re already installed). 2) Run the required queries or search for the information in the UI. While looking at one thing, you forget about another: you switch back to the application or the code, lose focus, lose context…🔄 Starting with Jmix 2.8, there’s a more convenient way with the DataTools add-on. Data Model Visualization ✨ The DataTools add-on now makes it possible to see all entities and their attributes on a single screen, as well as generate a detailed ER-diagram. Just a couple of clicks — and all the information you need is right inside your application. No unnecessary switching or extra tools 👌🏼

📍Inside Jmix 2.8. Additional Message Bundles. 🌍 Multilanguage support is one of the core features of enterprise applications. As a project grows, message management becomes a discipline of its own: more modules → more entities → more screens → more messages → localization files grow and start to look intimidating 😅 Even if a project has naming conventions and rules for key placement, it’s still easy to get lost in a huge amount of text. That’s where additional message bundles become a great solution. Since Jmix 2.8, Studio provides better support for additional bundles: they are visible directly in the Jmix tree, and the localized message editor allows you to switch between bundles easily 🔁 Less chaos in eu1.hubs.ly/H0sxrv_0. More structure and clarity in your projects ✨

If you've heard of Domain-Driven Design (DDD) but always got lost in definitions like "a set of principles and patterns for optimal object systems" — this one is for you. 👌🏼 Our Lead Jmix Trainer, Dmitry Vashchenko has written a practical breakdown that cuts through the theory: 📍Demystifies DDD using a real-world manufacturing ERP as the example 📍Shows how to apply it in enterprise development with Jmix 📍Keeps it grounded — code, architecture, and real trade-offs included What you'll take away: ✅ How to avoid letting "pure" DDD become a liability ✅ Why isolating the domain model actually matters in practice ✅ How to balance DDD principles with auto-generated CRUD, REST, and UI Five minutes. No fluff. ⚡️ Java developers tired of architectural regret — this breakdown is worth your time. Follow the link. eu1.hubs.ly/H0stt0g0

Friday developer content! We had so much fun talking to @RichardFichtner (Java & Vaadin champion, co-founder of JCON conference), who visited our cozy YouTube channel recently! Our Community Manager Viktoriya Klementeva interviewed Richard and uncovered a few fascinating things, including: • why Java frameworks might actually be good for your health • the most embarrassing moment in Richard’s developer career • how joining a Java User Group could literally save your marriage! Watch the interview if you enjoy honest developer stories, Java community insights and a few laughs along the way. eu1.hubs.ly/H0spHKK0 BONUS for the viewers: 50% discount for visiting JCON Europe 2026 (Cologne, 20-23th of April)!

Friends, we're starting a series of posts about the new 2.8 release. 📍Inside Jmix 2.8. A missing piece for Fragments - Facets. Have you ever had the feeling that something was missing? Of course – there was no support for facets in fragments! But in Jmix 2.8, you will finally be able to use facets just like you do in views! The standard set of facets is supported: ⏺️ timer ⏺️ fragmentSettings ⏺️ fragmentDataLoadCoordinator ⏺️ urlQueryParameters ⏺️ dynamicAttributes Now you’ll be able to load data and save component settings inside fragments with just a couple of lines in XML (screenshot).

Many enterprise apps need reporting. But do they really need a heavy BI stack or a complex report designer? (spoiler - not always). 🤔 In our NEW article on Dzone our developer Sergey Yudaev compares three popular Java reporting options - JasperReports, Eclipse BIRT, and Jmix Reports - from a practical developer perspective: 📍what’s the setup like? 📍how do you design reports? 📍and how easily can they be integrated into your application? Jmix keeps things simple: no new designer to learn, but still a true WYSIWYG authoring process where you create data rich reports directly in target formats (XLSX, DOCX, PDF, and more) for predictable, production ready output. Jmix also makes it easy to build a custom portal to serve those reports to users. One of the key takeaways: reporting automation is essential; onboarding visual report builders is optional. If you're choosing a reporting tool for your Java project, this comparison is worth a look. Read the full article: “Comparing Top 3 Java Reporting Tools” on DZone. eu1.hubs.ly/H0sjcGl0

In most large organizations, Shadow IT blooms when central IT can’t keep up with the backlog of digital requests from business units. And while low-code tools promise to bridge that gap, they often create another problem: ❌ Siloed tech stacks, vendor dependencies, and projects that can’t scale or integrate without expensive vendor services. ✅ Jmix solves this differently! We give dev teams a fast lane that doesn’t sacrifice control or standards: ✔️ AI-assisted development in Jmix Studio helps your Java devs build real features faster. ✔️ Visual scaffolding tools accelerate delivery without enforcing a proprietary model. ✔️ Built on Spring Boot + Java + powered by IntelliJ IDEA - not a black box, widely adopted. ✔️ Cloud-ready and easy to embed into any PaaS workflow ✔️ Secure, composable, and observable by default. It’s not shadow IT when your developers can ship fast, in tools they trust, with code you can audit 💪🏻 ➕ Developers stay productive. ➕ Architects keep the landscape clean. ➕ CIOs stay in control. Develop smart - not hard!
