Java Web Development (JSP/Servlets) Services

If you’ve ever tried to scale your organization’s data infrastructure beyond a few teams, you know how fast a carefully planned “data lake” can degenerate into an unruly “data swamp.” Pipelines are pushing files nonstop, tables sprout like mushrooms after a rainy day, and no one is quite sure who owns which dataset. Meanwhile, your real-time consumers are impatient for fresh data, your batch pipelines crumble on every schema change, and governance is an afterthought at best.

At that point, someone in a meeting inevitably utters the magic word: data mesh. Decentralized data ownership, domain-oriented pipelines, and self-service access all sound perfect on paper. But in practice, it can feel like you’re trying to build an interstate highway system while traffic is already barreling down dirt roads at full speed.

JavaFX is a versatile tool for creating rich enterprise-grade GUI applications. Testing these applications is an integral part of the development lifecycle. However, Internet sources are very scarce when it comes to defining best practices and guidelines for testing JavaFX apps. Therefore, developers must rely on commercial offerings for JavaFX testing services or write their test suites following trial-and-error approaches.

This article summarises the seven most common mistakes programmers make when testing JavaFX applications and ways to avoid them.

JGraphlet is a tiny, zero-dependency library for building task pipelines in Java. Its power comes not from a long list of features, but from a small set of core design principles that work together in harmony.

At the heart of JGraphlet is simplicity, backed by a Graph. Add Tasks to a pipeline and connect them to create your graph. Each Task has an input and output. A TaskPipeline builds and executes a pipeline while managing the I/O for each Task. 

As you may have already guessed from the title, the topic for today will be Spring Boot WebSockets. Some time ago, I provided an example of WebSocket chat based on Akka toolkit libraries. However, this chat will have somewhat more features, and a quite different design.

I will skip some parts so as not to duplicate too much content from the previous article. Here you can find a more in-depth intro to WebSockets. Please note that all the code that’s used in this article is also available in the GitHub repository.

Replatforming from Java 8 to the newer Java versions has proven to be a huge challenge due to potential compatibility issues and changes in language specifications. The Spring Framework, which provides a programming and configuration model for modern Java applications, has just released its latest major version, Spring Framework 6.2.10, and it requires a baseline of Java 17 or higher. Because of this, migrating from an older version like Java 8 would involve code modifications, which take considerable effort and rigorous testing.

Before diving deep into version upgrades for Java applications, let us first discuss what Amazon Q developer is and how it helps developers with application modernization.
