Jakarta Batch in Practice: Reliable Chunk-Oriented Processing for Enterprise Workloads

Batch processing remains vital because many business operations aren't suited to interactive requests. Tasks such as recalculating prices, reconciling transactions, migrating records, generating reports, processing invoices, reclassifying customers, or applying rules across millions of records may require considerable time. Handling these as standard requests leads to fragile systems, increased user wait times, frequent timeouts, challenging retries, and possible data inconsistencies.

A batch model handles large workloads predictably, incrementally, and with control over progress and recovery. Rather than processing a massive operation as a single loop, batch processing uses jobs, steps, chunks, checkpoints, filtering, and restartability. This approach separates long-running data tasks from the user experience while delivering a structured execution model. In this article, we will focus on Jakarta Batch and examine its sustained relevance for modern enterprise applications.

Jakarta Faces Flow Scope: Managing Multi-Step UX Without Session State

Multi-step flows are common in UX, including onboarding, checkout, account setup, approval processes, configuration wizards, and administrative tasks. These require users to move through multiple screens while continuing a consistent working state. The challenge is to keep this state active for the duration of the interaction, but not beyond. Request scope is too short, while session scope often extends longer than the business process needs.

Jakarta Faces handles this with @FlowScoped, which manages state based on the lifecycle of a flow instead of a single page or the entire session. This article uses a customer segmentation application to demonstrate how a flow can guide users through configuration, preview, and confirmation, while maintaining state across each step. This approach creates a cleaner model for wizard-style UX: the scope begins when the user enters the flow, persists during navigation, and ends upon exit.

How to Build an AI Agent to Generate Selenium WebDriver Tests in Java: A Practical Guide for Test Automation Engineers

Artificial intelligence is transforming software testing by enabling faster test creation, smarter execution, and more efficient quality assurance processes. With AI agents, we can generate test cases and scripts, run tests, and produce detailed reports with minimal manual effort.

AI agents are software systems that leverage artificial intelligence to achieve goals and perform tasks on behalf of users. They can think through problems, plan actions, and remember things, while also making decisions on their own and improving over time.
