Batch API (JSR 352) Hands-on Lab

Hand's on Labs

The Batch API for the Java Platform (JSR 352) brings a standardized batch programming model to the Java EE platform. Through simple exercises, this hands-on lab introduces this important API and its key concepts (job, steps, JSL, chunked, batchlet, and more). You are then guided to enhance those exercises to use more-advanced concepts such as listeners to intervene in the batch lifecycle, checkpointing, partitioned step executions, and so on. The lab also demonstrates some GlassFish-related features such as querying batch job status, querying job metrics, starting, stopping, and restarting batch jobs from the admin CLI and console.

Java EE 7 Batch Processing in the Real World


This talk will explore one of the newest API for Java EE 7, the JSR 352, Batch Applications for the Java Platform. Batch processing is found in nearly every industry when you need to execute a non-interactive, bulk-oriented and long running operation task. A few examples are: financial transactions, billing, inventory management, report generation and so on. The JSR 352 specifies a common set of requirements that every batch application usually needs like: checkpointing, parallelization, splitting and logging. It also provides you with a job specification language and several interfaces that allow you to implement your business logic and interact with the batch container. We are going to live code a real life example batch application, starting with a simple task and then evolve it using the advanced API's until we have a full parallel and checkpointing reader-processor-writer batch. By the end of the session, attendees should be able to understand the use cases of the JSR 352, when to apply it and how to develop a full Java EE Batch Application.

Java EE 8, a snapshot overview


Java EE 7 was released 18 months ago and from J2EE to Java EE 7, much has changed but we are not done yet! Through the years, Java EE has always reinventing itself. Java EE 8 will be no exception to this rule! In this session, we will look at the Java EE 8 plans. We will review the various new JSRs that will be part of Java EE 8 (e.g. MVC JSR, JSON-B JSR, Security JSR, ...). We will obviously also looks how the existing technologies will evolves for Java EE 8 (eg. Servlet 4 with bring HTTP/2 support, JMS's plan to replace Message Driven Beans, CDI/EJB alignment, JAX-RS 2.1, etc). We will conclude this session by looking at how you can get involved in those works. This session will give you a good understanding on what Java EE 8 will looks like.
