Gastón C. Hillar | January 2009 | Microsoft
In order to solve problems that arise in concurrently running threads in applications, we need new debugging techniques suitable for the new parallelism environments that occur in Visual C#. In this article by Gastón C. Hillar, we will learn many tricks and debugging procedures that will help us find solutions to multithreaded application problems and have a better understanding of the execution of parallel threads. We will be performing the following exercises:
- Learn some tricks to prepare multithreaded code to simplify the debugging and troubleshooting processes
- Become skilled at watching and understanding the execution of multiple concurrent threads
EJB 3 Entities
by
Michael Sikora | January 2009 | Java Open Source
Entities are classes that need to be persisted; their state is stored outside the application, typically in a relational database. Unlike session beans, entities do not have business logic other than validation. As well as storing such entities, we want to query, update, and delete them. In this article by Michael Sikora, we will cover the following topics:
- EJB 3 entities
- Java persistence API
- Mapping an entity to a database table
- Metadata defaults
- Introduction to the entity manager
- Packaging and deploying entities
- Generating primary keys
- Overriding metadata defaults
